About Spectrogram Waterfall

Spectrogram Waterfall renders a scrolling spectrogram display where frequency is mapped to the vertical axis, time scrolls horizontally, and color intensity represents amplitude. This classic audio analysis view transforms your music into a rich tapestry of color that reveals harmonic structures, rhythmic patterns, and timbral textures invisible to the naked ear. Unlike simple bar visualizers, the spectrogram preserves temporal history -- you can see where the music has been and anticipate where it might go. Harmonic series appear as evenly spaced horizontal lines. Drum hits create vertical streaks. Sweeping synths draw diagonal lines. Vocal formants appear as shifting horizontal bands. The spectrogram turns music into a visual language that trained listeners can actually read. Spectrogram Waterfall bridges the gap between artistic visualization and analytical tool. Music producers use it to verify their mix decisions. Educators use it to teach acoustics. Content creators use it for its uniquely informative aesthetic. The color mapping is configurable, from scientific heatmaps to artistic gradients.

How it works

A high-resolution FFT (4096 or 8192 points) is computed during offline analysis for each time frame. The resulting magnitude spectrum is mapped to a column of pixels using a configurable color gradient (linear or logarithmic mapping). Columns are written sequentially to a scrolling texture buffer using a circular write pointer. The texture is rendered as a full-screen quad with the scroll offset handled in the UV calculation. Frequency axis can be switched between linear and logarithmic (mel-scale) mapping. An optional 3D mode extrudes the spectrogram into a waterfall mesh with height proportional to amplitude.

Frequently Asked Questions

What is the frequency resolution?+
With the default 4096-point FFT at 44.1kHz, the frequency resolution is approximately 10.7Hz per bin. You can increase to 8192 points for finer resolution at the cost of reduced temporal precision.
Can I use a logarithmic frequency scale?+
Yes. Mel-scale and logarithmic frequency mapping options compress the high frequencies and expand the lows, matching human pitch perception and giving more visual space to musically important ranges.
Is there a 3D waterfall mode?+
Yes. The 3D waterfall mode extrudes the spectrogram into a perspective mesh where amplitude is represented as height, creating a mountain-range-like display that scrolls toward the camera.
