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 VOC format
VOC is the Creative Sound Blaster format — if a DOS game made a sound between 1989 and 1994, it was probably a VOC: 8-bit samples at exotic sample rates, with loop points, silence blocks and hardware-specific appendices that made each card sing differently.
ffmpeg decodes the standard sample blocks and converts VOC to WAV or MP3 — the cheapest time machine for retro-game audio.
+ Strengths
- ✓The DOS gaming era's audio format
- ✓Unique features: loops, silence, transfer blocks
- ✓Simple to decode
! Limitations
- −8-bit/11kHz era fidelity
- −Creative hardware extensions lost on convert
- −Rarely produced after 1995

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