LG SoundPop 360 Bluetooth speakers
– an example of the popular Bluetooth speakers

A very popular accessory for smartphones, tablets and laptops is the Bluetooth speaker. These speakers connect to your mobile device via Bluetooth and work as an audio output device for it.

The typical design for most of these speakers is to be a highly portable battery-operated unit that can fill a small area with sound in a manner equivalent to the typical portable radio. These appear in many different sizes from something that fits in your palm to larger tube-shaped units that can be carried using a strap or shoved in your coat pocket. Add to this an increasing number of larger cube-shaped speakers that put out a bass rich sound.

Add to this larger mains-powered bookshelf active speakers that have Bluetooth audio functionality in them along with a variety of inputs like analogue line-level and phono inputs or USB, SP/DIF and HDMI digital-audio inputs. These are being pitched as a way to set up a stereo for an office or small apartment.

In a lot of cases especially with portable speakers, these have a built-in microphone so they can become a speakerphone for your mobile device, something that can come in handy for conference calling including Zoom calls. But some Bluetooth speakers like the B&O Beosound A1 2nd Generation speaker even have this function set up so they work with your smartphone or tablet as a voice-activated smart speaker.

hese exist in a universe of Bluetooth audio endpoints like audio adaptors that work between a line-level audio connection and Bluetooth Classic audio as either a transmitter or receiver. This is in addition to home audio equipment receiving Bluetooth audio as an input and/or transmitting content available to it as a Bluetooth audio stream.

An example of this is in the form of portable and mantel radios that work as Bluetooth speakers. This device class has capitalised on the interest over the last 15 years in premium radios thanks to the likes of Bose and Tivoli offering radios that look and perform “above average”; the nostalgia for vintage-styled radios, along with broadcast radio being delivered via digital-broadcast technology or Internet technology and yielding programming exclusive to those technologies.

It includes companies offering audio source devices like turntables or CD players that stream to Bluetooth speakers. This is because the Bluetooth audio specifications are in fact “application-level” specifications that have been pre-determined for a long time, so there as surety that their source devices can work with any Bluetooth audio endpoint device. Here, it could allow someone to create an elementary sound system around that device and a pair of Bluetooth speakers.

Some of these speakers come with other features like LED-driven “party lights” or very large batteries that work as powerbanks for charging mobile devices. As well, a lot of larger portable Bluetooth speakers make use of passive radiators as a way to increase their bass response while others rely on an app-driven approach to allow you to adjust their sound quality from your smartphone.

Multi-speaker operation

But, thanks to Bluetooth 5, there has been an interest in multi-speaker Bluetooth audio approaches. This comes in the form of two operating modes:

Party Mode: Multiple speakers play the same programme content from the same source device with speakers that are stereo-designed playing the content in stereo across the speakers in that same box. This is to provide more sound coverage, typically for entertaining people at a party. Most such setups can handle a relatively large number of speakers due to latency not being considered important for this use case.

Stereo Mode: A pair of like speakers are set up so that one plays the left channel of a stereo programme source from one source device while the other plays the right channel of that same source. This is to improve the channel separation for the stereo content.

Typically manufacturers are limiting this functionality to a subset of their Bluetooth-speaker product range, more so the products in the “value” and “premium” market positionings.

These operating modes may work in one of two arrangements;

Source-to-speakers / hub-and-spoke: The source device streams the audio content to the speakers at once. This is typically implemented for stereo-mode operation so as to reduce latency by making sure the data gets to each speaker without any middleman device processing it.

Speaker-to-speaker / daisy-chain: The source device streams the audio content to one speaker which passes it on to other speakers down the line. This appeals to party-mode operation so as to permit large numbers of speakers to be in the setup. It may allow speakers to introduce some latency but this isn’t an issue for party-mode operation due to the goal of covering a large area with sound.

What to watch

Bluetooth LE Audio and its impact on Bluetooth speakers

Bluetooth LE Audio has been cemented in stone as the next-generation Bluetooth multimedia audio standard and is expected to provide a raft of improvements for this device class.

This implements the Bluetooth LC3 audio codec which is about efficient audio data transfer and even improve sound quality, operational stability and battery runtime. Here it also allows mobile-technology designers to avoid reinventing the wheel for audio-codec improvements when it comes to baseline audio performance for Bluetooth audio.

For portable Bluetooth speakers, this could be about allowing you to move around more freely with your mobile device without fear of losing the music as well as being able to run for a long time before needing to be charged up. As well, there will be the ability for these speakers and similar devices to cope with congested 2.4GHx wireless environments like in a city centre because of the robustness that the LC3 audio codec will offer.

