    Good to know

    • M4A usually contains lossy AAC audio; converting to WAV gives you an uncompressed, edit-ready copy but can’t restore detail lost in the original AAC compression.
    • WAV files are large — about 10 MB per stereo minute at CD quality — because they’re uncompressed.
    • WAV is the preferred format for audio editors and professional tools.
