Fast, secure TTA to FLAC conversion. No registration required.
Setup: TTA is the True Audio lossless codec, fast to decode on low-power devices. Goal: an interchangeable FLAC. A TTA to FLAC conversion is typically about compatibility: some players refuse TTA, many accept FLAC. 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 FLAC comes back in seconds. One more beat. TTA is the True Audio lossless codec, fast to decode on low-power devices. Receiving format: FLAC is the Free Lossless Audio Codec, offering 40–60% compression with zero quality loss.
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.
FLAC Audio
Target formatFLAC is an open-source lossless audio codec that compresses audio to roughly 50-60% of its original size without any quality loss. It is the preferred format for audiophiles and music archival.
Why convert TTA to FLAC
Moving from TTA to FLAC 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 FLAC codec supports to avoid compounding compression.
HOW TO CONVERT
TTA → FLAC
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 FLAC with ID3 tags intact.
Save the output
Click to download the FLAC. Batch uploads are bundled into a ZIP for single-click retrieval.
Common Use Cases
Share across platforms
Send FLAC files to anyone without worrying about whether they have the right software for TTA.
Embed in documents
Drop FLAC output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
FLAC 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 FLAC — 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.
FLAC Strengths
- Lossless — decoded audio is bit-exact identical to the source.
- 40-60% smaller than uncompressed WAV/AIFF.
- Free, patent-free, open-source reference implementation.
- Built-in error detection via MD5 checksums.
- Streaming-friendly — seek tables let you jump to any timestamp instantly.
Limitations
- File sizes still large compared to lossy codecs (5-10× bigger than AAC for same audio).
- Not suitable for low-bandwidth scenarios like streaming on mobile data.
- Older MP3 players and car stereos may not decode FLAC.

TTA

- Full CD album 250-350 MB
FLAC
- 3-min song (CD quality) 20-30 MB
- Full album (10 tracks, CD) 250-400 MB
- 3-min song (hi-res 24-bit/96 kHz) 80-120 MB
- Live concert recording (24-bit) 2-10 GB
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 FLAC. 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 FLAC 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 FLAC 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 FLAC container automatically where both formats support them. If a tag field has no FLAC equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
