Why turn WAV into MP3
WAV stores audio uncompressed, about 10 MB for every minute of stereo sound. An MP3 at 192 kbps takes roughly 1.4 MB a minute, small enough to email, upload to a website or keep hundreds of tracks on a phone.
It's the usual last step after recording or mixing: keep the WAV as your master and share the MP3.
Quality settings for WAV to MP3
320 kbps keeps music closest to the WAV master. 192 kbps suits podcasts, demos and most listening. 128 kbps is plenty for speech and keeps files smallest.
Going the other way? MP3 to WAV turns an MP3 back into WAV for editing software. For a walkthrough of other methods, read the WAV to MP3 guide.
