Wav Header


Oni uses in the PC version the ADPCM wav format. The header of this format is explained below.

Offset Type Raw Hex Value Description
0x08 int32 08 00 00 00 8 size of the following complete header part in bytes; (it seems that Oni uses only the following first 8 bytes, though the complete size of the header is 50 bytes)
0x0C int16 02 00 2 format ID (2 = ADPCM format)
0x0E int16 01 00 1 number of channels (1 = mono)

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) {{OBDtr| 0x1A | int16 |C800C8| 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

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.
