Source format: AC3
AC3 (Audio Codec 3, also known as Dolby Digital) is a compressed audio format commonly used in DVDs, Blu-ray discs, broadcast TV, and home theater systems. It supports multichannel audio, including 5.1 surround sound, and is valued for efficient compression and broad playback support in consumer electronics. AC3 files are often used when the goal is to preserve surround audio in a compact form.
Target format: CAFF
CAFF (Core Audio Format) is an audio container developed by Apple for macOS and iOS workflows. It can store uncompressed or compressed audio and is designed for high-quality audio handling in Apple software and professional audio environments. CAFF is useful when you need a flexible, modern audio container that works well with Apple tools and can preserve metadata and high-fidelity audio content.
How to perform the conversion
The most reliable way to convert AC3 to CAFF is with FFmpeg, which can read AC3 and write CAFF while preserving the audio stream or re-encoding it as needed.
- Install FFmpeg on your computer.
- Open a terminal or command prompt.
- Run a command such as
ffmpeg -i input.ac3 output.caf. - If you want to control the audio codec inside the CAFF container, specify it explicitly, for example
ffmpeg -i input.ac3 -c:a pcm_s16le output.caffor uncompressed PCM audio. - Check the resulting file in a compatible player or editor, such as Audacity, Logic Pro, or QuickTime Player on macOS.
If you prefer a web-based workflow, you can convert the file on 101convert.com for free, without installing any software.
Notes on quality and compatibility
AC3 is a compressed source format, so converting it to CAFF does not restore lost audio detail. If you choose an uncompressed codec inside CAFF, the file may become much larger, but it can be easier to edit and more compatible with professional audio tools. Compatibility is also important: CAFF is best supported in Apple software, while support in Windows and Linux applications is more limited. For maximum portability, consider whether you actually need CAFF or whether another container such as WAV or AIFF would better suit your workflow.
