Voice boost for video — music and effects held back

An online tool for video where the speech is hard to make out: it splits the soundtrack into voices and background, lifts the speech and holds down music and effects. You hear the difference immediately — processing runs during playback rather than after a long conversion. The result can simply be watched, or saved as a separate file: the picture is copied untouched and only the audio changes.

1
Open a video

Drop the file into the player — playback starts at once, with no conversion step to wait through.

2
Pick a speech level

Off, Light, Medium or Strong. Medium is the default; voice and background have their own sliders under “Settings”.

3
Compare with the original

Hold the “Original” button (or the O key) to hear the untouched audio, release to come back.

4
Watch it or save it

Watch right here, or press “Save” — you get the same file with the sound you just dialled in.

Lift the voices above the music and keep the result

MP4, WebM, MOV, MKV ·

The file opens straight in the browser through Web Audio: playback starts at once and nothing is converted. Saving the fixed video is a separate step, on a button.

The audio track can be converted right here — the video itself is untouched. A two-hour film takes a few minutes, once.

Neural model: work out this moment

The normal mode computes the centre of the stereo image and answers instantly, but it has a limit: bass and drums sitting dead centre cannot be told from speech. The model separates for real — that costs a wait, so it works on a fragment around where you are rather than on the whole film.
