TTA to AU Converter

Convert TTA files to AU. Free, without uploading.

This tool converts TTA files to AU. True Audio lossless.

Sun/NeXT audio. AU is lossless, so the audio keeps the quality it has in the TTA 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 TTA file, 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.
