Digital sound

Starting small

Our smartphone capability – (audio memos, sound recording apps for Android and Apple music recognition (Shazam) and streaming services.

The terminology and technology involved in audio is mind-boggling. You really have to be an expert to get your head around it – and I’m not going to try. There are a wide range of differences in Audio Formats – What is HiRes Audio? It would appear that Spotify has only just recently entered the field of HiRes audio. I’ll just take it as read that I want the best, if I possibly can get it. Currently Apple seem as good, if not better, than the rest.

How to play hi-res music and lossless audio on your iPhone

To get the best quality audio for iPhone and for Android, you may need to dip into those two articles. For the Apple user, you can use AirPlay to stream audio (Apple) to a different device (eg a TV or HomeHub), or use Bluetooth (both Apple and Android) – but Bluetooth is generally not up to the mark on both platforms. Alternatively you should seriously consider using a wired connection using the headphone jack (some Android) or a lightning to aux (headphone jack) dongle (Apple). On my MacBook I do have a headphone jack and when on the desktop it’s connected to a pair of powered Logitech speakers.

Streaming services and their apps

As mentioned above, there a huge set of services requiring you to set up accounts, and install apps – unfortunately (but understandably) most of the free ones are not ad free, which can be distracting …

My conclusions from this? We use Apple Music with the recently launched and integrated Classical service as well. Both of these are part of our Apple One subscription which we share with other members of our family. Three of the family still use Spotify, but our son in Australia uses Tidal (for HiRes streaming) and Soundcloud (for new music). You can (and I have) convert Spotify playlists to Apple Music playlists (and vice versa) and I have using this app – Songshift but there are other apps.

Then we turn to Audiophiles, and the world of digital to analog convertors. By an audiophile (in this instance) I’m really just talking about someone who wants to connect a better set of speakers to their digital devices than the internal speakers that are supplied with the device. [In other words I’m setting the bar very low.]

The starting point is to begin to understand the world of Digital to Analog convertors (DACs), so this video hopefully will give an introduction and explain what’s going on in this mysterious world of interconnecting equipment.


I’ll follow this with a couple of articles that you might wish to peruse ..

What is a DAC? And why do you need one? (from What Hi*Fi?)

What is a DAC and why would you need one? (from Digital Trends)

You want to use your mobile device as your music player? Use a lightning to USB dongle to connect Apple to a DAC and then to your speakers, or headphones, but be sure to get a Samsung ACTIVE USB to AUX dongle for Android phones, or a USB-C to USB-C (or USB-A depending on your DAC) dongle to connect to your DAC, and on to the headphones or speakers.

So, if you’ve got this far, you might wish to really play your music at the best quality that it has been stored in digital format on your device Watching these two videos might help – or confuse you even more!

For Android …

For iOS …


Recording and editing music/sound on your device – use Audacity, Garage Band (iOS, MacOS) or BandLab (Android or iOS).

Then we turn to digital sound playing systems.

A wide field of options including the portable MP3 player – but would anyone want one of these nowadays – and the smart home speaker (with voice assistant) – which we looked at last year, and is definitely a device to look at.

Finally integrating with your home HiFi system.

I wrote about my setup in 2016 and again in 2019 for the group. I also wrote about my experiences on trying to make iTunes work for me better back in 2018 – from this latter post, the MacMini and Plex still remain as part of my setup but I don’t use either to stream music, and iTunes is thankfully dead and buried – well almost!

So what has changed from 2016? Well the external speakers connected to the Marantz amp have disappeared to be replaced by a Sonos Beam Soundbar connected to a new Samsung TV. All the other HifI components remain and are connected to the Marantz amp which is in turn connected to the Sonos Connect “hub”. The Bose speakers are still connected to the Marantz amp, but are rarely used now as we now have an Apple HomeHub which I can stream to using AirPlay, and which can be integrated with the Sonos speakers (I now also have a Sonos Move portable speaker) to provide home wide sound.

It has to be said this is a technological project, rather than an audiophile one, as my hearing has deteriorated to the point where I couldn’t detect HiRes from ordinary sound anyway, and the last time we actually had the same music in the whole house must have been the week after we bought the HomeHub.

The Apple HomeHub is a delightful device – we can “talk” to it using Siri or from Apple Music, and link the Sonos devices to it so that we can direct music to different speakers as required. It’s also the heart of our SmartHome project – more another day, and will provide moths of technology challenges for me using the Apple HomeKit and the interfaces that are being developed to link smart devices to that platform.

The next project – we’re installing solar panels this week, with a battery and a gateway to link to link to the Grid (using Octopus flexible tariffs) – definitely a topic for next year when we’ve got it all sorted.

