Convert AU to DTS

Fast, free, and secure AU to DTS conversion. No registration required.

Transform your au files into dts format with a single click. Every conversion runs in your browser, guaranteeing privacy. The input AU Audio format from Sun Microsystems handles Unix system sounds, telephony and basic audio processing, while the output DTS Audio by DTS Inc. is built for Blu-ray discs, home theater systems and cinema audio. AU Audio files typically can be quite large, while DTS Audio output is efficiently compressed for practical file sizes. No signup, no software download, no file size limits — just drag, convert and download.

When Should You Convert AU to DTS?

There are strong reasons to convert AU to DTS:

Editing flexibility: DTS Audio files can be opened in a wider range of editing software, giving you more options for further modifications.

Collaboration ease: Team members and collaborators are more likely to have software that opens DTS Audio natively, reducing compatibility friction.

Smaller file size: Lossy compression in DTS Audio often produces significantly smaller files than AU Audio, saving storage space and bandwidth.

Faster loading: DTS Audio files decode faster on most systems, reducing wait times when opening or streaming content.

Legacy system support: DTS Audio is backward-compatible with older systems that may not support newer or proprietary formats like AU Audio.

AU to DTS Quality Analysis

Supports mu-law, A-law and linear PCM encoding When this data is re-encoded into DTS Audio, DTS-HD Master Audio: lossless extension up to 24.5 Mbps Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Xonvert maintains data integrity across the format boundary. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. DTS Audio's compression algorithm is highly efficient — expect output sizes 2-10x smaller than uncompressed data.

Audio conversion from AU Audio to DTS Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Moving from lossless AU Audio to lossy DTS Audio reduces file size dramatically. At typical quality settings (128-256 kbps), the compression is psychoacoustically transparent — most listeners cannot distinguish the output from the original. Sample rate, bit depth, and channel layout are preserved when supported by the target format.

Compression trade-off: Your lossless AU source retains all original data. Converting to lossy DTS will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.

Bitrate consideration: For lossy DTS output, Xonvert defaults to a high bitrate setting that preserves audio transparency. You can adjust the bitrate in the settings panel — higher values mean better quality but larger files.

What You Need to Know About AU to DTS

Can I convert password-protected AU files?
Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.
Can I convert multiple AU files at once?
Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.
What's the maximum number of files I can convert at once?
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose DTS over other formats?
DTS Audio offers immersive 5.1 and 7.1 surround sound for home theater. It's widely used for Blu-ray discs, home theater systems and cinema audio, making it an excellent choice for most audio needs.
Will my AU file be deleted after conversion?
No. Your original AU file is never modified or deleted. Xonvert creates a separate DTS copy — your source file remains untouched.
What audio quality settings should I use?
For music, use 256 kbps or higher. For voice/podcast, 128 kbps is sufficient. Lossless output preserves everything.
Does this work on my phone or tablet?
Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.
