Waveform Archiver

Waveform Archiver (WA, informally called WavArc) is a specialized archive utility for DOS, and its associated file format. It was developed by Dennis Lee.

It only compresses a certain class of WAV file. Other files types are supported but not compressed.

File structure
A WA file seems to be structured as a sequence of "member files", each of which begins with these fields:

(1 byte) Length of filename field (variable size) Filename (1 byte) Unknown, observed to be 0x00 (4 bytes) A FourCC-like identifier for the compression level. The following IDs are used: 0CPY 1DIF 2SLP 3NLP 4ALP 5ELP

Identification
WA files have no signature. Identification could be done by checking for one of the compression IDs at offset {2 + {the value of the byte at offset 0} }.
