If you need to record or digitse sound professionally, you need a high quality analogue to digital converter. We test the PrismSound Titan - a high-performing, high-end USB audio interface

A/D converters are everywhere. Most of the time we don’t even think about them. You use one when you make a phone call. Does the quality matter? Not much: in absolute terms phone calls sound pretty terrible anyway. There’s one in your computer for when you use Skype. And video A/D converters sit behind every single camera sensor. Otherwise, we couldn't process or store the video digitally.

When you digitise something - anything - you will forever leave an “imprint” of the analogue to digital converter on the digital media that you make. You can’t escape this. There’s no way round it. All you can do is choose a converter that leaves the smallest signature possible, and that means choosing the best.

It’s often the quality of its sensor that is deemed to have the biggest effect on the look of a camera, and that is largely true, but it’s also the quality and the resolution of the analogue to digital converter that will determine the ultimate quality of the device.

Similarly, you do, of course, have to use the best possible microphones if you want to make a great audio recording, but if the characteristics of your analogue to digital converter aren’t up to scratch, then you’re doing the equivalent of looking at fine art through a beer glass.

It’s tempting to say that everything is digital these days, so why would it be that we even need analogue to digital converters? But there’s an all-embracing answer to this, which is that we (that’s us - people) are analogue. Apart from our DNA, which is arguably a digital code, we are analogue beings in an analogue universe. We make analogue sounds and we perceive them analogue-ly, if that’s a word.

Not only are we analogue, but everything we recorded before the digital audio era exists in analogue form as well. So it’s not just when you want to record a guitar or human voice that you’ll need an analogue to digital converter - you’ll need one when you want to digitise all those old tapes and records (and, if you’re a film archive - you’ll need one for the audio as well).

Preserving audio

It’s important to preserve the audio in vintage recordings, but it’s essential to keep the essence of the media as well. Even though it’s tempting to use software to remove noise, this should be done after the master archive has been made as a separately stored copy: it’s an irreversible process and it does throw away information, even though it might not be obvious that it is doing so.

Finally, when if you spend a lot of time building up a collection of great microphones, amplifiers and even mixing desks, these all have their analogue “sound”, and you would, of course, want to preserve these unique signatures. Only top-end converters can do this.


It’s a bit like the argument that to archive film digitally, you have to not only capture the image, but the film medium and the grain too.

Good analogue to digital converters are better than they have ever been, and it’s easier to connect them to a computer as well. USB is a very sophisticated interface (despite, surprisingly, being used mostly these days as a power supply for charging phones!) and replaces the need to have dedicated digital audio interface cards.


The PrismSound Titan is a top-end USB audio interface that’s designed to get audio in and out of your computer at the very highest quality. It’s not what most people would consider to be cheap, but when you consider the essential role it plays in digitising high quality audio, it’s not a high price to pay for anyone who would use it professionally.

The device comes in a full-width 1U rack and has a useful selection of inputs and outputs, balanced and unbalanced. A nice touch is that four of the input channels have selectable mic pre-amps, and any two of them can have high impedance, unbalanced instrument input jacks.
