MOV files from iPhones, iPads, and Mac applications store audio as AAC-LC, HE-AAC, or Apple Lossless (ALAC) alongside the video track. AAC (Advanced Audio Coding) is the MPEG-4 standard audio codec and Apple's preferred audio format since iTunes launched in 2003. Converting MOV to AAC extracts just the audio layer from your QuickTime video files, discarding the video track entirely.
Extracting AAC from MOV is the most common way to get audio from iPhone recordings, FaceTime calls saved to disk, QuickTime screen recordings with voiceover, and Mac-based podcast recordings captured in QuickTime Player. The audio extraction produces universally compatible files playable on every smartphone, computer, and car stereo.
Since most MOV files already contain AAC-encoded audio, the extraction can often be done as a stream copy — no re-encoding required — preserving the original quality bit-for-bit.
FFmpeg reads the MOV container's track atoms, identifies the audio track (typically track 2), and either copies the AAC bitstream directly (-c:a copy) when the source is AAC-LC/HE-AAC, or transcodes ALAC/PCM audio to AAC using the native FFmpeg encoder or libfdk_aac. The output is an ADTS-wrapped AAC file. iPhone MOV files since iOS 7 use AAC-LC at 44.1 kHz stereo, making stream copy the default path.
When the MOV already contains AAC audio (the common case for iPhone recordings), extraction is bit-perfect — zero quality loss. If the source uses ALAC or PCM, transcoding to AAC at 256 kbps produces near-transparent quality. For voice recordings, even 128 kbps AAC is indistinguishable from the original.
