How it's made
- Source
- graphite sliding across paper fibres; independent band-limited noise layers model friction at 0.7-5 kHz and fine grain at 3-9 kHz, with a steep upper rolloff rather than ultrasonic fizz.
- Body
- quiet, broad 650-1250 Hz paper and pencil coupling follows contact; no ringing pitched modes.
- Envelope
- strokes last 45-650 ms, with 6-14 ms contact ramps, pressure dips at direction changes, and 10-25 ms releases. Groups of 3-9 strokes alternate with 100-380 ms word and hand pauses.
- Modulation
- random 25-150 Hz friction fluctuations imitate fibre-scale stick-slip; stroke velocity changes the upper cutoff and pressure contour together. All layers stop when the pencil lifts.
- Variation
- seeded timing, pressure, grain and spectral tilt vary each stroke. Pace sets hand speed, stroke length sets gesture size, hardness sets fine scratch, and tooth sets paper roughness.
- Presets
- small neat letters, hurried short notes, dark soft graphite, and long side-lead shading.
- Space
- dry, close and centred; no room tone, reverb, pencil taps or page-turn sounds are added.
