About WAV to MP3
WAV files store sound without compression, so a few minutes can take tens of megabytes. That's too big for email and slow to upload. As MP3 the same recording is often ten times smaller.
Pick 320 kbps to keep music close to the original, or 128 kbps for speech. The WAV is read and the MP3 encoded on your device.
Most WAV files work: recordings from voice recorders, exports from audio editors and tracks ripped from CDs, in mono or stereo. The MP3 keeps the same length and the same number of channels, so a stereo recording stays stereo.
Keep your WAV files if you might edit the recording again later: every MP3 is a slightly reduced copy, and editing and saving an MP3 repeatedly adds up. For sharing, uploading and listening on the go, the MP3 is the better file. Several WAV files at once download together as a ZIP.
