About M4A
M4A is an audio format commonly used by Apple devices and many modern apps. It most often stores AAC-compressed audio, though Apple Lossless (ALAC) can use the same extension. AAC typically delivers strong quality at smaller file sizes than uncompressed WAV.
M4A works well for music libraries, podcasts, and mobile playback. It is a solid choice when you want high-quality audio that still fits comfortably on phones and tablets.
Fun fact: M4A is part of the MP4 family of formats, even though it is used mainly for audio rather than video.
