TAK to AU Converter
Processing entirely on your device — large files may take a moment.
Tom's lossless Audio Kompressor and Sun Microsystems Audio exist for different jobs: TAK is a German high-ratio lossless codec — close to Monkey's Audio ratios with much faster decoding. Converting AU to WAV preserves the samples in a format every modern tool reads.
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.

About the TAK format
TAK (Tom's lossless Audio Kompressor) chases the best ratio-per-decode-speed point: it compresses close to Monkey's Audio while decoding several times faster, and its integer-only decoder is unusually robust against bit errors — an audiophile favorite in the 2000s Windows world.
The official encoder is Windows-only, which froze the ecosystem; ffmpeg reads TAK files losslessly, so converting to FLAC unlocks them for every other platform and player.
+ Strengths
- ✓Near-APE ratios, much faster decode
- ✓Very robust against bit errors
- ✓Pipes with cuesheets for albums
! Limitations
- −Windows-only official encoder
- −Development is slow/inactive
- −Few converters besides ffmpeg
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 TAK to AU?
There is a concrete reason this conversion exists: Windows-only official encoder 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 TAK 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 TAK 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.
Can I convert a whole folder of TAK files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
Will converting TAK to AU reduce audio quality?
If AU is lossless, the output contains everything the TAK 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.
