Reasons for keeping lossless audio

• maybe today, you, with current environment cannot hear the difference between 320kbps mp3 and wav.
  • What about tomorrow?
  • What about other people than you? (At least as DJ you should probably care about others)
  • What about a different environment, e.g. new speakers, headphones ...?
  • What about effects that one cannot hear, but are still there?

You can use lossless compression to save disk space while keeping the original audio data. One such lossless audio format is FLAC.
