Spectrum
Turn a song into an animated visualizer with lyrics, then record it as a video. Lyrics can be written automatically for free.
Overview
Spectrum is a public page that explains the tool and takes your song. Press Open in studio to continue in the Spectrum studio (/studio/spectrum-maker), which needs a free account. The studio plays the song and draws it as moving shapes. The song file stays in your browser; when you add a song in the studio only its format, size and length are sent to us, for usage statistics.

Styles and colours
Choose from 18 styles, including six 3D ones (globe, terrain, pillars, skyline, tunnel and orb), plus bars, circle, wave and particles. Change colours with a preset or your own, and adjust the background, glow and how strongly it reacts to the music.
Choosing the part to use
Under the player is a timeline with the song's waveform. The whole song is selected at first. Drag the orange handles, or type a start and end time, to pick just the part you want. Playing and the video download both use that selection only.
Press Download video (or Download selection as video) and the chosen part plays once while it is recorded. The file downloads by itself when it finishes.
Make it your own
Every style is just a starting point. Open Customize shape to change bar width, roundness, line thickness, how far it reaches, the inner radius and the number of columns (up to 200). You can also move, rotate or spin the whole visual. Reset brings the style's defaults back.
In Colors, add as many gradient colours as you like (up to 12) and set each one's percentage. Choose Smooth blend to fade between them, or Solid shares to give every colour its own block of the visual.
Lyrics
- Add the words: Type or paste them, one line per row, or import an .lrc or .txt file.
- Time them: Play the song and press Tap as each line starts. Imported .lrc files are already timed.
- Style them: Pick karaoke fill, one line, or a line with its neighbours, plus font, size and colour.
- Place text and set karaoke colours: Set the X and Y position (0 to 100 %) of the song title and of the lyrics, or use a preset. In karaoke mode choose the sung and upcoming colours, the upcoming opacity, and an optional glow and outline.
Auto lyrics
Press Generate lyrics and the song is listened to for you, then the lines are filled in with their times. It is free and needs you to be signed in.

Check the result. Singing is harder to hear than speech, so a few words may be wrong. Fix them in the lyrics box. The song is sent to our server only for this and deleted right after.
Recording the video
Press Download video and the selected part is drawn frame by frame, so the video is smooth even on a slow computer or with a heavy 3D style. A progress badge shows how far it is, and the file downloads by itself when it finishes. Keep the tab open while it renders. In Chrome, Edge and other browsers with a built-in video encoder it is a standard MP4 (H.264 and AAC, 30 fps) that plays in any player; other browsers save WebM or MP4 instead. Pick 1080p or 720p under Canvas in the Style tab. 1080p is sharper, and 720p is lighter if a 3D style stutters.
