M2TS to WAV Converter

How to Convert M2TS to WAV Online

1. Upload Your M2TS File: Drag and drop or click "Add Files" to select your.m2ts video. M2TS is the BDAV transport-stream container used by Blu-ray discs and AVCHD camcorders (Sony, Panasonic, Canon). Batch upload is supported.
2. Pick Audio Channel: Default is Original (keeps the source layout — typically 2.0 stereo for AVCHD, 5.1 for Blu-ray). Choose Stereo to downmix a 5.1 surround track for headphones or stereo speakers, or Mono to collapse to a single channel for voice work and podcasts.
3. Set Audio Sample Rate (Optional): Default is Original. Pick 44100 Hz for CD-burning workflows, 48000 Hz to keep the standard Blu-ray/AVCHD rate, or step down to 24000/16000/12000/8000 Hz for voice-only output where smaller files matter.
4. Trim (Optional) and Convert: Switch Trim to "Trim" and enter Start Time and Duration in seconds or HH:MM:SS.sss to grab a single scene. Click Convert — your WAV downloads from the browser, no sign-up and no watermark.

Why Convert M2TS to WAV?

M2TS (also called BDAV MPEG-2 Transport Stream) is the wrapper that Blu-ray discs and AVCHD camcorders use to multiplex H.264 video with audio streams encoded as Dolby Digital (AC-3), DTS, linear PCM, or — on higher-end discs — Dolby TrueHD and DTS-HD Master Audio. WAV strips everything except the audio and stores it as uncompressed linear PCM, the same encoding used on Audio CDs. The conversion is useful when:

• Editing Blu-ray or AVCHD audio — Audacity, Pro Tools, Logic Pro, Reaper, and Adobe Audition all import WAV with no decode step, so edits stay sample-accurate.
• CD authoring — Red Book audio CDs require 44100 Hz / 16-bit stereo PCM; WAV is the native input for Nero, ImgBurn, and Apple Music's "Burn Disc" flow.
• Lossless archival — Decoding AC-3 or DTS to PCM once and storing the WAV avoids generation loss if you re-edit later. For even smaller lossless files, see M2TS to FLAC.
• Sampling for music production — DAWs treat WAV as the canonical sample format; dropping a clip into Ableton or FL Studio works without conversion.
• Speech-to-text and transcription — Whisper, Otter, and Rev all accept 16 kHz / 16-bit mono WAV; downmix to Mono in step 2 and drop the sample rate in step 3.
• Apple-native workflows — If you're on macOS and editing in Final Cut or Logic, AIFF is byte-equivalent to WAV with a different byte order; use M2TS to AIFF instead.

Frequently Asked Questions

Why is the audio codec dropdown not shown?

WAV on xconvert is fixed at PCM 16-bit Little Endian (PCM_S16LE) — the same encoding used on Audio CDs and accepted by every DAW and Blu-ray authoring tool. There's nothing to choose because every other "WAV codec" (PCM_S24LE, PCM_MULAW, ADPCM) is a niche variant; if you need 24-bit float for a mastering session, render from your DAW after the WAV import.

Will a 2-hour Blu-ray movie fit in a single WAV?

Probably not. Standard WAV uses a 32-bit RIFF size field that caps files at 4 GiB. At 44.1 kHz / 16-bit stereo (~10 MB/min), you hit the cap at roughly 6.8 hours, so a 2-hour film fits — but a 2-hour 5.1 surround source at 48 kHz / 24-bit can exceed it. If your file hits the cap, downmix to stereo in step 2 or split with Audio Cutter and re-join.

Should I extract as 44100 Hz or 48000 Hz?

Pick 48000 Hz if the output is going back into a video timeline (Premiere, DaVinci Resolve, Final Cut all default to 48 kHz to match video standards). Pick 44100 Hz if you're burning an Audio CD — Red Book requires it. Sample-rate conversion is lossy at the dithering stage, so match the destination.

Does the conversion preserve 5.1 surround?

If you leave Audio Channel on Original and the M2TS source contains a 5.1 stream, the output WAV is multi-channel. If you pick Stereo, the converter downmixes using the standard ITU-R BS.775 matrix (Lt/Rt) and you lose surround positioning permanently — keep an Original copy if you might re-edit later.

Why does my AC-3 source sound the same as the original — isn't WAV "lossless"?

WAV is lossless relative to its input. If the input is already lossy AC-3 or DTS, decoding to PCM doesn't recover detail that was discarded at the original encode. The benefit is that further edits stay lossless, since PCM doesn't re-quantize. For a TrueHD or DTS-HD MA source, the WAV is bit-identical to the studio master.

How long does conversion take?

The entire process runs on our servers — files don't leave your machine for re-encoding the way they do on FFmpeg-on-server tools. Throughput is bound by audio demuxing speed; a 4 GB M2TS typically converts in under a minute on a modern laptop.

Can I extract just one scene?

Yes. Switch Trim to "Trim", enter the Start Time (e.g. 00:45:12.500) and Duration (e.g. 90 seconds or 00:01:30). Only that segment is decoded and written, which also keeps the output under the 4 GiB WAV cap.

What about MP3, AIFF, or FLAC instead of WAV?

WAV is the universal raw-PCM choice. For lossy-but-tiny output, use M2TS to MP3 — a 90-minute soundtrack drops from ~600 MB WAV to ~85 MB MP3 at 128 kbps. For Apple-native uncompressed audio use M2TS to AIFF. For lossless compression at roughly half the size of WAV, use M2TS to FLAC.

Are uploads private?

files are processed on our servers and deleted automatically after a few hours and aren't kept on a server after conversion. There's no account requirement, no watermark on the output, and no upload size charge.
