About MTS to WAV Conversion
WAV (Waveform Audio) is the universal uncompressed audio format supported by every operating system, DAW, and audio application. AVCHD camcorders record audio as either Dolby AC3 (256-640 kbps compressed surround) or LPCM (1536 kbps uncompressed stereo). Converting MTS to WAV extracts the camcorder audio into raw PCM data — the definitive starting point for any audio editing, analysis, or production workflow.
Why Convert MTS to WAV?
When you need to edit camcorder audio in any DAW — Audacity, Pro Tools, Ableton Live, FL Studio, Reaper — WAV is the format that every tool opens instantly without codec negotiation, conversion delays, or compatibility issues. There is no simpler, more universally supported audio format than WAV.
Forensic audio analysts, scientific researchers, and broadcast engineers also require uncompressed WAV for their work because any lossy format introduces artifacts that can interfere with analysis. Extracting AVCHD audio to WAV provides the cleanest possible representation of what the camcorder's microphone captured, limited only by the recording chain's quality.
Common Use Cases
- Extracting camcorder audio for editing in any DAW (Audacity, Pro Tools, Ableton, Logic)
- Preparing camcorder audio for forensic analysis requiring uncompressed format
- Creating broadcast-ready audio masters from event camcorder recordings
- Building sound effect and ambient recording libraries from camcorder audio
- Providing uncompressed audio deliverables from camcorder source material
How It Works
FFmpeg discards video and writes PCM audio to WAV: `-vn -c:a pcm_s16le -ar 48000 -ac 2`. AVCHD natively records at 48 kHz. For LPCM sources, the extraction is bit-perfect (no re-encoding, just container change). For AC3 sources, the 5.1 surround is decoded and optionally downmixed: `-ac 2` for stereo or `-ac 6` for all channels as separate WAV tracks.
Quality & Performance
WAV is uncompressed — zero quality loss during the WAV encoding step. If the MTS contains LPCM audio, the extraction is bit-perfect (identical samples). If the source is AC3, the WAV faithfully preserves the fully decoded surround audio. File sizes are approximately 34 MB per minute for stereo 16-bit/48 kHz.

Tips for Best Results
- 1Keep 48 kHz sample rate to match AVCHD native rate — avoid resampling unless you specifically need 44.1 kHz for CD mastering
- 2For LPCM sources, use -c:a copy to extract without any re-encoding — it is bit-perfect and instant
- 3Apply noise reduction after extraction to remove camcorder motor hum and handling noise
- 4Extract 5.1 surround channels separately if you need to process them individually in a DAW
- 5Use WAV for editing and convert to FLAC when archiving — they are quality-identical but FLAC halves storage requirements
