the reason why jpcsp can decode the video is because its just standard h264 format that most players can play
.
the only way to decode audio would be to reverse engineer the format and no one has been up to the task yet.
so the alternative is to decode the files on the PSP there you can get a raw file like PCM and then jpcsp can understand the file.
Just thought this is something interesting about the long-standing discussion of decoding at3 (as an alternative to downloading SonicStage):

I believe this is the relevant file (as an alternative to downloading SonicStage - look for atxdec.ax and atxparser.ax):

Also, weren't ffmpeg able to get Atrac support and they're not Sony affiliated?

Forgive me if I'm just repeating known information as I'm a bit of a noob here and still in uni.
