Hi all,
I would like to capture the sound currently played back by my sound card.
Using Linux I would use "vsound"-command to grap /dev/dsp for this approach.
Now I'm on Mac. And I want to implement the same technique.
I looked into the documentation of CoreAudio and found the HAL plugins
interesting. But I'm not sure... am I on the right way?
Maybe implementing CoreAudio/AudioDriverPlugIn.h?
Or is there something equivalent to /dev/dsp on Mac?
If there is some open source implementation / demo / project out
there this would be amazing too :)
I really just need to capture the raw audio data currently played back.
Best for me would be to have a Java solution. But if this is not possible I
also would implement something in Obj-C / C to get this done.
Thanks a lot and regards from munich,
Aron
p.s.: In result, I will create an open source app to live-encode all
whats currently played in MP3 and stream that over HTTP. I
will use that local mp3-stream to feed the PS3 Media Server.
So I should get my normally locally played back sound, wireless played back on
my Teufel Sound System using PS3 / MP3 / Media Server streaming
in nearly maximum quality.
