decodeadpcm.dsp

Decompress a 4-bit Intel/DVI format sample.

Function

This instrument is the adaptive delta pulse code modulation library routine. It is used internally when it is called by other adpcm routines to implement the decompression of 4-bit samples. Load this instrument using LoadInstrument() before loading other adpcm instruments.

Sound samples are compressed from 16-bit samples to 4-bit samples using the SoundHack program. These 4- bit samples are in the standard Intel/DVI format. This library routine decompresses the 4-bit samples so that they can be played by other adpcm instruments.
