What is MP3?
MP3 is the world's most widely supported audio format. It uses perceptual compression to shrink files dramatically while keeping the sound close to the original for most listeners.
Why convert WAV to MP3?
WAV files are huge. Converting to MP3 makes them small enough to email, upload, or store on a phone, and MP3 plays on virtually every device and app in existence.
Quality notes
We encode with LAME at high quality (VBR ~190 kbps), a transparent setting for most music and speech. Files end up roughly a tenth of the WAV size.
