Wav Header          Aif Header


Oni PC sound data uses an ADPCMWAVEFORMAT header.

Offset Type Raw Hex Value Description
0x0C int16 02 00 2 format ID (2 = ADPCM format)
0x0E int16 01 00 1 number of channels (1 = mono)
0x10 int32 22 56 00 00 22050 samples per seconds; (also known as "frequency" or "sample rate")
0x14 int32 93 2B 00 00 11155 File:Sndd hd1.gif
0x18 int16 00 02 512 block alignment; used for buffer estimation; (the block alignment of 22050 samples per second is

always 512 bytes)

0x1A int16 04 00 4 bits per sample
Special extended ADPCM wav format header (black outline)
0x1C int16 20 00 32 size of the following extended information part in bytes
0x1E int16 F4 03 1012 File:Sndd hd2.gif

N.B. For stereo, the -7 in the numerator is replaced with a -14. geyser (talk)

0x20 int16 07 00 7 number of the following coefficient sets
0x22 int16-16 00 01 00 00 256, 0
File:Sndd hd3.gif

The 14 coefficients are standard and are used by the wave to play.

The seven coefficient sets are preset. They must appear in this order.

0x26 int16-16 00 02 00 FF 512, -256
0x2A int16-16 00 00 00 00 0, 0
0x2E int16-16 C0 00 40 00 192, 64
0x32 int16-16 F0 00 00 00 240, 0
0x36 int16-16 CC 01 30 FF 460, -208
0x3A int16-16 88 01 18 FF 392, -232
