# * For few rare games [Ikinari Maou (Switch)]
# * Interleave is multiple of 0x4 (default)

# - ULAW mu-Law 8-bit PCM
# * For few rare games [Burnout (GC)]
# * Interleave is multiple of 0x1 (default)
# - ALAW A-Law 8-bit PCM

# - IMA IMA ADPCM (mono/stereo)
# * For some PC games, and rarely consoles
# * Special interleave is multiple of 0x1, often +0x80
