Why convert MP3 to WAV

Some software and hardware only accept WAV: certain samplers, older CDJs, broadcast systems, video editors and upload forms.

This converter decodes the MP3 and writes uncompressed PCM WAV at the bit depth and sample rate you choose.

DAW and sampler imports

Load a reference or sample where MP3 isn't supported.

DJ and broadcast gear

Play files on systems that require WAV.

Video editing

Avoid timing drift some editors have with MP3.

Will MP3 to WAV improve the sound?

No. Converting MP3 to WAV does not restore the detail removed when the MP3 was made. The WAV sounds the same as the MP3, it is just larger and easier for some tools to use.

Distributors can often tell when a WAV started life as an MP3. If you need a master for release, export a WAV from your original project instead.

MP3 to WAV - frequently asked questions

Does converting MP3 to WAV increase quality?

No. It changes the container and makes the file uncompressed, but lost detail can't come back.

Can I send an MP3-to-WAV file to my distributor?

Avoid it. Export a real WAV from your project. Upsampled MP3s can be flagged and will sound like the MP3.

Which bit depth should I choose?

16-bit is enough for an MP3 source. Choose 24-bit only if your software requires it.

Is the MP3 uploaded anywhere?

No. Everything runs on your device.

Why is the WAV so much bigger?

WAV stores audio uncompressed, about 10 MB per minute at 16-bit / 44.1 kHz stereo.
