Overview
DSPADPCM
is a data conversion utility for the Nintendo Revolution audio subsystem. This tool converts
standard WAV or AIFF files into the
DSP-ADPCM
format. This format is specific to the hardware decoder
built into the Revolution audio DSP and provides good data compression while retaining high fidelity.
The
DSPADPCM
tool can also convert
DSP-ADPCM
data back into WAV or AIFF formats. The conversion
process models the DSP decoder exactly and thus provides a convenient method for previewing com-
pressed data without relying on Nintendo Revolution hardware.
