Re: capturing sound card output

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

  It will depend on your sound card. I am able to select the "capture" 
to be the output mix using the alsa mixer (intel8x0).  But this means 
(in my case) the signal goes into the analog domain and is not as clean 
as I would like.

  There are other ways to capture the sound, for example

http://www.vsound.org/

  It might not suit your case if several programs are generating the 
sound opening and closing /dev/dsp.


  Why not physically connect the output of your sound card to the input :-)
You just need the right cable ?  (Make sure the output is not 
monitoring the input to avoid feedback)


cheers Paul
