Capturing audio from SDL versions

[arutema]

So I'd like to capture some audio from a few PSP games.

According to the SDL documentation, it should be possible to do this by setting the following before running PPSSPP.

Code:

$ export SDL_AUDIODRIVER="disk"

This does save a raw audio capture, but it doesn't appear to be in the expected 44100hz 16 bit stereo format when I try to import raw in audacity. It does seem to be 16bit stereo when I import raw in audacity, but I'm not sure what the sample rate is, as it sounds too fast at 44khz.

Has anyone done this before any know what sample rate to import as? Does it vary by game by any chance?
