0x24 char[32] city_amb01 sound name (reference to 06452-city_amb01.amb.OSBD of level 0)
0x44 char[4] 45 4D 4C 56 VLME sound geometry type; the following types are possible:


VLME (EMLV) - volume (axis-aligned box)
SPHR (RHPS) - sphere


0x48 float 00 50 87 C4 -1082.500000 VLME: xmin

0x54 float 00 50 87 44 1082.500000 VLME: xmax
SPHR: sound pitch
0x58 float 00 00 DC 42 110.000000 VLME: ymax
SPHR: field not present
0x5C float 00 00 CA 42 101.000000 VLME: zmax
SPHR: field not present
0x60 float 00 00 80 3F 1.000000 VLME: sound volume
SPHR: field not present
0x64 float 00 00 80 3F 1.000000 VLME: sound pitch
SPHR: field not present


Position and rotation
Like for other data types, those probably correspond to handles for runtime editing.
x, y, z are oriented the usual way (z+ = forward, x+ = left, y+ = up)
Position is in world units (decimeters). Rotation is in degrees, trigonometric.
Sound pitch
Actually a playback speed multiplier. Other multipliers specified in the OSGr.
Radii (SPHR)
What do they correspond to? Is the following correct?
  • r < rmin : volume = "sound volume"
  • rmin < r < rmax : volume = "sound volume" * (rmax - r)/(rmax - rmin)
  • r > rmax : volume = 0
Please confirm. geyser 15:56, 26 January 2007 (CET)
