Convert WAV to MP3

The size drop is the whole point - uncompressed audio runs about 10MB a minute, and a good MP3 is a tenth of that. Encoded here with LAME, the same encoder most music software has used for twenty years.

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.

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.
