Inputs (11)
| Name | Type | Default | Description |
|---|---|---|---|
| s_churn | FLOAT | 0.500–2 | SDE noise strength. 0 disables the stochastic CNS term. |
| power_gamma | FLOAT | 0.750.1–3 | Power applied to the residual energy. Official unguided setting: 0.75. |
| gamma_divider | FLOAT | 1.730.1–50 | Divides gamma before residual energy is computed. Official unguided setting: 1.73. |
| energy_scale | FLOAT | 0.9800.5–1.5 | Applied after FFT filtering and unit-std normalization. Official unguided setting: 0.98. |
| alpha_tilt_start | FLOAT | 0.15-2–2 | Frequency tilt at the first step. Positive values favor higher frequencies. |
| alpha_tilt_end | FLOAT | -0.50-2–2 | Frequency tilt at the final step. |
| alpha_use_fnorm | BOOLEAN | true | Use normalized radial frequency for alpha tilting, matching the official published settings. |
| alpha_exp_interp | BOOLEAN | true | Use exponential interpolation between alpha_tilt_start and alpha_tilt_end. |
| alpha_exp_sharpness | FLOAT | 0.750.1–10 | Sharpness for exponential alpha interpolation. Official unguided setting: 0.75. |
| num_freq_bins | INT | 328–128 | Number of radial frequency bins. Official matrices use 32. |
| use_bundled_gamma_matrix | BOOLEAN | true | Load gamma_matrix_scaled.pt from this node folder. Disable to use the sigma-schedule fallback. |
