AudioFxLab: Learn How Audio Effects Really Work by Using Them

Audio processes like compression or gating are notoriously hard to understand from a textbook diagram or a two-minute tutorial video — they're dynamic, and a handful of static screenshots can only show so much. AudioFxLab is a free collection of interactive tools built to close that gap: each one lets you operate a real effect on a real signal, directly in your browser, and watch — through waveform and frequency-spectrum graphs — exactly how the sound changes as you move each parameter, until the process actually makes sense.

Compressor

Threshold, ratio, attack and release in real time

Noise Gate

Threshold, reduction, attack, hold and release in real time

Limiter

Threshold and output ceiling in real time

Overtones Generator

Additive synthesis you can hear and see

Comb Filter

Delay-based filtering across the spectrum
