Dear list members,
we develop an application which heavily uses QuickTime for audio playback. With Windows Vista, QuickTime, as still based on DirectSound, stopped to be hardware accellerated and cracks appear in the mixed sound output. Besides that, as of QuickTime 7.4, a very significant slowdown could be observed. We have finally decided to ditch QuickTime and use OpenAL, which seems to be a good replacement.
Reading OpenAL manual and thinking about the new app's structure, we have found difficulty in getting sound samples as our application either plays the audio back or exports mixed audio into a file (currently WAV, and AAC). We have read about capture device extension but are not sure if this is a way to go and what to do if this extension is NOT present (or at least it seems that it could be missing).
How do we get audio samples after they get mixed so we could stream them into a file?
Best Regards,
Petr Miksik
