About WAV and MP3 Formats
What is WAV?
WAV was introduced by Microsoft and IBM in 1991 and stores audio as uncompressed PCM samples. CD-quality stereo WAV (16-bit, 44.1 kHz) uses about 10 MB per minute, and every audio editor, DAW and media player can open it.
- Recording, editing and mixing in any DAW
- Mastering and archiving at full quality
- Broadcast, sampling and sound-design work
- Maximum compatibility with hardware and software
What is MP3?
MP3 was developed largely at Germany's Fraunhofer Institute and standardised in 1993. It discards sounds the ear is unlikely to notice, typically at 128-320 kbps, which makes files roughly a tenth the size of CD-quality WAV.
Commonly used for:
- Music libraries and portable players
- Podcasts and audiobooks
- Sharing audio by email or messaging
Why convert WAV to MP3?
MP3 plays on virtually every device and cuts file size by about 90%, which makes it the easiest way to share or stream a finished recording.
