    Good to know

    • M4A files usually contain AAC audio, which is slightly more efficient than MP3 at the same bitrate but less universally supported.
    • Because both AAC and MP3 are lossy, converting between them re-compresses the audio; encoding at 192 kbps keeps the quality difference inaudible to most listeners.
    • MP3 works on older cars, hardware players, and apps that reject M4A/AAC files.
