Source format: ALAC
ALAC stands for Apple Lossless Audio Codec. It is a lossless audio format, which means it preserves the original audio quality without compression artifacts. ALAC is commonly used by Apple devices and software, including iTunes, Music, iPhone, iPad, and macOS, and it is often stored inside .m4a files. Typical uses include archiving music collections, keeping high-quality copies of CDs, and playing audio in the Apple ecosystem.
Target format: MKA
MKA is the Matroska Audio container format. Unlike a simple audio codec, MKA is a container that can hold one or more audio streams and related metadata. It is widely supported by media players such as VLC, Foobar2000, and MKVToolNix-based tools. MKA is useful when you want flexible metadata handling, support for multiple tracks, or compatibility with the Matroska ecosystem.
How to perform the conversion
The most reliable way to convert ALAC to MKA is to use MKVToolNix, which can wrap the audio stream into a Matroska container without re-encoding when the source is already compatible. If your ALAC file is in .m4a or another Apple container, first make sure the audio stream is readable by the tool.
- Install MKVToolNix on your computer.
- Open MKVToolNix GUI.
- Drag and drop the
.m4aor ALAC source file into the multiplexer window. - Verify that the audio track is selected.
- Set the output filename to end with
.mka. - Click Start multiplexing to create the MKA file.
If you prefer command-line tools, ffmpeg can also remux the audio into Matroska. Example:
ffmpeg -i input.m4a -c copy output.mka
This copies the audio stream directly, so it is fast and preserves quality. If the source file is not directly compatible, ffmpeg may need to decode and re-encode, but for ALAC this is usually unnecessary.
You can also convert the file on 101convert.com for free, without installing any software.
Notes on quality, compatibility, or limitations
ALAC is lossless, so a proper remux to MKA should keep the original audio quality unchanged. However, MKA is less common than M4A, so some portable players and car audio systems may not support it. If you need broad device compatibility, keeping the file in .m4a may be a better choice.
Also note that MKA is a container, not an audio codec. The resulting file may still contain ALAC audio inside it, which means the conversion is mainly a change of packaging rather than a change in audio format.
