Fast, secure TTA to AIFF conversion. No registration required.
Setup: TTA is the True Audio lossless codec, fast to decode on low-power devices. Goal: an interchangeable AIFF. A TTA to AIFF conversion is typically about compatibility: some players refuse TTA, many accept AIFF. 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 AIFF comes back in seconds. Background. TTA is the True Audio lossless codec, fast to decode on low-power devices. Destination side, AIFF is Apple's uncompressed Audio Interchange File Format, the macOS equivalent of WAV.
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.
AIFF Audio
Target formatAIFF is Apple's uncompressed audio format, equivalent to WAV in the macOS ecosystem. It stores CD-quality PCM audio and is widely used in professional audio production on Apple hardware.
Why convert TTA to AIFF
Moving from TTA to AIFF 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 AIFF codec supports to avoid compounding compression.
HOW TO CONVERT
TTA → AIFF
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 AIFF with ID3 tags intact.
Save the output
Click to download the AIFF. Batch uploads are bundled into a ZIP for single-click retrieval.
Common Use Cases
Share across platforms
Send AIFF files to anyone without worrying about whether they have the right software for TTA.
Embed in documents
Drop AIFF output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
AIFF 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 AIFF — 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.
AIFF Strengths
- Lossless and uncompressed — bit-exact audio reproduction.
- Native to macOS and all Apple Pro Audio apps.
- Simple structure — trivially parsed by audio libraries.
- Supports up to 32-bit float, 192 kHz, and multi-channel audio.
- Rich metadata via named chunks (annotations, markers, MIDI).
Limitations
- Enormous file sizes — 10 MB per minute at CD quality.
- No built-in compression — use FLAC for lossless with smaller files.
- Big-endian byte order confuses tools written on little-endian hardware.

TTA vs AIFF — Typical file sizes
Approximate file sizes for common scenarios.
TTA
- 3-min song (CD) 20-25 MB
- Full CD album 250-350 MB
AIFF
- 3-min song (CD quality) 30 MB
- 3-min song (24-bit / 96 kHz) 100 MB
- Full album (CD, 10 tracks) 450 MB
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 AIFF. 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 AIFF 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 AIFF 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 AIFF container automatically where both formats support them. If a tag field has no AIFF equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
