ActiveQ is a real-time evolving equalizer. It loads as a simple flat line spanning the window. Click anywhere in the window to create a ripple that spreads along the line, reflecting from the sides. Use the control and shift keys to move the anchor points on either side and send tidal waves through the line. Despite all the complex physics, what you see in the window is the actual spectral processing applied to any input signals. The audio engine updates just as quickly as the animation, so what you see is what is being done to the audio signal in real time.
