# * Interleave is multiple of 0x10 (default), often +0x1000
# - PSX_bf PlayStation ADPCM with bad flags
# * Variation with garbage data, for rare PS2 games
# - HEVAG Vita/PS4 ADPCM
# * For some Vita/PS4 games
# * Interleave is multiple of 0x10 (default)
# - XBOX Xbox IMA ADPCM (mono/stereo)
# * For many XBOX games, and some PC games
# * Special interleave is multiple of 0x24 (mono) or 0x48 (stereo)
