Hi everyone,
I'm making some play&record experiment with two separate multi-channel ASIO devices (for input and output).
So, couple of issues I've encountered:
1) MATLAB can't handle multichannel devices.
So I found pa-wavplay package by Matt Frear
http://www.mathworks.com/matlabcentral/fileexchange/4017
that make it possible to use multichannel device with MATLAB.
At that point two additional problems pop up.
2) Varying latency times
Since I'm making many tests, it is very important to be synchronized, meaning the latency times should be constant every run.
According to Robert Humphrey, playrec utility
http://www.playrec.co.uk/
should deal with that problem.
However, common problem to pa-wavplay and playrec is the usage of PortAudio, which can not handle two separate ASIO devices for input and output simultaneously.
So I'm kind of stuck in here.
Anybody else encountered such a problem?
Is there any solutions somebody knows?
