About converting MP3 to FLAC
MP3 is the most universally compatible audio format, playable on every device. FLAC is a lossless format that preserves full audio quality at roughly half the size of WAV. Converting from MP3 to FLAC swaps one for the other without changing the underlying content.
Pick your target bitrate before converting, and you can also drop in a video file to pull out just its audio track.
