TTA vs VOC
A detailed comparison of True Audio Lossless and Creative Voice — file size, quality, compatibility, and which format to choose for your workflow.
True Audio Lossless
Audio FilesTTA (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.
About TTA filesCreative Voice
Audio FilesVOC (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.
About VOC filesStrengths Comparison
TTA Strengths
- Lossless bit-exact reproduction.
- Fast, low-memory decoding.
- Open-source reference.
- Cue-sheet support.
VOC Strengths
- Retro-gaming archive format.
- Supported by DOSBox and SoX.
- Block-based structure allows streaming.
Limitations
TTA Limitations
- Compression ratio worse than FLAC.
- Niche tooling.
- Hardware support died with 2000s DAP era.
- Eclipsed by FLAC.
VOC Limitations
- Legacy — no new content since mid-1990s.
- Limited sample rates (up to 44.1 kHz).
- No metadata.

Frequently Asked Questions
TTA (True Audio Lossless) is an audio file format used to store sound recordings — music, voice, podcasts, sound effects. The format defines how the audio samples are compressed (or stored raw), what bitrates are supported, and how metadata such as title, artist, album, and cover art is embedded. It is part of the audio files family.
VOC (Creative Voice) is an audio file format used to store sound recordings — music, voice, podcasts, sound effects. The format defines how the audio samples are compressed (or stored raw), what bitrates are supported, and how metadata such as title, artist, album, and cover art is embedded. It is part of the audio files family.
VLC, foobar2000, and the default media players on Windows and macOS handle TTA natively. On mobile, iOS Music and Android media apps vary in their support — popular formats work everywhere; niche ones may need a dedicated app. If playback fails on a device, converting to MP3 or AAC usually solves it.

Upload the TTA to KaijuConverter and pick MP3, WAV, FLAC, AAC, OGG, or any other target. Our FFmpeg pipeline decodes the audio and re-encodes to the target format at sensible default bitrates (VBR ~190 kbps for music, 96 kbps for speech). Metadata and cover art travel with the audio where both formats support them.
TTA can be lossy or lossless depending on the specific variant. Lossy variants (smaller files) discard some audio detail during compression in ways tuned to be inaudible; lossless variants preserve every sample exactly but produce larger files. For distribution, lossy at high bitrate is standard; for archival, lossless wins.
