Fast, secure TTA to VOC conversion. No registration required.
Setup: TTA is the True Audio lossless codec, fast to decode on low-power devices. Goal: an interchangeable VOC. A TTA to VOC transcode is mostly about compatibility, not fidelity. At sensible default bitrates you cannot tell the two apart by ear; what you get is a file that actually opens on the hardware or website you were aiming at. FFmpeg handles the heavy lifting and we stream the result straight back as a download. Context: TTA is the True Audio lossless codec, fast to decode on low-power devices. VOC is the Creative Labs Voice format from the Sound Blaster era.
True Audio Lossless
Source formatTTA (True Audio) is an open-source lossless audio codec that provides real-time lossless compression with hardware-friendly decoding. It achieves compression ratios similar to FLAC while maintaining very low CPU requirements during playback.
Creative Voice
Target formatVOC (Creative Voice) is an audio file format created by Creative Labs for Sound Blaster sound cards. It was a dominant PC audio format in the DOS gaming era, supporting multiple data blocks with different sample rates within a single file.
Why convert TTA to VOC
Moving from TTA to VOC usually buys compatibility or a friendlier file size. For spoken-word content the difference is inaudible; for high-resolution music pick the highest bitrate the VOC codec supports to avoid compounding compression.
HOW TO CONVERT
TTA → VOC
Provide the audio file
Drag the TTA onto the uploader. Files up to 25 MB run on the free tier without registration; paid plans go up to 2 GB.
ffmpeg handles the conversion
Our ffmpeg-based pipeline reads sample rate and channel layout, then writes a matching VOC with ID3 tags intact.
Save the output
Click to download the VOC. Batch uploads are bundled into a ZIP for single-click retrieval.
Common Use Cases
Share across platforms
Send VOC files to anyone without worrying about whether they have the right software for TTA.
Embed in documents
Drop VOC output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
VOC often produces smaller files than TTA for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
TTA vs VOC — Strengths and limitations
What each format does best, and where it falls short.
TTA Strengths
- Lossless bit-exact reproduction.
- Fast, low-memory decoding.
- Open-source reference.
- Cue-sheet support.
Limitations
- Compression ratio worse than FLAC.
- Niche tooling.
- Hardware support died with 2000s DAP era.
VOC Strengths
- Retro-gaming archive format.
- Supported by DOSBox and SoX.
- Block-based structure allows streaming.
Limitations
- Legacy — no new content since mid-1990s.
- Limited sample rates (up to 44.1 kHz).
- No metadata.

- Short speech sample 30-300 KB
Quality & Compatibility
Sample rate, channel layout and bit depth are preserved by default: a 44.1 kHz stereo TTA becomes a 44.1 kHz stereo VOC. Metadata — title, artist, album, cover art — travels where both formats support it. Protected DRM content cannot be converted legally and is rejected.
Tips for Best Results
- Check the podcast host specification before choosing bitrate — some mandate CBR 64 kbps, others accept VBR up to 192 kbps.
- Preserve ID3 tags by editing them before conversion; Mp3tag and MusicBrainz Picard handle round-tripping cleanly.
- If the TTA is 24-bit studio audio, the VOC at 16-bit is sufficient for listening; higher is wasted on consumer playback gear.
Frequently Asked Questions
Lossy-to-lossy conversions (most combinations) re-compress the audio, which technically introduces some loss. At a 192 kbps or higher target it is inaudible on normal equipment. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy transcodes are only as good as the target bitrate you choose.
For voice content (podcasts, audiobooks, lectures) 128 kbps is indistinguishable from higher bitrates. For music, 192-256 kbps covers most listening; 320 kbps is the ceiling for VOC and the right choice for audio you plan to edit further. Above that, prefer a lossless target instead.
Yes. Title, artist, album, year and cover art travel from the TTA container to the VOC container automatically where both formats support them. If a tag field has no VOC equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