Jonathan sent me his Sound setup which I reproduce below …

Just for info. – my home audio/cinema set up has some similarities to yours.

When we moved to Cardiff we bought a new house in Pontcanna which was still being built and I took the opportunity to have wiring installed in the walls to ceiling speakers in three rooms. I took advice from an AV specialist who advised Sonos, Spotify, blu-ray player and mini mac for my digital collection. 

Sonos serves all 3 rooms, plus a portable speaker, via a marantz amp in the main tv room ( surround plus sub ) and Sonos amps in the other two ( stereo )

Spotify provides all my music needs and I never now use the mac. Nor do I have a CD player in the house since the blu ray/receiver packed up. My cds are all packed up in boxes in the loft! The only stuff I miss is Neil Young and Joni Mitchel after Neil left in a huff!

I have Samsung tvs in 4 rooms – 3 of them Smart and all of them now support Spotify, Youtube, netflix etc. We subscribe to Sky with a main Sky Q box in the main tv room and mini boxes in 3 others.

I’m really happy with it but conscious that the Sonos gear is now 12 years old. They keep trying to get me to upgrade. One day it will be inevitable I guess. Sky might be considered an expensive luxury but we all need one or two of those. It’s brilliant!

Autumn cleaning – maintenance

First, an overview

This article from Norton is as good as any at summarising what you should do by way of maintenance – regular tasks that will make your machine run smoother, and possibly faster.

Backups

There are built-in options supplied for both Windows and MacOS – there’s no real reason to look beyond these. This table (for Windows 10) shows the different methods you might consider. I’ve also included this article that might help you understand what your need to do. However, with Windows (it’s never straightforward) you have another option File History, which maybe a better option, as it focuses on saving files to an external hard disk.

For the Mac, I wouldn’t bother going further than TimeMachine. You’ve heard me rave on about the Mac, but it’s true. You may do things differently on a Mac, but they’re just easier.

The most important thing is to do Backups, and do them regularly. My TimeMachine does an incremental backup every hour to an external hard disk. So the most I can lose should the machine crash, is the last 59 minutes. Some items will be excluded from this backup (eg photos) as they are backed-up automatically to iCloud when I import them on to my machine.

Windows 10 and 11 Maintenance

Let’s start by looking at this short video. You’ll want to go back and watch it more than once. Although it is aimed at Windows 10, I think all the utilities mentioned are available from Windows 11 too.

If you prefer reading to watching, and you’re a Windows 11 user, you will possibly find this article useful. If you don’t trust yourself to do the maintenance regularly, then Windows 10 users might find this article useful as it tells you how to schedule automatic maintenance and what it will do, but if you prefer your instruction to be visual you could watch this video instead, or as well.

If it’s just a speed-up you want from your Windows 11 system, you could work your way through the list in this article, but I’d be tempted to do the more comprehensive list of tasks mentioned in the videos above.

MacOs Housekeeping

Here it’s more housekeeping than maintenance, there are some things you can do to improve performance on your Mac, regular maintenance (as mentioned above) is not really required. This article aims to make your machine run better and faster – I’ll have to read it!!

The software I use on my Mac is CleanMyMac X – this article describes what you should do to automatically do some decluttering, which is probably a good thing and which I run once in a while; it obviously recommends that you use CleanMyMac to do it. Quelle surprise!

Operating system updates and upgrades

These are usually well announced by Microsoft and Apple. Generally, if the update is described as a Security Update, you should do it immediately; if it’s described as a bug-fix, or a point release with new features, I would counsel waiting a while … perhaps a couple of weeks, before installing it. Of course you can leave your operating system to do these automatically, so check your settings (as described in the videos) and select the time that your updates will be done.

More substantial upgrades are less frequent and my advice is to wait a while before installing these as it’s always challenging to go back to a previous release, and sometimes the upgrade will affect the running of one of your applications. All serious software developers will apply to get advance access to operating system upgrades to test their software on the new platform; but even with this access some bugs may not appear until the operating system is “out-in-the-wild”.

Internet history, cache and cookie cleaning

These were covered in the earlier videos but you should probably do these quite regularly anyway. You might have noticed that cookies weren’t “cleaned-out”. That’s probably because the majority of them will be re-installed the next time you go to a website, and cleaning them will also mean you have to re-enter information again. Generally, with good anti-virus software these days, cookie cleaning is not essential, as the malware threat has been reduced before they’re added to the browser.

Anti-virus and malware checking

For the Mac I have MalwareBytes (supplied by my bank). For the PC/Windows you know that I recommend Widows Defender, as it’s more than adequate for the “ordinary” user who’s not surfing the dark web! It’s evident that Microsoft have upped their game in this area and you can also deploy other tools to protect your machine. Take a look!

