Why Extract AMR Audio from MTS Files?

MTS files from your camcorder contain high-definition video with professional audio tracks. But sometimes you only need the spoken content-an interview, a lecture, or meeting notes recorded on your camera.

AMR (Adaptive Multi-Rate) format is designed specifically for speech. It creates extremely small files while preserving voice clarity, making it ideal for mobile phones and voice-focused applications. If you have MTS files with important spoken content, extracting to AMR gives you portable, lightweight audio.

How to Convert MTS to AMR

  1. Upload your MTS file - Drag and drop or click to select your camcorder footage
  2. Select AMR as output - Choose AMR for speech-optimized, compact audio
  3. Download your audio - Get your extracted voice track ready for mobile use

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

Understanding MTS and AMR Formats

MTS (MPEG Transport Stream) is the format used by Sony, Panasonic, Canon, and JVC HD camcorders. These files contain high-quality video encoded in H.264 or MPEG-2, paired with Dolby Digital, DTS, or uncompressed PCM audio tracks.

AMR was developed specifically for mobile telecommunications. It uses adaptive bitrate encoding that prioritizes human speech frequencies. In our testing, a 10-minute voice recording converts to roughly 1-2 MB in AMR format-compared to 15-20 MB for the same audio in MP3.

This dramatic size reduction makes AMR perfect when storage or bandwidth matters more than music-quality audio.

When MTS to AMR Makes Sense

Interview Recordings

Filmed an interview with your camcorder? Extract just the audio in AMR format for transcription services or easy sharing via messaging apps.

Lecture and Conference Footage

Conference recordings often contain hours of spoken content. Converting to AMR creates manageable files you can store on any device without eating storage space.

Voice Memos from Video

Sometimes you record video when audio would have been enough. Extract the spoken content without keeping the large video file.

Mobile Distribution

Need to share audio with people on basic phones or limited data plans? AMR's tiny file sizes work where larger formats struggle.

What to Expect from the Conversion

AMR is optimized for voice, not music. Here's what that means in practice:

  • Speech sounds clear - Voice frequencies are preserved well
  • Music loses quality - Background music or sound effects won't sound as good
  • Files are tiny - Expect 90% smaller files compared to original MTS audio
  • Mono output - AMR typically produces single-channel audio

For general audio extraction where quality matters more than size, consider MTS to MP3 instead. For voice-specific needs, AMR delivers.

Browser-Based Conversion

Our converter works directly in your web browser:

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

Your files process locally. No uploading to external servers, no waiting in queues.

Pro Tip

AMR works best for spoken content recorded in quiet environments. If your MTS footage has significant background noise or music, the speech-focused compression may produce artifacts. Consider cleaning up audio before conversion or using MP3 for mixed content.

Common Mistake

Using AMR for music or ambient sound recordings. AMR aggressively compresses frequencies outside the speech range, so musical content sounds noticeably degraded. Reserve AMR for voice-only content.

Best For

Interview extraction, lecture recordings, conference footage, and any scenario where you need to share spoken content with minimal file size. Perfect for distribution via messaging apps or email.

Not Recommended

Don't convert to AMR if your MTS footage contains music you want to preserve, or if you need high-fidelity audio for editing. Use MP3, AAC, or WAV for those situations.

Frequently Asked Questions

MTS (MPEG Transport Stream) is a video format used by HD camcorders from Sony, Panasonic, Canon, and JVC. It contains high-definition video with multi-channel audio, typically recorded in AVCHD format.

AMR (Adaptive Multi-Rate) is a speech-optimized audio format developed for mobile phones. It creates very small files by focusing on voice frequencies rather than full-spectrum audio like music.

For speech and voice content, yes. AMR is designed specifically for human voice and preserves clarity well. However, music and complex sounds will lose quality since AMR prioritizes speech frequencies.

Significantly smaller. In our testing, AMR files are typically 80-90% smaller than the equivalent MP3 audio extracted from the same MTS source. A 10-minute recording might be just 1-2 MB.

Yes. AMR was created for mobile phones and plays on most Android devices natively. iPhones may need a third-party app, but many audio players support AMR playback.

Use AMR when file size matters most and your content is primarily speech (interviews, lectures, voice notes). Use MP3 when you want better overall quality and compatibility, especially for content with music.

AMR typically outputs mono audio since it's optimized for voice. If stereo preservation matters, consider converting to MP3 or AAC instead.

Yes. Upload multiple MTS files and convert them all to AMR in a single batch. Each file processes independently.

No. The conversion happens entirely in your browser. Your MTS files stay on your device throughout the process-nothing is uploaded to external servers.
