M2TS files from Blu-ray discs and AVCHD camcorders typically contain multi-channel audio tracks — Dolby AC3 (Dolby Digital) at 640 kbps, DTS at up to 1.5 Mbps, or uncompressed LPCM at 4.6 Mbps for Blu-ray. AAC (Advanced Audio Coding) is the MPEG-4 standard audio codec that delivers excellent quality at low bitrates and plays on virtually every modern device. Converting M2TS to AAC extracts the audio from high-definition video recordings and produces universally compatible audio files.
Extracting AAC audio from M2TS is common for isolating soundtracks from Blu-ray movies, pulling audio from camcorder recordings of concerts or events, and creating compact audio files from multi-gigabyte video content. AAC at 256 kbps delivers near-transparent quality from AC3/DTS sources while being natively supported by every smartphone, tablet, and computer. It is the most efficient lossy format for high-quality audio extraction from M2TS.
FFmpeg reads the M2TS transport stream, identifies the primary audio track (AC3, DTS, DTS-HD, or LPCM), decodes it to PCM, and encodes to AAC using the native or libfdk_aac encoder. Multi-channel content (5.1 or 7.1 surround) can be preserved as multi-channel AAC or downmixed to stereo. For Blu-ray M2TS with multiple audio tracks (e.g., English AC3 + French DTS), the desired track can be selected by stream index. LPCM from Blu-ray is transcoded directly without intermediate decoding since it is already uncompressed.
AAC at 256 kbps stereo provides quality that is very difficult to distinguish from the original AC3/DTS source in blind listening tests. For multi-channel preservation, AAC at 384-512 kbps 5.1 maintains spatial audio quality. Since AC3 at 640 kbps is itself a lossy codec, transcoding to high-bitrate AAC introduces minimal additional artifacts.
