;Number of channels
:By design the number of channels is supposed to be the same as that of the referenced SNDDs (this implies that all the SNDDs in a group are supposed to have the same channel count).
:If for whatever reason the channel counts in OSGr and SNDD are ''not'' consistent, then the behaviour depends on whether the OSGr is referenced from an OSIm or from an OSAm:
:*the channel count in an OSAm's OSGr determines the channel count of the decompressed sound buffer, therefore mono SNDDs will sound 2x higher/faster if the channel count in their OSGr is set to 2, and stereo SNDDs (e.g., music) will sound 2x lower/slower if the channel count in their OSGr is set to 1.
:*the channel count in an OSIm's OSGr seems to have no effect if the SNDDs are mono, i.e. setting the OSGr's channel count to 2 does not result in a higher pitch. As for stereo SNDDs, apparently they cannot be used in an OSIm's OSGr at all.

;Bitset at 0x08
;Version
:bit 4 is always set
:Just as for other [[OSBD]], there have been several version of the binary format.
:bit 1 - dunno, set for... (fill in)
:Over time, some fields that used to be hardcoded became customizeable on a group-per-group basis.
:bit 2 - enables the fields at 0x14 and 0x16 (apparently; maybe it's a bool32)
:Thus, later versions include some extra fields as compared to earlier ones.
::if bit 2 is off, then the 0x18 field goes to 0x14 etc: everything shifted backwards by 4 bytes
:The above example belongs to the latest OSGr version encountered in Oni: 6.
:Lower versions lack certain fields, and the following content is simply shifted backwards.
