Steinberg, being good natured types, have published the standard, and anyone is free to use it. The ASIO SpecificationĪSIO is free, sort of.

You can download it from his Web site here. I don't know how he’s done it, but clearly he’s a clever chap.

He has developed an ASIO driver which works seemingly with just about every sound card out there. Fear not if that’s not the case, Michael Tippach has come to the rescue. If you're posh like me, you may have a posh soundcard which provides ASIO support. If you're developing a serious real-time audio application, you're going to need ASIO. They created a standard called ASIO, which is designed to give low level access to your audio hardware using small buffers which minimises latency.

Adding a 1/100 th second delay to a sound will perceptibly alter it too, as if you were in a big room.Īnd this is the problem with DirectX, the buffer sizes it uses are just too big to make an effective real-time audio program, and this is why audio software bowfins Steinberg went about creating a new specification for low-latency audio drivers. Small eats up at performance, but minimises this delay. There is always a compromise in deciding what buffer size to use – large gives you great performance, but a delay. This is the minimum time it’s possible to hear a note after you strike a note on a keyboard. With a 441 sample buffer, you get a minimum latency of 1/100 th of a second, and a maximum of 1/50 th. The bigger the buffer, the greater the efficiency, but the greater the latency. A more reasonable approach is to interrupt the processor 100 times a second and get it to spit out a buffer of 441 samples each time. In practice, it is impossible to interrupt the processor that many times a second, so a system of buffering is used this helps keep the work to a minimum, and helps with things like IO when reading from disc or network. So, if we want CD quality audio, we need to be prepared to make 44100 reads and writes to the soundcard a second.

The more samples you use a second, the higher the ‘sample rate’ and the better the quality, in particular, in the higher frequency components of the sound. This works perfectly – to an extent.Īn audio stream is simply a flow of numbers or ‘samples’ which represent sound pressure. There are varying ways to do this, and in my first cut, I used DirectSound. If you want to develop an audio application, the first thing you're going to need is a way of getting the sound in and out of it – your soundcard. NET which, for me, is the best software development environment available at present. Instead, I'm interested in producing a stand-alone synthesiser and do so using.

It’s not in my brief to make anything VST compliant perhaps, if I were aiming for commercial success, I would go down this route. In particular, there are many commercial VST plug-ins available nowadays which are fully featured synthesisers and samplers which integrate with sequencers. In those days, these bits of kit had dedicated DSP chips in them to achieve their results, but the years have seen computers Moore’s Law themselves out, and there has been a general shift away from hardware sound modules to software counterparts. None-the-less, I still loved these machines and the rich textured sounds they could produce. Many years ago, I bought a lot of studio grade keyboards and rack units in the hope of putting them to good use making tunes, but as it turned out, I was a poor musician. Backgroundīeing a nerd, I'm currently revisiting a project I've done little bits on over the years. A bit like a bucket of Belgian lager, without the hangover. With this, a microphone, and a pair of headphones, you should be able to turn yourself into a low latency slurring idiot with minimum effort. Licensing restrictions prevent me from distributing it here.īecause the library on its own is somewhat dull, I've included a small console application to demonstrate its use – the slurring idiot application.

Please note that the source code supplied is not complete you will need to download the ASIO SDK from Steinberg in order to build and run it. This allows low level and low latency communication with soundcards, and might prove useful for those interested in developing audio applications – software synthesisers, recording applications, FX units, and such things. This article demonstrates a means of communicating with audio devices which support Steinberg’s ASIO drivers, from within.
