Signal generator

Sine wave, pink/white/brown noise, and frequency sweep — one tool, three modes.

The signal source you reach for when commissioning a system. Pick a tone (sine, square, triangle, sawtooth), a noise color (white, pink, brown), or a sweep from any frequency to any other frequency over any duration. Logarithmic frequency control covers 20 Hz to 20 kHz in one slider.

Use headphones for low-frequency tones. Laptop speakers roll off below ~40 Hz and won't reproduce sub-bass accurately.
