M2TS to WMA Converter

M2TS to WMA — Should You Extract the Audio to WMA?

This tool pulls the audio track out of an M2TS file — a Blu-ray rip or an AVCHD camcorder clip — and saves just the sound as WMA, discarding the video. The short answer on the target format: pick WMA only if something on the Windows side specifically needs a .wma file. For anything you'll edit, publish, or play on a phone, extract to MP3 is more portable, and if your source carries 5.1 surround you want AAC instead — WMA Standard can only hold two channels, so it flattens surround to stereo every time.

M2TS Source Audio vs WMA — Side by Side

The M2TS container (BDAV MPEG-2 Transport Stream) can wrap several different audio codecs depending on where the file came from. What survives the trip to WMA depends entirely on which one your file holds.

When to Pick WMA

• A legacy Windows program, an older Windows Media Player library, or a Windows-era device specifically asks for .wma.
• The source is already a stereo AC-3 or LPCM track, so nothing multichannel is being lost.
• You want one self-contained Windows-native audio file and don't need it to play on Apple or mobile devices.

When to Pick MP3 or AAC Instead

• You want the soundtrack to play almost anywhere — phones, the Apple Music app, web players. WMA never spread far beyond Windows, so extract to MP3 for the safe default.
• Your M2TS is a Blu-ray rip with a 5.1 or 7.1 mix you want to keep. Extract to AAC, which carries multichannel audio; WMA Standard would downmix it to stereo.
• You'd rather keep the picture too — convert M2TS to MP4 re-encodes both streams into one playable file.

WMA vs MP3 vs AAC as an Extraction Target

All three are lossy, so none can improve on the M2TS source audio — the difference is compatibility and how many channels survive.

How to Convert M2TS to WMA

1. Upload Your M2TS File: Drag and drop your .m2ts (Blu-ray) or .mts (camcorder) clip onto the page, or click "+ Add Files". Queue several clips to extract them in one batch with the same settings.
2. Pick a Quality Preset: Open Advanced Options and choose a Quality Preset under File Compression — Highest down to Lowest. For an extracted soundtrack, the upper presets are already CD-grade.
3. Set the Bitrate and Channels (optional): Switch to Constant Bitrate for a predictable file size or Custom Bitrate to type an exact rate, and leave Audio Channel and Audio Sample Rate on "Original" to keep what the source recorded. Use Trim to keep only part of a long recording.
4. Convert and Download: Click "Convert" and download your .wma file individually or as a ZIP. No sign-up, no watermark.

Frequently Asked Questions

Does this keep the video, or just the audio?

Just the audio. This is an extraction: the H.264, MPEG-2, or VC-1 video inside your M2TS is discarded and only the soundtrack is written out as a WMA file. If you want to keep the picture too, convert M2TS to MP4 instead, which re-encodes both the video and audio into a single playable file.

What audio does an M2TS file actually contain, and does that affect WMA quality?

It depends on where the M2TS came from. AVCHD camcorder clips almost always carry Dolby AC-3 (Dolby Digital), which is already lossy — so extracting to WMA is a lossy-to-lossy transcode that can match but not exceed the source. Blu-ray rips may instead hold DTS, Dolby TrueHD, DTS-HD, or uncompressed LPCM. When the source is lossless (LPCM, TrueHD, DTS-HD Master), extracting to WMA is a clean first-generation encode. Either way, keep the WMA bitrate at or above the source to keep any second-generation loss minimal.

Can WMA keep my M2TS file's 5.1 or 7.1 surround sound?

No. M2TS audio can carry up to 5.1 (AC-3, DTS) or even 7.1 (Dolby TrueHD, DTS-HD), but the standard WMA codec is limited to two channels, so any surround track is downmixed to stereo during extraction. There is no surround-capable WMA output here. If preserving more than two channels matters — common with Blu-ray rips — extract to AAC instead, which supports multichannel audio.

Is a .mts file the same as .m2ts for this conversion?

Yes — they're the same BDAV container. .MTS is the 8.3 short-filename form an AVCHD camcorder writes to its card; .m2ts is the long-filename form used on Blu-ray and after you import a camcorder clip to a computer. The bytes are the same, so the audio extraction is identical whether your file ends in .mts or .m2ts. For the camcorder-folder workflow specifically, AVCHD to WMA walks through where the clips hide on the card.

Why is the WMA no smaller or better than I expected?

WMA Standard is a lossy codec, so it trades some quality for size like MP3 or AAC. If your source was already lossy AC-3 or DTS, the WMA can only approximate it — encoding above the source bitrate won't recover detail the original codec already discarded, it just avoids adding a second round of loss. If your source was LPCM, you'll get a clean encode, and a higher Quality Preset or bitrate keeps it closer to the master.

Should I extract to WMA at all, or pick MP3 or AAC?

Pick WMA only when something on the Windows side specifically needs a .wma file. WMA dates to 1999 and never spread far beyond the Windows ecosystem, so Apple's Music app, most phones, and many web players don't handle it. For a soundtrack you'll edit, publish, or play across devices, M2TS to MP3 or M2TS to AAC is the more compatible choice — AAC also being the one to use if you want to keep surround.

What WMA bitrate should I choose for an extracted soundtrack?

For a stereo track, the Highest or High Quality Preset (roughly 192 kbps and up) keeps the extract close to the source; drop toward the lower presets only when you need a smaller file and can accept audible compression. Because the audio inside an M2TS is already lossy AC-3 or DTS, setting the WMA bitrate above the original recovers nothing — it just avoids adding a second round of loss on top.

How are my files handled, and is there a size limit?

Your M2TS file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. In our testing, the main practical limit is upload size and time rather than the extraction itself: an M2TS carries full HD video alongside the audio, so a long Blu-ray title or recording can take a while to upload even though pulling out the soundtrack is quick.
