Hi
this maybe isn't the place to post Asio related stuff but I didn't
find any dedicated Asio groups or such, which is pretty weird I think?
Anyway, I got the Asio SDK and everything is pretty straightforward,
using the sample I can easily play back wave files and do some
processing on them.
But there's one thing I don't understand how to do: the docs say the
callback should be in a different thread. Now, the callback function
is defined in
asioCallbacks.bufferSwitchTimeInfo = &bufferSwitchTimeInfo;
and there's a function bufferSwitchTimeInfo that handles the
processing, called whenever input and output buffers are ready.
I don't see how I can make a thread of this function? I mean, as far
as I know you have to create a thread, then start it. But I don't
think it's meant to be started on every callback? I just don't get the
point, so it would be great if somebody could give me some advice on
the correct way to do this. Or if any of you knows where to get Asio
specific groups/forums that would be great too!

Steinberg, the creators of ASIO have their own mailing list. There is a

If you want the low latency of ASIO but would like to support DX and WinMM
at the same time, take a look at PortAudio. www.portaudio.com
