From: Misty De Meo <mistyde...@gmail.com> This patchset adds support for the `APCM` chunk type in AIFF, which is used to store CD-ROM XA ADPCM audio. The only application I currently know of which uses this is the Sega Saturn game Sonic Jam, but there might be others. I've included a new fate test for this; here's the media file it uses: https://public.drac.at/S1_93.ADP
I've also fixed a minor bug that this exposed in the XA decoder. If the frame size isn't a multiple of 128 bytes, the decoder would leave the remainder unconsumed and it would be passed to the next adpcm_decode_frame() call. This most likely didn't come up before because the most common container (psxstr) has a frame size that's an exact multiple of 128. AIFF APCM files, however, use a frame size of 2324 bytes - the size of a mode 2 form 2 sector. That leaves a remainder of 20 padding bytes.
