About M4A and MP3
M4A is an MP4-based audio format (usually AAC) used by Apple devices and iTunes.
MP3 is a lossy compressed format with small file sizes and near-universal support, ideal for music and podcasts.
Note: MP3 is a lossy format. Converting from another lossy format re-compresses the audio, so use a higher bitrate to preserve quality.
