Complete Guide: MKV Audio Player
Everything you need to know about using this tool effectively
The MKV Audio Player extracts and plays the audio track from Matroska MKV video files directly in your browser. MKV is a common container for movies, TV shows, and downloaded video content. This tool lets you listen to the audio from an MKV file without needing a video player or downloading any software. Playback runs locally using FFmpeg via WebAssembly.
MKV (Matroska Video) is a flexible multimedia container that holds video, audio, and subtitle tracks. The audio inside an MKV can be encoded in many codecs, most commonly AAC, AC3, MP3, or DTS. Browsers cannot decode MKV containers natively. This player uses FFmpeg compiled to WebAssembly to extract and decode the audio track for in-browser playback.

Wait for FFmpeg to load
On first use, the FFmpeg WebAssembly binary loads from a CDN. This takes a few seconds. Subsequent plays are immediate.
Play and listen
FFmpeg extracts the first audio track from the MKV and begins playback. Use the controls to play, pause, seek, and adjust volume.
Only the first (default) audio track is extracted. MKV files with multiple language tracks will play the default track.
Multichannel audio (5.1 surround) is downmixed to stereo for browser playback.
Large MKV files may take a moment to decode before playback begins.
To save the audio, use the MKV to WAV or MKV to MP3 converter.
On first use, wait a few seconds for FFmpeg to load before playback starts.
Why can't browsers play MKV files natively?
The MKV container uses video codecs such as H.264 and H.265 that require licensing or are not universally supported in browsers. This player uses FFmpeg to decode the audio track regardless of the video codec inside the MKV.
Will I hear surround sound?
No. Multichannel audio is downmixed to stereo for browser playback. To preserve discrete channels, use a desktop media player with full AC3 or DTS support.
Is my file uploaded to a server?
No. FFmpeg runs in your browser via WebAssembly. Your file is processed locally and never sent to any server.
Why does playback take a moment to start?
The FFmpeg WebAssembly binary loads on first use. This takes a few seconds. Large MKV files also take a moment to decode. Subsequent files play faster.
Can I choose which audio track to play in a multi-track MKV?
No. This player extracts the first (default) audio track. To select a specific track from an MKV with multiple audio tracks, use MKVToolNix to extract the desired track first.
