MultiCD supports several compression formats to reduce sound file size:
Format Compression Decompressed size Channels
3 to 1 3 samples/byte 8 bits mono only
6 to 1 6 samples/byte 8 bits mono only
IMA4 2 samples/byte 16 bits mono/stereo
mu (µ) law 1 sample/byte 16 bits mono/stereo
A law 1 sample/byte 16 bits mono/stereo
differential 2 samples/byte 8 bits mono/stereo
Fitting more sound samples per byte results in smaller sound files, more bits on decompression gives better sound playback quality.
Support for 3 to 1, 6 to 1, IMA4, mu law and A law is built into the system software. To play back differential compressed sounds requires adding an extension in your system folder. Details on this can be found in the About Decompressors document.