Hardware upgrades – memory, batteries

You might wonder whether you’re up to upgrading memory or batteries on your laptop or desktop, but actually this is a relatively easy job. You can use components from Crucial for memory and hard disk upgrades, and they describe how to do it for specific machines, or you can search for compatible components on the internet. Search for the instructions on how to fit for the specific DIY task. You’ll feel a sense of pride when you’ve completed the task too! A triumph for “person kind” over the machine

A really good upgrade is to replace an old Hard Disk Drive (HDD) with a Solid State Drive (SSD). The performance enhancement you will experience will be noticeable. You can always deploy the old HDD as an external disk and maybe use it for your backups when you place it in an appropriate caddy.

If you’ve not got the courage to do it yourself, you can always ask We will fix your PC to do it for you.

Cleaning screens and keyboards

Often overlooked, your screen and keyboard can always do with a clean, and you’ll be surprised at the difference it makes – to your mood if nothing else. I recently purchased this kit from Amazon to clean screens, keyboards and TV.

Application housekeeping

Another often overlooked consideration. You should look at whether your software should be upgraded. If it was purchased through an AppStore then you should be able to find out if there’s an upgrade available – you may have to purchase it, but often the upgrade will be free. Often the software provider – if you’ve registered your ownership – will inform/advise you of an upgrade to a new version, or release. Generally bug-fixes are not chargeable, but you may have to pay for feature-enhancements.

Please be aware that it’s impossible to expect that a software developer will keep their software compatible with every release of operating system software, so if advised that this is the case you should seriously consider an Upgrade, or finding a replacement if the software passes “out-of-support”.

You should also look to see whether (as was mentioned in the videos) you actually need the software anymore. At best it might just be taking up disk space you might need, at worst (as it becomes more outdated) it might provide a “backdoor” for malware to enter your system and upset your life!

Some applications (as was mentioned in the videos) also have local data caches and backups (genealogy database software is notorious for this). As you exit your session you are prompted to save a backup – the question is … how many backups do you actually need!!

All-in-one solutions

For the PC/Windows you could look at CCleaner (free version) – I love this quote from the article “Macs don’t need standard cleaning” but I do have MacPaw’s CleanMyMac X on my machine, and I bought it! However if you’re a Windows user there’s a lot to be said to doing the cleanup manually following the suggestions mentioned in the videos, I have shown.

Miscellaneous – eMail, Contacts, Calendars, Reminders, Notes, Photos

Not strictly maintenance but something to bear in mind and perhaps make a regular task, is maintaining your “everyday” applications.

Do you need to keep all your eMails? It may be possible to Archive them outside the Mail application – thus making it run faster and more efficiently. You can also if you’re using a local mail client (recommended) occasionally rebuild, or optimise, the email storage. It’s just a database and it will run more efficiently if it doesn’t have a lot of redundant links to deleted messages, and the like, contained in it. You may be surprised at the large number of files (especially photos) that are stored in your email. Perhaps you should save them to a Photos app, or at least download them to a folder on your machine – they’d be more accessible there.

It’s surprising how many Contacts are duplicated, or how details and lists can get out-of-date. Always a good idea to review them and merge duplicates, edit changes and delete no longer needed entries.

Calendars are less needing of maintenance. If the day has passed, so what; it’s more important to know the forthcoming events are accurate and up-to-date. However recurring entries should be reviewed occasionally.

Again, like the above, it’s more important to keep Reminders up-to-date, and if you decide to use that utility, to stick to it. It’s an application that you shouldn’t use occasionally, you should commit to using it, and then be able to rely on it. As I demonstrated recently you can talk to it – as of course you can with a lot of utilities and applications.

Notes can become a bit of a dustbin, and I suppose you should be allowed to have somewhere you just dump stuff. However, they do have a very useful role in planning, and charting progress of a project, or a trip – especially when you can show completion with a bullet-point format. The functionality is always improving and now you can store website addresses, photos, maps, music and more in a note and then share it with someone else so that they can collaborate with you on the topic. It’s just a bit embarrassing when you look back at what you’ve “noted” and realise it never actually “turned-out-like-that”.

Finally Photos. Probably the biggest hard disk grabber of all. You need to plan a strategy for what you want to keep, the application you want to use to access them, or share them, and then – if at all possible – stick to your plan! Not always easy, but for your sanity, probably essential. The first task is to work out your duplicates. This is where DupeGuru comes in. Apiece of open source software that has proven to be a life-saver to me, and a tool that has allowed me to recover a lot of disk space. It works well with phoitos, but can also be used to find duplicates of other file types as well.

… and there’s probably more – over to you!!!
