M2TS from Blu-ray discs contains some of the highest-quality consumer audio: DTS-HD Master Audio (lossless), Dolby TrueHD (lossless), LPCM at 24-bit/96 kHz, or standard AC3 at 640 kbps 5.1 surround. WAV (Waveform Audio File Format) stores raw, uncompressed PCM audio in a RIFF container. Converting M2TS to WAV extracts the full audio quality from these premium sources into the most universally compatible, edit-ready format in existence.
WAV is the universal denominator of audio — every audio application, DAW, operating system, and hardware device in existence can handle WAV files. When you need to edit, analyze, or master audio from Blu-ray or camcorder sources, WAV provides an uncompressed starting point that avoids any codec-specific quirks or decoding artifacts. It is the standard exchange format between audio professionals worldwide.
FFmpeg extracts the audio stream from the M2TS transport stream, decodes AC3/DTS/DTS-HD MA/TrueHD/LPCM to raw PCM, and writes it into a WAV RIFF container. Default output matches the source specification: 24-bit/48 kHz for Blu-ray sources (matching Blu-ray's standard audio spec), or 16-bit/48 kHz for AVCHD. Multi-channel content can be written as multi-channel WAV (using WAV's channel mask) or downmixed to stereo. For lossless M2TS tracks (LPCM, DTS-HD MA, TrueHD), the WAV output is bit-identical to the master audio.
From lossless M2TS sources (LPCM, DTS-HD MA, TrueHD), WAV output is bit-perfect — identical to the studio master. From lossy AC3/DTS, WAV perfectly captures the decoded audio. WAV itself introduces zero quality change — it is an uncompressed PCM format. This is the highest-quality audio extraction possible.