This could impact how they are designed such as to have portable speakers that are lighter because of not needing to design around large battery packs. There will also be the chance to design higher-quality portable Bluetooth speakers that take advantage of higher quality sound that the new codec offers. Multi-speaker setups, especially based on Auracast, could be benefitting if the setup permits meshed or daisy-chained operation because of reduced latency in such setups and less impact on battery runtime for the actual sound reproduction.

Auracast broadcast audio will come in to its own with Bluetooth speakers that implement the Bluetooth LE Audio standard. Firstly, this could be about multiple-speaker party-mode operation without a requirement to use particular speakers from the same manufacturer. It may even allow the use of multichannel setups within the same Auracast multi-speaker setup rather than having “party mode” or “stereo mode” being mutually exclusive. Here, you would be using “audio sharing” on your phone, tablet or laptop to facilitate this mode with the device being enabled for Bluetooth LE Audio and Auracast.

As well, Auracast-based broadcast audio and Bluetooth speakers can be a perfect partner here. For example, a small Bluetooth speaker used in this context could be about close listening to an alternative soundtrack for video or other content or following an event going on in a nieghbouring area from another small room where you might be engaging in activity relating to that event.

Similarly, Auracast with Bluetooth speakers could be a logical follow-on to FM radio where listenership using BYO audio devices is desired for an event hosted in an area with a small footprint.

Previously, radio broadcasters were often collaborating with event organisers to broadcast the musical soundtrack to a large public event like a fireworks display, street parade or motorcade. Then you would have to bring a portable radio to that event and tune in to that station to follow the soundtrack using that radio to get the best value from that event. This approach may be seen as irrelevant for a radio station with a large broadcast area like a major city’s metropolitan area unless the event has a large footprint that takes in more of that broadcast area such as a fireworks display encompassing a waterway that passes through the city.

Similarly, there were the drive-in cinemas where you tuned your car radio to a particular frequency to hear the film’s soundtrack. Here, this was limited to what the FM band was about and issues like destructive multipath that could ruin your listening experience.

Here, Auracast could lead towards a license-free wireless audio distribution approach centred around Bluetooth speakers that implement Bluetooth LE Audio technology. It would also be about increased flexibility within the setup like multichannel speaker clusters (think stereo pairs or speakers plus subwoofer setups).

The Bluetooth LE Audio specification will also impact multiple-input operation for Bluetooth speakers. This could be about seamless multipoint operation when you want to use a speaker with a smartphone and laptop or allowing your party guests to contribute to the music at your party using their devices. It could also be about party speakers that work with Bluetooth LE Audio microphones for karaoke and PA usage.

How Bluetooth LE Audio will come in to play for devices like Bluetooth headsets and speakers is the availability of dual-mode system-on-chip circuitry for this class of device. This will allow devices to work in a Bluetooth LE Audio or Bluetooth Classic Audio mode depending on what Bluetooth device they are working with, so as to assure maximum compatibility.

What could be done

There could be an emphasis towards optimising for and promoting mesh operation within multiple-speaker setups. Here, it can be used to make these setups more robust including allowing you to position your smartphone or other source device near any of the member speakers to assure audio continuity.

Multi-speaker setups could also be about bass improvement such as to add a subwoofer in to a party-mode or stereo-mode setup to pump up the bass. This also includes use of speakers that implement separately-amplified bass drivers being capable of working as part of these setups, especially “stereo-mode” setups.

There could be less reliance on “app-cessory” operation for common advanced functionality like tone control or lighting control. This could be facilitated with application-level functionality in Bluetooth LE Audio for these functions and avoid the need to create buggy apps for mobile and desktop platforms.

Manufacturers could look towards offering a variant of their Bluetooth speaker designs that has a broadcast-band radio tuner built in. Here, if you had already bought a particular speaker and then know there is one of the same design as what you already bought but has the radio functionality as well, you could justify buying the one with the radio so you can have a pair of speakers for party-mode or stereo-mode operation. It could also incentivise the manufacturer to design the speakers to work in multi-speaker mode for radio broadcasts as well as your phone’s audio.

It could extend to Bluetooth speakers that have line-input connections being able to stream the device connected to that input across a multi-speaker setup. This would extend the utility of that connection for multi-channel setups or party-mode setups.

