[Openal] Audio Readback

[Yaniv Pe'er]

In my opinion it will be much easier and effective to use a software audio
library, not a hardware library with software emulation.

There is an open source application called Audacity which is quite good. I
use it myself for audio editing.

http://audacity.sourceforge.net/

 

I haven't looked inside the code, but I assume the source has a separate
audio library you may use.

 

Good luck with your idea though. Don't forget to let us all know if you're
actually going to do it.

Hmm....Here is a thought, would it be possible to write an output device
that would write to disk instead of to the audio system?  I never intiailly
thought of OpenAL for this but maybe it could allow for those writing
systems for something like movie output. 

If it hasn't been done, I would not mind taking a crack at it (although what
ever I write would probably just be good for a starting point).

In general, no.  One reason OpenAL avoids this is because of hardware
acceleration issues -- the extra bus traffic (two-way minimally) would 
hurt performance.  The portable implementation used on the various Unix
variants can apparently output to a file, though.  I don't think it can
do so in other than real-time, however.
