How much smaller
Stereo WAV at CD quality runs roughly 10 MB per minute. MP3 at 192 kbps is about 1.4 MB per minute, around a seventh of the size, and for most people on most equipment it is indistinguishable from the original.
For voice recordings, 96 kbps mono halves it again with no meaningful loss. Set channels to mono on the audio converter if the source is a single microphone.
Common questions
Which bitrate should I use?
192 kbps for music, 96 to 128 for speech. 320 is rarely worth double the size.
Is anything lost?
Yes, MP3 is lossy by design. Keep the WAV if the file is a master you will edit again.