Other complementary standards could be worked on to bring more utility out of the Bluetooth speaker class. For example, the HDMI-ARC standard could be worked on in a manner to support delivery of multiple soundtracks for the same video content. Here, this could incentivise the development of soundbars and AV receivers that allow streaming of different soundtracks to Bluetooth audio endpoints associated with the same device. That could allow a viewer to hear an alternate-language or audio-described soundtrack for video content using a Bluetooth headset or speaker paired to the soundbar or AV receiver while others hear the main soundtrack for that same content through that soundbar.

What I see that will affect Bluetooth speakers is the next few model cycles is to have Bluetooth LE Audio support as a heavily-marketed feature that will improve how they operate in many ways. It is something that I would see drip through a manufacturer’s Bluetooth audio product range.

Use security keys to sign in to your Apple ID account on iPhone (Support article)

My Comments

Apple is making it feasible to use hardware security keys in iOS as an authentication factor for their Apple ID logon.

This is being desired as a “phish-proof” approach for secondary authentication or sole authentication due to a physical device not being easily coerced or fooled. As well, this “machine-to-machine” approach allows for stronger passkeys.

It is even seen as a preferred secondary authentication factor for online services used by journalists, human-rights defenders, the public service within democracies and others working with high-stakes information. This avoids such users being fooled in to releasing their online accounts to highly-targeted spear-phishing attacks.

Apple supports this on iPhones and iPads through the iOS/iPadOS 16.3 major feature update. This is also being written in to MacOS Ventura 13.2 for the Apple Mac regular computers whereupon you just use the security key as the secondary authentication factor. They primarily implement this as an alternative secondary authentication means to transcribing a six-digit number shown on your iPhone when it comes to two-factor authentication for your Apple ID.

In the context of the Apple Watch, Apple TV and HomePod devices, you use your iPhone that you set up with the security key authentication to provide the secondary authentication factor when you set these up for your Apple ID. Here, this is easier for limited-interface devices because another device is managing some of the authentication work with your Apple ID.

FIDO-compliant hardware security keys are supported with this update but they have to have an MFi Lightning plug or NFC “touch and go” interface to work with the current crop of iPhones in circulation. USB-C is also supported but you would need a USB-C to MFi Lightning adaptor for iOS devices except newer iPads that have this connector. You also may find that newer iPhones that are to come on the market soon will have the USB-C connector due to pressure from the European Union and some other jurisdictions.

There will be a requirement to set up two hardware keys with the same iOS device when you implement this feature. This is so you have a backup key in case the one you lose the one you regularly use or that one is damaged such as being laundered with your clothes.

Add to this that support does exist for app-level or Website-level verification with security keys within iOS. But it may allow Apple to build in and refine the necessary application-programming interfaces for third-party app developers who want to support this form of authentication.

What I see at least is the implementation of hardware security keys in the mobile platform context when it comes to multi-factor or password-free authentication for the user’s primary platform account. Who knows when Google will offer this feature for Android. Could this also be about leading towards the use of hardware security keys as a hardening factor for user account security?

There are times where use of public accounts isn’t appropriate

The murky world of politicians’ covert social media accounts (sbs.com.au)

My Comments

Just lately there have questions raised about how Australian politicians and their staff members were operating multiple online personas to disparage opponents, push political ideologies or “blow their own trumpet”.

It is being raised in connection with legislative reforms that the Australian Federal Government are working on to place the onus of responsibility regarding online defamation on whoever is posting the defamatory material in a comments trail on an online service. This is different to the status quo of having whoever is setting up or managing an online presence like a Website or Facebook Page being liable for defamation.

Here, it is in the context of what is to be expected for proper political communication including any “government-to-citizen” messaging. This is to make sure we can maintain trust in our government and that all political messaging is accurate and authentic in the day and age of fake news and disinformation.

I see this also being extended to business communication, including media/marketing/PR and non-profit advocacy organisations who have a high public profile. Here, it is to assure that any messaging by these entities is authentic so that people can build trust in them.

An example of a public-facing online persona – the Facebook page of Dan Andrews, the current Premier of Victoria

What I refer to as an “online persona” are email, instant-messaging and other communications-service accounts; Web pages and blogs; and presences on various part of the Social Web that are maintained by a person or organisation. It is feasible for a person or organisation to maintain a multiplicity of online personas like multiple email accounts or social-media pages that are used to keep public and private messaging separate, whether that’s at the business or personal level.

The normal practice for public figures at least is to create a public online persona and one or two private online personas such as an intra-office persona for colleagues and a personal one for family and friends. This is a safety measure to keep public-facing communications separate from business and personal communications.

