Convert WAV to MP3
WAV stores audio uncompressed, which is perfect in a studio and impractical everywhere else — roughly 10 MB per minute. MP3 typically reduces that by 90% with no difference most listeners can hear. Pick a bitrate from 128 kbps for speech up to 320 kbps for music, and trim to just the section you need.
