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
