Need Audio from Your Camcorder Videos?

You recorded important footage with your HD camcorder-a wedding speech, an interview, a concert. Now you need just the audio, and you want it to work seamlessly on Windows devices.

MTS files are AVCHD video containers commonly produced by Sony and Panasonic camcorders. They contain high-quality audio (usually Dolby AC-3 or PCM), but extracting it requires conversion. WMA (Windows Media Audio) is Microsoft's native format, optimized for Windows Media Player and Windows-based devices.

Our converter extracts the audio track from your MTS files and encodes it as WMA-ready for playback on any Windows PC, tablet, or compatible device.

How to Convert MTS to WMA

Upload your MTS file - Drag and drop or click to select your camcorder footage
Choose WMA output - Select WMA as your target audio format
Download your audio - Get your extracted audio file, ready for Windows

The entire process happens in your browser. No software installation, no account creation required.

Why Convert MTS to WMA?

While you can extract audio to more universal formats like MP3, WMA offers specific advantages for Windows users:

Native Windows support - WMA plays in Windows Media Player without additional codecs
Better compression at low bitrates - WMA delivers acceptable quality at 64 kbps, where MP3 may sound thin
Microsoft ecosystem integration - Seamless with Windows apps, libraries, and devices
Smaller file sizes - WMA achieves similar quality to MP3 at lower bitrates, saving storage

In our testing, WMA files at 128 kbps sounded comparable to MP3 at 160 kbps for voice and dialogue content-the type most commonly recorded with camcorders.

Common Use Cases

Preserving Wedding Speeches

Camcorder footage from ceremonies often captures speeches, vows, and toasts. Extracting the audio as WMA lets you create audio-only keepsakes that play reliably on family Windows PCs without video player requirements.

Interview Transcription

Journalists and researchers often record interviews on HD camcorders for video quality. Converting to WMA provides lightweight audio files for transcription software and playback during the writing process.

Music Performance Archives

Recorded a concert or recital? Extract the audio for an audio-only archive. WMA's efficient compression keeps file sizes manageable for large music libraries.

MTS vs WMA: Understanding the Formats

MTS (MPEG Transport Stream) is a container format used by AVCHD camcorders. It wraps H.264 video with either Dolby AC-3 or uncompressed PCM audio at high bitrates-typically recorded at 48 kHz for professional quality.

WMA is purely an audio format developed by Microsoft in 1999. It supports bitrates from 5 to 384 kbps and sampling rates from 8 kHz to 96 kHz. For most extracted camcorder audio, 128-192 kbps WMA provides excellent quality.

The conversion extracts the audio stream from the MTS container and re-encodes it as WMA, discarding the video data entirely.

When to Choose a Different Format

WMA is ideal for Windows-centric workflows, but consider alternatives if:

Cross-platform needed - MP3 works on virtually every device and operating system
Apple devices - Use M4A for native iOS/macOS compatibility
Professional editing - WAV preserves full quality for audio editing software

For Windows-only playback or when file size matters more than universal compatibility, WMA remains a solid choice.

Works in Any Browser

Convert MTS to WMA directly from:

Windows, Mac, Linux, Chromebook
Chrome, Firefox, Safari, Edge
Tablets and mobile devices

No plugins, no downloads-just upload and convert.

Pro Tip

AVCHD camcorders typically record audio at 48 kHz with Dolby AC-3 encoding. When converting to WMA, this high-quality source means even moderate bitrate settings produce excellent results for speech and ambient audio.

Common Mistake

Converting to WMA for cross-platform sharing. WMA works great on Windows but causes playback issues on Mac, Linux, and mobile devices. Use MP3 if recipients have mixed devices.

Best For

Windows-only playback scenarios: archiving interview audio on a Windows PC, creating speech excerpts for Windows presentations, or extracting camcorder audio for Windows Media Player libraries.

Not Recommended

Don't use WMA if you plan to share files with Mac or Linux users, edit in professional DAWs (which prefer WAV), or need guaranteed playback on any device (use MP3).

Frequently Asked Questions

MTS is the file extension for AVCHD video, a format developed by Sony and Panasonic for HD camcorders. It contains H.264 video and high-quality audio (typically Dolby AC-3 or PCM) in an MPEG Transport Stream container.

WMA (Windows Media Audio) is Microsoft's audio compression format, introduced in 1999. It's optimized for Windows devices and can deliver good quality at lower bitrates than MP3, making it efficient for storage.

There's some quality reduction since WMA is a lossy format. However, at 128-192 kbps, the difference from the original camcorder audio is minimal for most listeners, especially for speech and voice content.

WMA has limited support on Apple devices. VLC can play WMA on Mac, but for iPhone/iPad, you'll need a third-party app. For Apple compatibility, consider converting to MP3 or M4A instead.

Conversion time depends on your file size and internet speed. A typical 10-minute MTS camcorder clip converts to WMA in under a minute on most connections.

Yes. Upload multiple MTS files and convert them all to WMA in a single batch. No need to process them one at a time.

We use a quality-optimized bitrate that balances file size with audio fidelity. For most camcorder audio, this produces excellent results suitable for both playback and archiving.

No. This conversion extracts only the audio track-the video is discarded. Keep your original MTS file if you need the video later.

WMA offers better quality at lower bitrates, native Windows integration, and smaller files for equivalent quality. Choose it when your playback will primarily happen on Windows devices.
