- Convert and watch each file's status update.
- Download the WAVs individually or as a ZIP.
Where WAV is required
- Editing and production: DAWs and video editors decode WAV instantly and never add compression when you re-save.
- DJ hardware and samplers: many CDJs, drum machines and hardware samplers only read uncompressed files.
- Audio CDs: burning software expects 16-bit, 44.1 kHz WAV.
- Phone systems and speech tools: hold music, IVR prompts and many transcription services require WAV.
- Game engines and apps: WAV is often preferred for short sound effects because it plays with zero decoding delay.
Choosing a bit depth
| Bit depth | Size per minute (stereo) | Choose it when… |
|---|---|---|
| 16-bit PCM | ≈ 10 MB | You need maximum compatibility, including CD burning |
| 24-bit PCM | ≈ 15 MB | Your DAW session or client asks for 24-bit |
| 32-bit float | ≈ 20 MB | You'll process heavily and want headroom above 0 dBFS |
A note on quality
MP3 compression permanently discards some detail, and converting to WAV can't bring it back. The WAV will sound exactly like the MP3. The benefit is that it won't lose any more quality during editing, and it works with tools that refuse MP3.
Common questions
Does WAV sound better than the MP3 it came from?
No. It sounds identical. WAV simply stores the decoded audio without further compression.
What sample rate will the WAV use?
44.1 kHz, the CD standard and the rate nearly all MP3s are encoded at.
Why are the WAV files so large?
They're uncompressed, roughly ten times the size of a typical MP3. That's normal.
Can I convert many MP3s at once?
Yes. Add a batch, convert them in one go, and download everything as a ZIP.
