Convert MP3 to WAV

MP3 is lossy and WAV is not, but that doesn't work backwards - whatever the MP3 threw away stays gone, and WAV just stores the result uncompressed at roughly ten times the size. Worth doing before editing, since every MP3 re-save loses a little more.

What is MP3?

The format that made digital music portable, and thirty years on it's still the safest bet that a file will simply play - any device, any car, any decade-old bit of hardware. It's lossy, its patents expired in 2017, and no browser has ever been able to write one, which is why encoding it here needs LAME.

What is WAV?

Uncompressed audio, roughly 10MB a minute, and the format every piece of audio software will accept without complaint. Nothing is compressed and nothing is lost, which makes it the right thing to edit and the wrong thing to email.
