Offset Size Description

0000 L Uncompressed data length

0004 «ID» A1 01 00 10 for ADPCM compression, 00 00 00 00 for standard compression

0008 W Number of times the sound will be repeated minus 1 (ie 03 for 4 times)

000A B Volume setting: from 01 (minimum) to 05 (maximum)

000B B Always 00?

000C L Time between repeats in millionths of a second (000F4240 for one second)

0010 «LListB» Sound data

Standard compression uses (about) 8.3 kHz 8 bits sampling. So each byte records a volume.

ADPCM compression is a standard that can be looked up elsewhere (OK, this is a cop-out; I will document it at some later time).