Organisations may simply create particular online personas for certain offices with these being managed by particular staff members. In this case, they do this so that communications with a particular office stay the same even as office-holders change. As well, there is the idea of keeping “business-private” material separate from public-facing material.

In this case, the online personas reference the same entity by name at least. This is to assure some form of transparency about who is operating that persona. Other issues that come in to play here include which computing devices are being used to drive particular online personas.

This is more so for workplaces and businesses that own computing and communications hardware and have staff communicate on those company-owned devices for official business. But staff members use devices they bought themselves to operate non-official online personas. This is although more entities are moving towards “BYOD” practices where staff members use their own devices for official work use and there are systems in place to assure secure confidential work from staffer-owned devices.

But there is concern about some Australian politicians creating multiple public-facing personas in order to push various ideologies. Here, these personas are operated in an opaque manner in order to create multiple discrete persons. This technique, when used to appear as though many vouch for a belief or ideology, is referred to under terms like sockpuppetry or astroturfing.

This issue is being raised in the context of government-citizen communication in the online era. But it can also be related to individuals, businesses, trade unions or other organisations who are using opaque means to convey a sense of “popular support” for the same or similar messages.

What I see as being appropriate with establishing multiple online personas is that there is some form of transparency about which person or organisation is managing the different online personas. That includes where there are multiple “child” online personas like Websites operated by a “parent” online persona like an organisation. This practice comes in to being where online personas like email addresses and microsites (small Websites with specific domain names) are created for a particular campaign but aren’t torn down after that campaign.

As well, it includes what online personas are used for what kind of communications. This includes what is written on that “blue-ticked” social-media page or the online addresses that are written on business cards or literature you had out to the public.

Such public-communications mandates will also be required under election-oversight or fair-trading legislation so people know who is behind the messaging and these are important if it is issues-based rather than candidate-based. If an individual is pushing a particular message under their own name, they will have to state whether an entity is paying or encouraging them to advance the message.

This is due to most of us becoming conscious of online messaging from questionable sources. It is thanks to the popular concern about fake news and disinformation and its impact on elections since 2016 thanks to the Brexit referendum and Donald Trump’s presidential victory in the USA. It is also due to the rise of the online influencer culture where brands end up using big-time and small-time celebrities and influencers to push their products, services and messages online.

Monitoring of breathing irregularities

In-vehicle presence detection

From the horse’s mouth

Wi-Fi Alliance

Lisbon demonstration showcases how Wi-Fi Sensing can assist in a critical scenario | Wi-Fi Alliance

My Comments

The Wi-Fi Alliance is extending the Wi-Fi network technology beyond a local data network technology towards a presence and movement sensing technology.

This can exploit newer Wi-Fi technologies like Wi-Fi 5 onwards which implement MIMO multiple-RF-frontend technologies; or the increasingly-common multiple-access-point Wi-Fi networks. Here, it is about sensing disturbance in electromagnetic wave patterns that are the basis of radio technology whenever people or things move about.

A viable use case that has been demonstrated is a “child presence detection” setup for motor vehicles. Here, this detects the presence of a baby, small child or dog within a motor vehicle’s interior and alerts the driver to the child’s or animal’s presence. This is to avoid incidents like the toddler who was “forgotten” in a childcare facility’s minibus where the child was at risk of overheating for example due to it being asleep and out of sight in the vehicle.

This approach doesn’t just sense the presence of the child in a closed vehicle but also monitors biometric signs like breathing so it is a live person or animal. As well, it is based around two Wi-Fi access points within the vehicle – one on the driver’s side of the dashboard and one under the front passenger seat to create the sensing envelope. This is typical for most passenger cars with the front seat row and the back seat row but could be reworked for larger vehicles like station wagons or minibuses.

Once proven in a real world situation, this use case could be about a feature that is mandated by motor-vehicle safety standards bodies as part of a vehicle’s safety rating or as a mandatory feature for vehicles to have before they are on the market.

It is also being seen as a technology to identify whether someone in the house has breathing issues along with simple use cases like presence and motion sensing within the house for energy efficiency, security and convenience functionality in the smart home. I would also see it as a boon towards independent ageing at home by detecting falls for example.

What is happening is that Wi-Fi technology will come in to play for more than just a backbone for a home network. Here, it would be about safety or in-home healthcare that assures some form of independence. This is while it can still serve that role of a data network backbone.

Recently Elon Musk, the founder of Tesla and SpaceX, had bought out Twitter.

