The raw data part of a SNDD file contains the actual audio samples without any other headers.

To create a wav/aif file one needs to write a file header like below and then write the contents of the raw data part.
Write "RIFF", add the size of the part in the raw file + 70 byte, write "WAVE", write "fmt ", add the wav header + change it's first byte from 8 to 32, write "data", add the size of the part in the raw file, add the raw file data and save it as a wav file.

dat

There are 2 different formats used by the SNDD files.

PC retail

Below is the dat file part used in the PC retail version.

Offset Type Raw Hex Value Description
0x00 res_id 01 D7 08 00 2263 02263-comguy_dth2.aif.SNDD

0x3E int16 37 00 55 duration in 1/60 seconds
0x40 int32 56 28 00 00 10326 size of the part in the raw file in bytes
0x44 offset 20 10 59 00 00 59 10 20 at this position starts the part in the raw file
0x48 char[24] AD DE dead unused


PC demo and Mac

The Mac version and the PC demo version use a simpler format. It appears that there is no support for different sample rates (all sounds are sampled at 22050 Hz).

0x14 offset 00 B1 01 00 00 01 B1 00 at this position starts the part in the raw file
0x18 char[8] AD DE dead unused


raw

The raw data part of a SNDD file contains the actual audio samples without any other headers.

export and import

To create a wav/aif file one needs to write a file header like below and then write the contents of the raw data part.

WAV files

  • Write "RIFF"
  • add the size of the part in the raw file + 70 bytes
  • write "WAVE"
  • write "fmt "
  • add the wav header + change its first byte from 8 to 32
  • write "data"
  • add the size of the part in the raw file
  • add the raw file data
  • save it as a wav file.

Offset Type Raw Hex Value Description
Complete ADPCM wav format header (black outline)
0x00 char[4] 52 49 46 46 RIFF identifier for the "IBM/Microsoft RIFF" standard
0x04 int32 9C 28 00 00 10396 size of the file from 0x08 to the end (= size of the .raw part + 70 bytes)
0x08 char[4] 57 41 56 45 WAVE identifier for the "WAVE" format
0x0C char[4] 66 6D 74 20 fmt identifier announcing the following wav format header
0x10 block[54]     wav header; note that it starts with a 32 and not with an 8
0x46 char[4] 64 61 74 61 data identifier announcing the following wav data
0x4A int32 56 28 00 00 10326 size of the following wav data in bytes (= size of the .raw part)


AIF files

  • Write "FORM"
  • add the size of the part in the raw file + 50 bytes
  • write "AIFC"
  • write "COMM "
  • add the aif header + calculate its sample rate (always 22)
  • write "SSND"
  • add the size of the part in the raw file + 8 bytes
  • add 8 zero bytes
  • add the raw file data and save it as an aif file.

0x32 int32 00 00 00 00 0 offset; determines where the first sample in the data starts; in Oni it's always zero
0x36 int32 00 00 00 00 0 block size; used in conjunction with offset for block-aligning data; in Oni it's always zero
