Free online TTA to CAF converter

Source format: TTA

TTA stands for True Audio, a lossless audio format designed to preserve the original sound data without quality loss. It is used by audio enthusiasts, archivists, and some niche media players where exact audio preservation matters. Typical uses include storing music collections, archiving recordings, and keeping a bit-perfect copy of a source track while still benefiting from compression.

Target format: CAF

CAF means Core Audio Format, an Apple-developed container for audio data. It is commonly used on macOS and iOS systems, especially in professional audio workflows and applications that rely on Apple’s audio frameworks. CAF supports large files, high sample rates, multiple channels, and a wide range of audio encodings, making it useful for editing, recording, and long-duration audio storage.

How to perform the conversion

The most practical way to convert TTA to CAF is to use a desktop audio tool that can decode TTA and export to CAF, or to use a command-line workflow with FFmpeg if your build supports both formats. Because CAF is a container, the exact audio codec inside it matters; in many cases you will export uncompressed PCM audio for maximum compatibility.

1. Install a converter that supports TTA input and CAF output. On macOS, professional audio tools or FFmpeg-based workflows are often the most reliable.
2. Open the .tta file in the application.
3. Choose File → Export or File → Save As, then select CAF as the output format.
4. If the program asks for codec settings, choose PCM or another compatible uncompressed option for best interoperability.
5. Start the conversion and verify the resulting .caf file in your target player or editor.

If you prefer command-line conversion and your FFmpeg build supports the formats involved, a typical workflow is to decode the TTA file and write CAF output, for example with ffmpeg -i input.tta output.caf. The exact result depends on the codecs available in your FFmpeg build and the audio stream inside the CAF container.

Notes on quality and compatibility

TTA is lossless, so converting it to CAF can preserve audio quality only if you keep the audio uncompressed or use a lossless codec inside CAF. If you convert to a lossy codec, the result will no longer be bit-perfect. Also note that CAF support is strongest in Apple software; some non-Apple players and editors may not open CAF files, or may only support certain codecs inside the container.

Another important limitation is that CAF is a container, not a single codec. Two CAF files can behave differently depending on whether they contain PCM, AAC, ALAC, or another audio stream. For maximum compatibility, especially in editing workflows, uncompressed PCM in CAF is usually the safest choice.
