FeedbackForge with LFO Volume Modulation

Generate feedback using sine waves or noise with LFO volume modulation (sine, square, triangle, sawtooth).

Signal Source:

LFO (Volume Modulation): Disabled

Frequency Groups: Select bands to filter the signal (works with both sine waves and noise).

Sub-Bass (20-60Hz)

Bass (80-250Hz)

Midrange (300Hz-2kHz)

Treble (3kHz-8kHz)

Ultra-High (10kHz-24kHz)

Selected frequency ranges will appear here. Current mode: Sine Waves

Gain: 0.5

Filter Q (Resonance): Narrow (High Q)

Feedback Amount: 0.3

About Modes & LFO

Sine Waves: Generate pure tones at selected frequencies. Best for testing specific frequencies and creating musical feedback.

Noise: Use white, pink, or brown noise as the source. Bandpass filters isolate the selected frequency ranges, creating feedback only in those bands. Best for testing system stability and real-world signal behavior.

LFO (Low Frequency Oscillator): Modulates the master volume in a loop (100% → 0% → 100%) using sine, square, triangle, or sawtooth waveforms. Adjust the period to control the speed of modulation.

White Noise: Equal energy across all frequencies. Creates feedback across the entire selected range.
Pink Noise: More energy in lower frequencies (-3dB/octave). Feedback favors bass and midrange.
Brown Noise: Even more bass-heavy (-6dB/octave). Feedback dominates in bass.
LFO Waveforms: Sine (smooth), Square (abrupt), Triangle (linear), Sawtooth (ramp).

Note: Feedback can be loud! Start with low gain and volume.

Frequencies are bandpass-filtered to isolate feedback to selected bands only.

For best results, use headphones or external speakers with a wide frequency response.
