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.
