Built this as a learning tool for audio effects using Web Audio API and Tone.js. Load any audio file (WAV/MP3/OGG) and apply 16 different effects with Off/Subtle/Overt intensity levels. All processing happens locally in the browser.
Originally designed to help non-technical users understand how audio filters work by creating dramatic voice changes (hence the tongue-in-cheek name), but it's become useful for quick audio experimentation in general.
The three-tier intensity system makes it easy to hear exactly how each effect modifies the signal, which I found helpful when learning about filters, distortion, modulation, etc.
