Need Audio from Your Camcorder Videos?

MTS files from your Sony, Canon, or Panasonic camcorder contain excellent audio, but getting that audio into a usable format can be frustrating. Many editing programs and devices struggle with the AVCHD container format.

Converting MTS to AAC extracts the audio track and delivers it in a universally compatible format. AAC is the audio standard for iTunes, YouTube, and most modern devices. In our testing, audio extraction from a 10-minute MTS file takes under 30 seconds.

How to Convert MTS to AAC

  1. Upload your MTS file - Drag and drop or browse to select your AVCHD video
  2. Select AAC as output - AAC provides excellent quality at smaller file sizes
  3. Download your audio - Your extracted audio is ready for use anywhere

No software installation required. The entire process happens in your browser.

Understanding MTS and AAC Formats

MTS (MPEG Transport Stream) is the file extension used by AVCHD camcorders. It contains high-definition video encoded with H.264 and audio typically encoded as Dolby Digital AC-3 at 48kHz. The format was jointly developed by Sony and Panasonic for consumer HD recording.

AAC (Advanced Audio Coding) was designed as the successor to MP3. It delivers better sound quality than MP3 at the same bitrate, making it ideal for preserving the audio quality from your original recordings. Apple, YouTube, and most streaming services use AAC as their preferred audio format.

Why Extract AAC Instead of MP3?

While MTS to MP3 is popular, AAC offers distinct advantages for quality-conscious users:

  • Better efficiency - AAC sounds better than MP3 at equivalent bitrates
  • Modern standard - Native support on iOS, Android, macOS, and Windows
  • Smaller files - Same quality as MP3 but with reduced file size
  • Streaming compatible - YouTube and Apple Music use AAC natively

For archiving camcorder audio where quality matters, AAC is the smarter choice over MP3.

Common Use Cases

Video Editing Projects

Extract the audio track to edit separately in audio software. Sync refined audio back to your video timeline for professional results.

Interview and Event Recording

Camcorder audio from interviews, speeches, or lectures can be extracted and shared as standalone audio files or podcasts.

Music and Performance Capture

If you recorded a concert or musical performance, extract the audio for listening without needing the video.

Archiving Family Memories

Preserve the audio from important events separately. Voice recordings of loved ones can be more accessible as audio files.

What to Expect

Our converter extracts audio at high quality settings by default. The resulting AAC file maintains the clarity of your original camcorder recording while being compatible with virtually any device or application.

File sizes depend on duration - expect roughly 1MB per minute of audio at standard quality settings. A typical 30-minute camcorder clip produces an AAC file around 30MB.

Works on Any Device

Convert MTS to AAC directly in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android tablets

No downloads or installations. Your files stay on your device throughout the conversion process.

Pro Tip

MTS files often contain high-quality Dolby Digital audio at 48kHz. Converting to AAC at 256kbps or higher preserves this quality while giving you a universally compatible format for editing or playback.

Common Mistake

Users sometimes convert to MP3 out of habit when AAC would give them better quality at smaller file sizes. Unless you specifically need MP3 compatibility for older devices, AAC is the better choice.

Best For

Extracting interview audio, preserving event recordings, or creating audio archives from camcorder footage where quality matters more than maximum compatibility.

Not Recommended

If you need audio for professional broadcast or DAW editing, consider converting to WAV or FLAC instead. AAC is lossy and may not meet broadcast standards.

Frequently Asked Questions

MTS is the file extension for AVCHD video files recorded by HD camcorders from Sony, Panasonic, Canon, and other manufacturers. It contains H.264 video and typically Dolby Digital audio in a transport stream container.

Minimal quality loss occurs during conversion. We extract at high bitrate settings to preserve the clarity of your original camcorder recording. Most users cannot distinguish between the original and converted audio.

AAC provides better sound quality than MP3 at the same file size. It's the modern standard used by Apple, YouTube, and streaming services. For archiving quality audio, AAC is the superior choice.

Yes. Upload several MTS files and convert them all to AAC in a batch. This is especially useful when processing footage from an entire event or trip.

Conversion is fast - typically under 30 seconds for a 10-minute video. Larger files take proportionally longer, but the process is still much faster than real-time.

Nearly all modern devices support AAC natively: iPhones, iPads, Android phones, Mac, Windows PC, and most car audio systems. AAC is one of the most universally compatible audio formats.

No installation required. The converter runs entirely in your web browser. Simply upload your MTS file, convert, and download the AAC result.

We use high-quality encoding settings that balance file size with audio fidelity. The output preserves the original audio quality while remaining efficient for storage and streaming.

The converter extracts the complete audio track. For trimming specific sections, use an audio editor after conversion. Free options like Audacity work well with AAC files.
