WAV versus MP3 sizes
WAV stores uncompressed audio, so size depends only on length: about 10 MB per minute for 44.1 kHz 16-bit stereo. MP3 at 192 kbps uses about 1.4 MB per minute regardless of content.
- 3-minute song: about 30 MB as WAV, about 4.3 MB as MP3.
- 1-hour recording: about 600 MB as WAV, about 86 MB as MP3.
When to keep the WAV
MP3 is lossy. 192 kbps sounds transparent to most listeners, but if you're still editing, mixing or mastering, keep the WAV as your master and make MP3s for sharing.
