Spectrum Slice
Your data as one picture — the top slice of a sculpture. Cable an Audio FFT (or any list: a Data Lab array, EEG band powers) into Data: Rings put the bass in the centre and the treble outside, Spokes and Bloom go round the circle, Spiral runs the spectrum along an arm, Bars is the classic analyser, Grid a heat-map mosaic. Range picks the part of the spectrum, Frequency Scale Log gives the bass room, Auto Level keeps any source in range. Symmetry mirrors it round the circle, Turbulence warps it with flowing noise, Threshold turns the soft heat map into solid shapes. Stack it in time with Time Slice 3D.
Inputs
| Port | Type | Default |
|---|---|---|
| EnableOff: the picture is cleared. | bool | true |
| DataThe numbers to draw: an Audio FFT's spectrum, or any list — a Data Lab array, EEG band powers, Spectral Synth's Harmonics Data. | structure | — |
| LayoutRings: bass in the centre, treble outside. Spokes: the spectrum round the circle, length = loudness. Bloom: a filled outline that swells with it. Spiral: along an arm. Bars: the classic analyser. Grid: a heat-map mosaic. | int | 0 |
| BinsHow many values are drawn (4…512): fewer = broad bands, more = fine detail. | int | 128 |
| Range LowWhere in the list the picture starts, 0…1 (a spectrum: 0 = the lowest bass). | float | 0 |
| Range HighWhere it ends, 0…1. A spectrum's top half is mostly air — 0.5 keeps the music. | float | 0.5 |
| Frequency ScaleLinear: every value the same room. Log: low values (bass) get more room, as the ear hears it. | int | 1 |
| Auto LevelOn: divided by its own recent peak, so a quiet microphone and a loud file both fill the shape. | bool | true |
| GainMultiplies the values (after Auto Level). | float | 1 |
| ContrastAbove 1: only the loud parts stay bright. Below 1: quiet parts come up. | float | 1 |
| SmoothingCalms restless data from frame to frame, 0…1. | float | 0.6 |
| SizeThe slice's radius (Bars, Grid: half its height), Grafit units. | float | 0.9 |
| RotationTurns the slice, degrees clockwise. | float | 0 |
| SymmetrySpokes, Bloom: the spectrum mirrored round the circle this many times — a mandala. | int | 1 |
| TurnsSpiral: how many times the arm winds round. | float | 3 |
| SoftnessSoft edges, 0 = crisp. | float | 0.1 |
| Threshold0: a soft heat map, brightness = value. Above 0: solid shapes wherever the value passes it — what a sculpture needs. | float | 0 |
| TurbulenceWarps the slice with flowing fractal noise (Grafit units). 0 = off, the shape is pure data. | float | 0 |
| Turbulence ScaleHow fine the turbulence is. | float | 3 |
| Turbulence SpeedHow fast the turbulence flows. | float | 0.3 |
| SeedAnother turbulence pattern. | int | 0 |
| Color ModeGradient by value: loud parts at the Gradient's end. By frequency: bass to treble along it. White: for masks. | int | 0 |
| GradientThe palette. Unplugged: ink → violet → amber → white. | structure | — |
