MPEG and WAV explained
MPEG-1 and MPEG-2 program streams are the formats behind Video CDs and DVDs. They are decades old and very inefficient by modern standards.
WAV stores uncompressed PCM audio — the raw samples, exactly as captured. A stereo CD-quality minute is roughly 10 MB, which is the price of having no compression whatsoever.
- Where MPEG files come from
- DVD rips, old camcorders and broadcast archives.
- Where WAV is used
- Recording sessions, sample libraries and audio editing.
