STFT Frequency Filter, Vocoder & Comb Generator
Precision Frequency Domain Filtering, Spectral Vocoding & Additive Mic+Noise Layering
1. Audio Input Mode
Live Mic STFT Filter
Filter target frequencies on live mic input
Synthesized Noise Carrier
IFFT Generated Noise Filter
Spectral Vocoder
Live Mic modulates Carrier Noise
Live Mic + Noise Mix
Layer live mic audio & carrier noise together
2. Filtering Behavior
🚫 FILTER OUT / NOTCH (Silence Target Bands)
🎯 FILTER IN / BAND-PASS (Keep Target Bands)
Acoustic Feedback Warning:
Please use
headphones
when enabling live mic modes to prevent feedback loops!
