SIGNAL turns your song into a reactive music video. Upload audio, lock visuals to the beat, drive them live with MIDI, and export a frame-accurate MP4 — all in the browser, no video editing required. Built for musicians and visual artists.
Reactive by default
Not a video editor. A visual instrument. Everything reacts to your audio — and you stay in control.
Beat detection built in
Drop in a song and SIGNAL finds the tempo and lays down a beat grid, so you can program visuals on the beat without being a musician.
WebGL feedback engine
Multi-pass shaders — feedback trails, bloom, kaleido, CRT, glitch — driven by a live FFT of your track. It looks alive because it is.
Play it with MIDI
Map notes and CCs to effects and perform the visuals live, or drag a .mid out of your DAW and let the sequence drive the show.
Bring your own footage
Use your own video or images as a reactive layer — pulse, displace, and recolor them in time with the music. Color or black & white.
Frame-accurate export
Render an offline MP4 with your audio muxed in — deterministic and frame-locked, so the file looks exactly like the preview.
Save and come back
Your tracks, footage, and visual programming live in your account — pick up a project right where you left off.
