Fast, secure TTA to WV conversion. No registration required.
Setup: TTA is the True Audio lossless codec, fast to decode on low-power devices. Goal: an interchangeable WV. A TTA to WV conversion is typically about compatibility: some players refuse TTA, many accept WV. The audio payload makes the round trip with minimal artefacts when bitrate is left at sensible defaults. Drop a TTA file into the uploader and the WV comes back in seconds. Keep in mind TTA is the True Audio lossless codec, fast to decode on low-power devices. And remember that WV is WavPack's hybrid lossless/lossy audio codec with a correction-file workflow.
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.
WavPack Audio
Target formatWavPack is an open-source audio codec that offers lossless, lossy, and hybrid compression modes. Its unique hybrid mode creates a lossy file plus a correction file that together reconstruct the original, enabling flexible storage strategies.
Why convert TTA to WV
Moving from TTA to WV 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 WV codec supports to avoid compounding compression.
HOW TO CONVERT
TTA → WV
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 WV with ID3 tags intact.
Save the output
Click to download the WV. Batch uploads are bundled into a ZIP for single-click retrieval.
Common Use Cases
Share across platforms
Send WV files to anyone without worrying about whether they have the right software for TTA.
Embed in documents
Drop WV output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
WV 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.

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 WV. 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 WV 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 WV 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 WV container automatically where both formats support them. If a tag field has no WV equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
