Why it becomes an MP3

WAV is uncompressed audio: exact, but big, about 10 MB per minute of CD-quality stereo. It's the format to edit in.

WAV is lossless, so it can't get much smaller and stay WAV. Saving it as MP3 at a lower bitrate is what shrinks it: often 10 to 20 times smaller.

A one hour recording at 64 kbps is about 28 MB.
