BWAV/BARS Research Notes #2
Description
As mentioned in the readme, some of the BWAV files can play in VGMStream (such as BGM_Dragon_Darkness_Intro.bwav). Then you get some BWAVs that VGMStream cannot play, such as Dm_ED_0005.bwav (presumably the one played during the credits, due to its large file size).
Here, we can post some documentation on what we've found in some of these interesting BWAVs.
I've noticed that Dm_ED_0005.bwav doesn't contain any coefficients in its channel info. So this means that the coefs for DSP-ADPCM decoding are stored elsewhere (such as in the BARS file).
Also, Dm_ED_0005.bwav has 6 channels, rather than 2. This could mean that it has 3 separate tracks in one BWAV.
