DWD (sounds) & DWM (music) are propriety formats for Diamondware's SDK[2][3]. They seem to be derived from VOC and MIDI[4].
- DWD files begin with the ascii
DiamondWare Digitized - DWM files begin with the ascii
DiamondWare Music
Format Details
DWD Specification[5]:
Byte # Description
------ -----------
00-22 "DiamondWare Digitized\n\0"
23 1A (EOF to abort printing of file)
24 Major version number
25 Minor version number
26-29 Unique sound ID (checksum XOR timestamp)
30 Reserved
31 Compression type (0=none)
32-33 Sampling rate (in Hz)
34 Number of channels (1=mono, 2=stereo)
35 Number of bits per sample (8, 16)
36-37 Absolute value of largest sample in file
38-41 length of data section (in bytes)
42-45 Number of samples (16-bit stereo would be 4 bytes/sample)
46-49 *Offset of data section from start of file (in bytes)
50-53 Reserved for future expansion (markers)
