OBD:OSBD/OSIm

Offset	Type	Raw Hex	Value	Description
0x00	tag	6D 49 53 4F	OSIm	Oni Sound Impulse
0x04	uint32	68 00 00 00	104	104 bytes; size of the part that follows
0x08	uint32	06 00 00 00	6	version (see below)
0x0C	char[32]	6B 6F 6E...	konoko_wakeup	group name (reference to 06590-konoko_wakeup.grp.OSBD)
0x2C	uint32	01 00 00 00	normal	priority of the group; the following priorities are possible (values in dec): 0 - low 1 - normal 2 - high 3 - highest
0x30	float	00 00 20 41	10.0	distance at which the maximum volume is heard
0x34	float	00 00 48 42	50.0	distance at which the minimum volume is heard
0x38	float	00 00 B4 43	360.0	angle at which the maximum volume is heard
0x3C	float	00 00 B4 43	360.0	angle at which the minimum volume is heard
0x40	float	00 00 00 00	0.0	amount of attenuation at min volume angle
0x44	uint32	00 00 00 00	0	"alternate threshold"; maximum number of the group of this impulse that can be playing at once (present for version 4 and above, default is 0)
0x48	char[32]	00...		alternate impulse name; impulse to play if "alt threshold" copies of this impulse are already playing (reference to another imp.OSBD file, present for version 4 and above, default is empty string)
0x68	float	00 00 00 00	0.0	velocity at which an impact plays at full volume; if 0, always plays at full volume (present for version 5 and above, default is 0)
0x6C	float	00 00 00 00	0.0	minimum occlusion percentage; if 1, always plays at full volume, otherwise calculates volume by amount of environmental occlusion (present for version 6, default is 0)

Version: As explained on OSAm, there have been several versions of the binary format. Because lower versions lack certain fields, the addresses of the remaining content must be shifted backwards when reading it.; The above example belongs to the latest OSIm version encountered in Oni: 6.; Versions of OSIm occurring in Oni: 3, 4, 5, 6.
