What is MKA Player?
The MKA Player plays .mka (Matroska Audio) files in your browser. MKA is an audio-only Matroska container, and most browsers cannot open it. Choose a file, wait for FFmpeg to load, and press play. The decoder detects the codec inside the container, so you do not need to know whether it holds FLAC, Opus, AAC, or Vorbis.
How does MKA Player work?
MKA is the audio-only variant of the Matroska container, the same family as MKV and WebM. The container can wrap FLAC, Opus, AAC, Vorbis, MP3, or other codecs, so playback depends on reading the container first and then decoding whichever codec is inside.
This tool uses FFmpeg compiled to WebAssembly to demux the Matroska file, decode the audio track, and convert it to 16-bit PCM at 44.1 kHz for the Web Audio player.
Key Features
- Reads the Matroska audio container with FFmpeg
- Decodes FLAC, Opus, AAC, Vorbis, and MP3 tracks inside MKA
- No need to know the codec in advance
- Output is 16-bit PCM at 44.1 kHz
- Play, pause, and seek controls
- Decoding runs in WebAssembly on your device
Common Use Cases
Open an MKA file from a music rip
Play audio-only Matroska files made by ripping tools and media managers.
Check an audio track extracted from an MKV
Listen to a track pulled out of a movie with MKVToolNix before you keep or delete it.
Verify a lossless archive
Confirm that an MKA file holding FLAC audio plays cleanly from start to finish.
Play an MKA file on a locked-down computer
Listen without installing VLC or a codec pack on a work or school machine.
How to Use This Tool
Choose an MKA file
Click the upload area or drop a .mka file onto it.
Wait for FFmpeg
The decoder loads on first use and stays loaded for the rest of the session.
Start playback
Press play to hear the audio track stored in the Matroska container.
Pause or seek
Use the player controls to pause, resume, or jump to another position in the file.
Pro Tips
- 1
If the file has several audio tracks, FFmpeg selects one automatically and plays that track.
- 2
Chapter marks and cover art in the file are ignored. Only the audio plays.
- 3
An MKA file with surround audio is downmixed to stereo for playback.
- 4
For audio inside a video file, use the MKV Audio Player instead.
- 5
If playback fails, the download may be incomplete. Compare the file size with the source.
Frequently Asked Questions
What is an MKA file?
An MKA file is a Matroska container that holds only audio. It uses the same container format as MKV video files and can carry codecs such as FLAC, Opus, AAC, or Vorbis.
How do I open an MKA file without VLC?
Choose the file in the MKA Player. FFmpeg decodes it in your browser, so no desktop player is needed.
Why won't my browser play MKA files directly?
Browsers support a small set of containers and codecs. Matroska audio is not part of the standard set, so a decoder has to read it first.
Does MKA keep lossless quality?
The container can hold lossless audio such as FLAC. This player outputs 16-bit PCM at 44.1 kHz, so very high sample rates or bit depths are reduced for playback.
What is the difference between MKA and MKV?
MKV can hold video, audio, and subtitles. MKA holds audio only, which makes the files smaller and simpler to manage.
