[Alsa-user] redirect ALSA output - no sound card?

[Nick B. <nic...@qu...>]

Hi list,

I'm new to ALSA (and linux audio in general) and have a question for you 
all, perhaps this should be on the dev list but i'll try here first...

I would like to capture output from an arbitrary application which 
outputs to ALSA and allow this data to be read by my application. Can i 
do this with ALSA and if so how?

There is no sound card device in the system i am using, i just want to 
be able to access the audio data by some mechanism, shared mem, device 
file, pipe, api etc I've looked at the "file" plugin but i don't want to 
save the audio data i want my application to be able to access this data 
in real time. I also had a look at Jack but don't really get it (are 
there any good docs around?) and it seems Jack would limit me to only 
being able to capture from one application at a time, i need to have 
multiple instances of the input application running and outputting audio 
data.

Any ideas gratefully recieved,  thanks!

Nick
