M4A is the MPEG-4 audio container format most commonly wrapping AAC audio data. It is Apple's standard for digital music distribution (iTunes Store, Apple Music) and serves as the default audio format across the entire Apple ecosystem. Converting a 3GPP video to M4A extracts the audio track into a metadata-rich container that works seamlessly with iTunes, iPhone, iPad, Apple Watch, and Mac — while also being broadly compatible with Android and Windows.
M4A's advantage over raw AAC files is comprehensive metadata support. An M4A file can store album art, chapter markers, lyrics, artist information, track ordering, and gapless playback flags — making it possible to organize extracted phone audio as a proper music or podcast library rather than a collection of anonymous audio clips.
For anyone using Apple devices, M4A is the path of least resistance. It plays natively everywhere in Apple's ecosystem, benefits from hardware AAC decoding on iOS, and integrates with Siri, HomePod, CarPlay, and AirPlay without any format conversion steps.
FFmpeg extracts the audio stream from the 3GPP container and either stream-copies (if the source is AAC) or transcodes (from AMR) to AAC, packaging the result in an M4A container. The M4A wrapper supports iTunes-style atoms for comprehensive metadata. Common output settings are 128-256 kbps VBR for music-quality content and 64-96 kbps for speech.
Stream copying AAC preserves original quality exactly. Transcoding from AMR to AAC produces a file that sounds identical to the decoded AMR source at appropriate bitrates (64-128 kbps). M4A as a container adds no quality impact — it simply wraps the audio data with metadata support.
