Convert 3GPP to M4A — Free Online Converter

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.
