Source format
MKA is an audio-only Matroska container. It is commonly used to store music tracks, voice recordings, and soundtrack audio with modern codecs such as FLAC, Opus, AAC, or MP3. MKA files are popular among users who want flexible metadata support, chapter markers, and high-quality compressed audio in a single file.
Target format
CAFF stands for Core Audio Format File. It is an Apple-developed audio container designed for high-quality, uncompressed, or lossless audio. CAFF is mainly used in macOS and iOS workflows, especially in professional audio production, sound design, and applications that need reliable audio storage with rich metadata support. Its main advantage is that it can preserve audio quality very well, but it is less widely supported than formats such as WAV or AIFF.
How to perform the conversion
The most practical way to convert MKA to CAFF is with FFmpeg, because it can read Matroska audio files and write Core Audio Format files directly.
- Install FFmpeg on your computer.
- Open a terminal or command prompt.
- Run a command like
ffmpeg -i input.mka output.caf. - If the source audio is already lossless and you want to preserve quality, FFmpeg may be able to copy the audio stream into CAFF without re-encoding, depending on the codec. If not, it will need to transcode to a CAFF-compatible codec.
- Check the resulting file in an audio player or editor that supports CAFF, such as Audacity or Apple Logic Pro.
If you prefer a simpler workflow, you can also convert the file on 101convert.com for free without installing any software.
Notes on quality and compatibility
CAFF is not a universal playback format, so compatibility can be more limited than with WAV or MP3. For best results, use a lossless source codec in the MKA file, such as FLAC, if you want to keep audio quality unchanged. If the MKA contains Opus, AAC, or another compressed codec, converting to CAFF may require re-encoding, which can reduce quality if the target codec is not lossless.
Also note that metadata and chapters from MKA may not always transfer perfectly into CAFF, depending on the tool used. If preserving tags is important, test the output in your target application before converting a large batch of files.