This takeover has been seen not as the kind of takeover where one wants to invest in a company but more of a political move. It came about in the runup to the 2002 Midterm elections in the USA, an election cycle that impacts members of Congress and significant state-level officials like governors and secretaries of state.

This is because this Midterm election cycle is a “do-or-die” moment for American democracy due to whether state officials or members of Congress that support Donald Trump and his election-denial rhetoric come in to power, with it being the first Midterms after the January 6 2021 insurrection on the Capitol which was about denying the legitimate result of the 2020 Presidential election.

The goal of this takeover was to convert Twitter in to a so-called “free-speech” social media platform like Parler, Gab or TruthSocial including to reinstate Donald Trump’s Twitter presence. This included the laying off of at least 4000 staff especially those involved in content moderation.

Here, Twitter has lost it as far as brand-safety and social respect is concerned with a significant number of household names removing their advertising or online presence from Twitter. As well, increasingly most of us are considering or taking steps to limit our presence on or remove ourselves from Twitter.

As well, this takeover has ended up in a spat between Elon Musk and Apple about the possibility of Apple removing the Twitter native mobile app from the iOS App Store. This is part of Apple’s effort to make the iOS App Store a clean bouse with content and apps that are fit for work and the family home. Lately, this has manifested in Apple destroying their Twitter account and removing its posts.

Competing social platforms

Facebook, Instagram, LinkedIn and Hive Social

The Meta-run social-media platforms i.e. Facebook and Instagram are acquiring new appeal as a business-to-consumer social-media presence. This is in addition to LinkedIn acquiring a stronger relevance in the business-to-business space. It is because these social networks are maintaining some form of proper content moderation that keeps them brand-safe and with some form of social licence.

For example, these platforms are being used by brands, public figures and the like as a means to distribute information “from the horse’s mouth” like press releases. This is in addition to them buying space on them to run their campaigns. Similarly, the established media are maintaining their presence on these platforms, typically as an “on-platform” presence for their news services.

Another network being put on the map is Hive Social which is being run as an alternative to Twitter with the same user experience. This is yet another platform with a centralised user experience but is facing some early problems due to its success as a Twitter alternative. Here, you may find that the service availability may not be strong and there will be some security issues.

Mastodon and the Fediverse

Another platform that has gained a lot of heat over the last few weeks is Mastodon. This is a decentralised Twitter-style social network where each “Instance” server works similar to a small bar or café where the staff have the finger on the pulse as far as the patrons are concerned. But each Mastodon Instance is linked to each other via the Fediverse which works in a similar way to email.

The Fediverse uses the ActivityPub publish-and-subscribe protocol and relies on interconnected servers and decentralised networking protocols. It is used by Mastodon and other services like PeerTube and Pieroma. In this space, each server for a platform is called an Instance and these link or “federate” with other servers to give the appearance of a large social network. But the Instance owner has the upper hand on what goes on in that Instance server.

These setups could also be seen as being similar to the bulletin-board systems that existed before the Internet was popular where most of them were interconnected using FidoNet as a means to store and forward messages and emails between the BBS systems.

When you create an account on a Mastodon Instance, you can add a link to a Website you run and this is used as a way to authenticate you. But you also have to add a link on your Website to your Mastodon presence for you to be authenticated, which then leads to a blue tick.

At the moment, there is support for only one user account per Mastodon Instance server so you can’t really run a “private” and a “public” account on the same Instance. It could work for people who use a particular Mastodon Instance associated with their work for public-facing posts as well as a private account for personal posts on a community Mastodon server. There doesn’t seem to be support for “group” accounts that can be operated by multiple users at the moment.

But with other open-source software efforts, Mastodon will be subject to continual tweaks and revisions to bring it to what people will want out of it. There may also be activity taking place to improve the establishment of Mastodon Instance servers such as porting to popular business server environments or integration with business-computing account datasets.

Other technologies worth considering

Online forums and similar technologies

Old-school “pre-social-media” technologies like online forums of the phpBB or vBulletin kind, or email-list platforms like listservs may have to be used. As well, the group functionality offered by Facebook, WhatsApp, Viber, Signal and Telegram come in to their own here as a limited-circulation Twitter replacement.

Blogs and news Websites

The traditional blog and the regularly-up;dated news Website or “update page” are becoming more relevant in this time. Here, these will be augmented with an RSS Webfeed or an email update offered by the site that comes out on a regular basis.

What can organisations, content authors and public figures do?

Organisations, content authors and public figures can keep a Website alive with the latest information if they aren’t already doing this. This would work really well with a blog or news page that is always up-to-date and these resources are best augmented with at least one RSS Webfeed that reflects the updates that are made.

