Sound Print

Scrolling spectrogram and audio fingerprint showing frequency history

2D CanvasEasyBest for: Podcasts, Study music, Frequency visualizations, Science content

Sound Print is a scrolling spectrogram — each frame adds a new row of frequency data to a ring buffer, and the history is displayed as a scrolling image. The result is a visual fingerprint of your audio that unfolds over time. Six modes change how the history is rendered — waterfall, mountain range, topographic contours, and more.

Tips & Best Practices

  1. 1

    Heatmap color mode makes the frequency content immediately readable — hot = loud.

  2. 2

    History Length 128 gives about 2 seconds of visible history at 60fps.

  3. 3

    Mountain mode creates a striking landscape — try with ambient music.
