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

Frequently asked questions
Is this AVR 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 AVR 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 AVR to VOC reduce audio quality?
If VOC is lossless, the output contains everything the AVR 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.
