AUDIO TRACK STUDIO

Video Audio Track Editor

Extract individual audio tracks, add multiple audio files, reorder tracks and edit names, languages and the default track. Export a video with switchable audio tracks.

Video and preview

Audio tracks

Include the tracks you want to keep; export follows this list order. Uncheck an original track to remove it.

Choose a video to detect all audio tracks.

Use a three-letter code: eng (English), zho (Chinese), jpn (Japanese); und means unspecified.

Extraction and export

Extract one independent track at a time. M4A, MP3 and WAV convert the audio codec.

MKV supports more original audio codecs and preserves subtitles and their font attachments.

Added tracks use AAC. Original audio can keep its codec or convert to AAC. Video keeps its original codec by default.

Exporting 0 independent audio tracks

No audio tracks are included. The output will be silent.

Output follows the original video duration. Longer audio is trimmed; shorter audio ends in silence. A short audio track will not truncate the video.

The processing engine downloads on first use. Inputs are read locally and outputs use browser memory; large files and multiple encoded tracks may exceed device resources.

Independent, switchable tracks

Use separate tracks for languages, commentary or channel layouts. Each track is saved individually; players select one track at a time.

Original audio and picture

MKA extraction directly copies audio. Default exports copy the original video and audio; added audio uses AAC. Enable conversion when you need compatibility.
