About the TTA format

TTA (True Audio) is a no-frills real-time lossless compressor: simple 32-bit crypto-free checksums, multi-threadable encoding and IDs at both frame and file level. It filled the lossless niche on slow connections and in Russian archive communities where FLAC arrived late.

Decoding is near-instant and lossless, so converting TTA to FLAC or MP3 costs nothing in fidelity — the audio is identical, the compatibility is finally universal.

+ Strengths

  • ✓Real-time speed on modest hardware
  • ✓Simple, well-documented container
  • ✓Error-tolerant frame structure

! Limitations

  • −Compression ratios behind modern codecs
  • −Ecosystem largely inactive
  • −Tagging support is weak

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 TTA to AU?

Converting makes sense where the strengths of AU meet what TTA cannot give you. Simple, lossless sample storage Meanwhile Compression ratios behind modern codecs One pass through the converter above puts your file on the right side of that trade-off.

Frequently asked questions

Is this TTA 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 TTA 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.

Can I convert a whole folder of TTA 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.
