Discrete Parameter Specifications & Acoustic Function
ZERO MS REFERENCES • 100% SAMPLE CALCULATIONS
| Parameter Identifier | UI Control Target | Sample-Domain Range | DSP Mechanics & Acoustic Role |
|---|---|---|---|
| input_source | Input Tri-Matrix | Synth / Mic / Both | Switches the audio bus feed between the internal procedural noise engine, the live ADC microphone input buffer, or a summed composite signal. |
| mic_gain | Live Mic Preamp Gain | 0.00 – 2.00 (0% – 200%) | Independent linear amplification applied to the hardware audio input stream prior to AGC limiting and waveguide injection. |
| mic_agc | Mic AGC / Fast Limiter | Enabled / Disabled | Fast-attack ($1.5\text{ ms}$), program-dependent release ($80\text{ ms}$) dynamic envelope follower with a soft-knee threshold at $-3\text{ dBFS}$ to protect against feedback loops. |
| comb_delay | Comb Delay Duration | 1.0 – 65,536.0 samples | Sets the circular buffer read pointer distance in discrete samples. Fractional values are resolved per sample using linear interpolation: $(1-f) \cdot y[n-i] + f \cdot y[n-i-1]$. |
| comb_fb | Wall Reflectance (Feedback) | -0.98 to +0.98 | Feedback scalar applied to the delayed sample. Positive feedback ($+\text{fb}$) creates integer standing waves (open pipe); negative feedback ($-\text{fb}$) creates odd-order harmonics (closed pipe). |
| comb_damp | High-Frequency Damping | 0.01 – 0.98 | Single-pole lowpass recursive filter applied inside the waveguide loop: $y_d[n] = d \cdot y[n] + (1-d) \cdot y_d[n-1]$. Models high-frequency absorption. |
| comb_lfo_depth | Delay LFO Sweep Depth | 0.0 – 40.0 samples | Continuous sinusoidal modulation applied directly to the fractional sample read pointer: $D[n] = D_0 + \Delta D \cdot \sin(\theta[n])$. |
| formants_on | Formant Bank Toggle | Enabled / Disabled | Enables or disables the 6-band State-Variable Bandpass filter array. When disabled, the input feeds directly into the comb waveguide. |
