How to: MP3 to WAV

Common uses
- Import audio into editing or DJ software.
- Prepare on-hold messages for phone systems.
- Use clips in samplers or games.
Tips for best results
- WAV cannot restore quality lost in the MP3.
- Expect much larger files.
When you need WAV
WAV is uncompressed PCM audio, the universal format for audio editors, DAWs, broadcasting systems, telephone on-hold systems and many hardware samplers. Editing a WAV avoids repeated MP3 encoding, which would add artefacts each time you save.
What to expect
A WAV file is roughly 10 MB per minute in stereo at 44.1 kHz, about ten times larger than a typical MP3. The sound will be identical to the MP3 you started with: converting cannot restore detail removed by MP3 compression.
