About the AC3 format
AC3 (Dolby Digital) is the surround format of the DVD era and still the standard audio track on Blu-rays and broadcast TV. It carries 5.1 channels at 384–640 kbps — built to make home theatre rumble. Extracted from discs or remuxed downloads, .ac3 files are common on everyone's drive.
Phones and most editors do not decode it. The practical move is conversion: MP3 for listening, WAV when the audio is destined for editing. Both keep the mix you know — just in a format every device handles.
+ Strengths
- ✓True 5.1 surround from disc sources
- ✓The DVD/Blu-ray audio standard
! Limitations
- −Almost no mobile or web support
- −Lossy — downmixing loses the surround image
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

Frequently asked questions
Is this AC3 to TTA 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 AC3 to TTA?
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 AC3 to TTA reduce audio quality?
If TTA is lossless, the output contains everything the AC3 file contains — no further loss is added. If TTA 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.
