Inputs (14)
| Name | Type | Default | Description |
|---|---|---|---|
| base_sampler | COMBO | dpmpp_2m_sde | Stochastic base sampler whose per-step noise is colored. |
| eta | FLOAT | 1.000–100 | Stochasticity. eta=0 makes the SDE/ancestral step deterministic, which disables colored noise entirely. |
| s_noise | FLOAT | 1.000–100 | — |
| mode | COMBO | parametric | 2 options: parametric, gamma_matrix |
| alpha_start | FLOAT | 0.00-8–8 | Spectral exponent at the start (high sigma). 0=white, +red/pink, -blue/violet. |
| alpha_end | FLOAT | -1.00-8–8 | Spectral exponent at the end (low sigma). Interpolated over the trajectory. |
| interpolation | COMBO | linear | 2 options: linear, exponential |
| exp_sharpness | FLOAT | 4.00.1–16 | — |
| gamma_matrix | COMBO | none (parametric) | gamma_matrix mode only. Drop .pt matrices into models/colored_noise_gamma. |
| gamma_divider | FLOAT | 1.000.1–10 | — |
| gamma_shaping | COMBO | none | 3 options: none, sqrt, power |
| power_gamma | FLOAT | 1.000.1–8 | — |
| alpha_tilting | FLOAT | 0.00-8–8 | — |
| energy_scale | FLOAT | 1.000–4 | Scales noise std after unit-variance renorm. 1.0 = neutral; >1 injects more 'heat'. |
