WAV vs MP3, in plain terms
WAV is uncompressed: every sample of the sound is stored, which is why a minute of CD-quality stereo WAV is about 10 MB. MP3 throws away the parts of the sound people don't hear well, so the same minute at 192 kbps is about 1.4 MB.
For voice, like podcasts and voiceovers, 128 kbps sounds clean. For music, 192 kbps is a good default and 320 kbps is the most MP3 can do. Keep the WAV if you'll edit the sound again: every MP3 conversion loses a little more.
