MTS to AU Converter

Convert MTS files to AU. Free, without uploading.

This tool converts MTS files to AU. AVCHD camcorder video.

Sun/NeXT audio. Only the audio of the MTS video is kept and saved as AU; the picture is dropped. AU is lossless, so the audio keeps the quality it has in the MTS file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the MTS video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the AU file.
