Changes the pitch of your web audio for fun and games.
HeliumKnob Extension
The user interface is carefully designed to be simple and intuitive, with a rotary knob similar to those found on real audio equipment. Pressing on the center of the knob toggles the effect on and off, and rotating the knob controls the effect.
The knob uses a decibel scale to match the non-linear sensitivity of the human ear, similar to professional audio equipment.