The RSS Webfeed can be used to feed a reputable email-publishing platform like Feedblitz or Mailchimp so that people get the updates in their email inbox. Your LinkedIn, Facebook, Instagram or other brand-safe social-media presences can come in to their own here as well when you post a link to your latest posts there and are worth maintaining. As well, you could consider setting up shop on Hive Social which is becoming a viable alternative to Twitter.

Small-time operators should work with a Webhost that offers a range of online services at reasonable prices. These should include email, Website hosting and hosting one or two online services in a secure manner.

If you can, you may have to investigate creating a business-wide Mastodon instance. This is about having your own space that you control and is something that your IT staff or Webhost can offer, especially if they are familiar with Linux. Here, you could have usernames that reflect your workgroups or staff who want to have a public Mastodon account.

Let’s not forget creating online forums using the likes of bbPress, phpBB or vBulletin for your company or industry. Even vertical-market software that suits your organisation’s type or the industry it works in like religion or education could come in to its own.

Conclusion

The takeover of Twitter by Elon Musk as a political affair is showing that there is the risk of online services falling in to the wrong hands. Here, an emphasis is being placed on a plurality of social media and other online services that can be moderated to preserve sanity on the Internet.

Google is making its internal video-blurring privacy tool open source | Engadget

My Comments

There are objects you have to be careful of when you photograph them for the public Web. What I mean by that is public-facing social media accounts, blogs or similar use cases where the general public would see the content; or images being offered as stock photos for anyone to illustrate material with.

Such objects are things like vehicles with their registration (license) plates or documents that lie in the scope of a picture and they can easily be considered personally-identifiable information. Even tattoos on a person could be considered identifiable unless they are a common design.

What Google has done and is publishing as open-source is a software algorithm that follows an object like a vehicle’s number plate and blurs that object. This could happen not just in photos but in videos where that object is moving. Here, it avoids the risk of that kind of information being indexed by a search engine with optical-character-recognition abilities.

This can also come in to its own where an email address, Web link or QR code is part of an image and there is the desire to control the use of this data by people who see the image on the Internet or on TV.

It is being pitched towards creators or journalists who want to blur out personal-identifying information whether that be of themselves, their premises or people they know for content destined for the public Web. Typically this workflow will be in the form of creating and editing a “public copy” of the image they took and using that on the Website or social-media account.

But there may be some use cases where an identifier is required to be visible in the published photo. For example, when a vehicle is put on the market, having a visible registration number in the accompanying images of that vehicle in the online ad is an asset for buyers when it comes to checking that vehicle’s provenance.

What I would like to see with this software is for it to be repackaged as a free plugin for photo and video editing software. Or, better still, more photo/video editing software developer being encouraged to “bake” the privacy-blurring code in to a major version of that software.

Google Nest video doorbell – to support season-specific custom sounds

Learn how we fine-tune the Nest doorbell ringtones (blog.google)

My Comments

Desktop operating systems started using audio customisations since the late 1980s

From the late 1980s to the mid 1990s, regular computers and their desktop operating systems introduced various multimedia abilities including file-based audio recording and playback. This came along with various user-experience customisation options like background wallpapers and interface elements that can be set to a user’s preferred colours.

These functions came together in the form of the ability for users to determine what kind of sound the computer makes for particular events like the startup sound, error sound or new message notification.

This kind of customisability was extended in the 2000s with mobile phones supporting ringtone customisation including downloadable ringtones. This feature was seen as important as a way for people to know if it is their phone that is ringing when it rings.

But Google has added this kind of customisability to their Nest Doorbell which is a video doorbell that works via your home network and Internet. Here, they have started offering special ringtones for this product that people can use for particular occasions like Halloween, Thanksgiving or Diwali. This goes hand-in-glove with you decorating your house in particular ways for particular seasons.

These devices would support the seasonality of particular occasion thus allowing the customised sound to play for the duration of that occasion. This avoids the audible equivalent of leaving decorations up beyond the applicable season which can look tacky.

I most likely would see a lot of companies who sell network-connected doorbell / intercom systems start investing in ringtone customisations for these devices. This could include user-supplied ringtones usually in common audio file formats, enabling ringtones to be applicable for particular seasons or user-defined periods, or bringing in brands and talent to create custom ringtones.

You just never know what other “Internet-of-Things” devices and platforms will end up with user experiences that are customisable by the end-user in the same way that computers and smartphones have been customised by their users.
