Free online DTS to AU converter

DTS and AU are both audio file formats, but they serve different purposes and use different encoding methods. DTS (Digital Theater Systems) is a high-quality, often multichannel surround sound format commonly used on DVDs, Blu-rays, and home theater systems. AU is an older audio container format originally developed by Sun Microsystems, often used for simple PCM or compressed audio on Unix-based systems.

What is DTS?

DTS is a compressed digital audio format designed for surround sound playback. It is widely used in cinema and home entertainment because it can preserve high audio quality while supporting multiple channels.

What is AU?

AU is a basic audio file format that stores sound data in a simple structure. It is less common today, but it is still recognized by many audio tools and legacy systems.

Why convert DTS to AU?

Converting DTS to AU may be useful when you need compatibility with older software, Unix audio tools, or systems that support AU more readily than DTS. Since AU is usually simpler and less feature-rich, the conversion may reduce channel count or audio complexity.

Best software for DTS to AU conversion

The best choice is FFmpeg, because it supports both formats and offers precise control over audio conversion. It is reliable, free, and available on Windows, macOS, and Linux. For a graphical option, VLC media player can also convert audio files, though FFmpeg is generally more flexible and better for batch processing.

How to convert DTS to AU with FFmpeg

Use the command line to convert the file:

ffmpeg -i input.dts output.au

If you need to change the audio codec or sample rate for better AU compatibility, you can specify additional options, for example:

ffmpeg -i input.dts -ar 44100 -ac 2 output.au

How to convert DTS to AU with VLC

In VLC, open the file and go to Media → Convert / Save. Add the DTS file, choose a profile that outputs audio, set the destination filename with the .au extension, and start the conversion.

Important notes

• DTS may contain multichannel audio, while AU often works best with simpler audio layouts.
• Some DTS files may require decoding support before conversion.
• Audio quality and channel count may change during conversion depending on the chosen settings.
• Always verify the output in an audio player that supports AU.

Summary

DTS to AU conversion is straightforward with tools like FFmpeg or VLC. If you want the most dependable and flexible solution, FFmpeg is the recommended converter.
