Visual Sound Design (VSD) is a tool for exploring basic sound synthesis, oscillators, and filtering. It enables users to create and manipulate sound oscillators (sine, pulse, square, saw, and triangle waves) and adjust their properties, including frequency, volume, panning, LFO (low-frequency oscillator) frequency, and LFO amplitude. Each oscillator is embedded within a “note” that has a dynamic envelope, allowing real-time control over attack and decay settings.

In addition to sound generation, VSD offers a range of sound filtering options (band-pass, low-pass, high-pass, and notch filtering), time-based effects (single echo, double echo, repeating echo, flanging, chorusing, and simulated reverb), and distortion effects. The UI is built using ControlP5, and the entire environment operates in real-time.
