Re: 4+ audio channels - matlab
Hello Virginie,
You can try out the Matlab functions implemented by Matt Frear using PortAudio. You can find the files at
http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=4017&objectType=File
In order to maintain audio synchronisation, it is best to use a single car with multiple channels rather than multiple cards with 2-ch each. Even then, the stereo channel groups will probably not be using the same clock.
Best,
Hüseyin

Subject: 4+ audio channels - matlab
Hello list,
does anyone have experience dealing with matlab (psychtoolbox in
particular) and 4+ audio channels soundcards? I currently have at
hand a PC equipped with a Realtek audio card which matlab does not
seem to recognize quite well (I am also concerned about the filtering
properties of this device) so I am thinking about using two audio
cards or 1 audio card providing more channels but I would like to
hear about potential issues with this kind of device (in particular
timing) and/or what recommendations you may have.
Thanks very much for your help!
Virginie
