Castle of Shikigami 2 - sound downsampling problem

[DrEaMpLaY]

Hi.
My turn :D
I'd like to downsample music in Castle of Shikigami 2 from stereo to mono (to make shmups compilation). The sound file is named SND.BIN and has height = 236mb so it is quite big - 118 mb to downsample :D
That file have unknown format for me. I have sure that file is not in SFA, ADX, AFS or DCZ format. It has no header.

Look on the beggining of the file:

mmm... hard to guess, and if its not a standard format even if you knew how they encoded it and you were able to downsample it, the original BIN might not work with the downsampled file because frequency/rate is hardcoded....

maybe its just a big .RAW file.... and the program points to specific points inside the file to load the music
