What is TTA?

True Audio (TTA) is a free, real-time lossless audio codec that provides efficient compression without compromising audio quality.

What is CAF?

Core Audio Format (CAF) is Apple's audio container designed to overcome the file size and sample rate limitations of AIFF and WAV.

When Should You Use TTA vs CAF?

TTA vs CAF: Key Differences

• •TTA and CAF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •How transparency is handled: CAF supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: 40-50% smaller than WAV for TTA vs Flexible, supports very large files for CAF.
• •TTA is optimized for lossless audio compression, archival while CAF is designed for apple audio production, professional editing — choose based on your specific workflow needs

Advantages of TTA

• ✓TTA compresses data using lossless methods, keeping file sizes manageable for Lossless audio compression, archival.
• ✓Industry-wide support means TTA files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes TTA the gold standard for archival and master copies.
• ✓From professional software to open-source alternatives, TTA works out of the box.

Advantages of CAF

• ✓At its core, CAF relies on lossless encoding — a design choice that makes it perfect for Apple audio production, professional editing.
• ✓You won't run into compatibility issues with CAF — it's a universal standard across platforms.
• ✓File size management with CAF: larger files guaranteed to match the original exactly.
• ✓Every major application in the Apple audio production, professional editing space supports CAF natively.

Common Use Cases for TTA to CAF Conversion

• Audio books
• Sound design
• Language learning
• Professional broadcasting
• Video game audio assets
• Film soundtracks

Industry Applications

Best Practices for TTA to CAF Conversion

• →For TTA to CAF: match the sample rate and bit depth to your delivery platform — 44.1 kHz / 16-bit is the standard for music
• →Apply loudness normalization (LUFS) before conversion to ensure consistent volume across your audio library
• →CAF prioritizes quality — ensure your storage can accommodate the resulting file sizes
• →Check that metadata tags (artist, album, track number) survive the conversion
• →Convert a short segment first to verify quality at your chosen bitrate
• →Keep a lossless master copy in case you need to re-encode for a different platform

Troubleshooting TTA to CAF Conversion

• !CAF audio quality degraded vs TTA → use a higher bitrate (at least 256 kbps for music)
• !CAF file won't play on your device → check format compatibility with your player or platform
• !Metadata (artist, album, title) lost after TTA to CAF conversion → some formats like CAF may not support ID3 tags
• !Volume changed after converting TTA to CAF → normalize audio levels before conversion for consistent playback
