| ADPCM This
method of encoding sound data files takes up less storage space than the
regular PCM format used by WAV and AIFF files--and CD audio for that
matter. ADPCM comes in more than one flavor: IMA's ADPCM, for example, is
used on the Sony Mini Disc to cram more data onto a smaller platter;
Microsoft ADPCM is used as part of Windows 95's canon of audio codecs. |
