DTS to AU Converter
Processing entirely on your device — large files may take a moment.
Converting AU to WAV preserves the samples in a format every modern tool reads. If your files are still in DTS format, this page is the shortcut: DTS is the competitor surround format to Dolby Digital, common on Blu-ray discs and remuxed movie files.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How DTS compares to AU

| Quality | Up to 1.5 Mbps surround | Mono voice-grade (µ-law) |
| Compatibility | AV receivers, Blu-ray | Legacy Unix tools |
| Best for | Movie soundtracks | Old system sounds and recordings |

About the DTS format
DTS is Dolby Digital's rival: the other surround format licensed for DVDs and Blu-rays, running at higher bitrates (up to 1.5 Mbps core) for a fuller soundstage. Movie rips and remuxes frequently carry DTS tracks, which is why so many files quietly refuse to play on phones.
Conversion to MP3 or WAV is the way out. Editors will thank you for the WAV; headphones-and-commute listeners will never hear the difference MP3 makes at reasonable bitrates.
+ Strengths
- ✓High-bitrate surround on Blu-ray sources
- ✓Widely present in movie files
! Limitations
- −Mobile/web playback almost nonexistent
- −Large compared to lossy stereo
About the AU format
AU is Sun Microsystems' audio format from the Unix workstation age: a small header followed by µ-law (or PCM) samples. Java's applet era shipped it everywhere, and old Unix sound tooling still emits it.
Modern players increasingly skip it. Converting AU to WAV preserves the samples bit-for-bit while moving the file into universal territory — the standard rescue path for system sounds and old recordings.
+ Strengths
- ✓Simple, lossless sample storage
- ✓Native to old Unix/Java tooling
! Limitations
- −µ-law flavor sounds dated and mono
- −Dropped by modern players
Why convert DTS to AU?
There is a concrete reason this conversion exists: Mobile/web playback almost nonexistent AU sidesteps that — Simple, lossless sample storage If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this DTS to AU converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for DTS to AU?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Will converting DTS to AU reduce audio quality?
If AU is lossless, the output contains everything the DTS file contains — no further loss is added. If AU is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
