AU to TTA Converter

Convert AU files to TTA. Free, without uploading.

This tool converts AU files to TTA. Sun/NeXT audio.

True Audio lossless. TTA is lossless, so the audio keeps the quality it has in the AU 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 AU 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 TTA file.
