VCVS filter

A VCVS filter is a type of electronic filter that helps to adjust the sound coming from a stereo speaker. It does this by letting some sound through and blocking out other sound. All sound travels in waves, so the filter works by adjusting how the waves travel. The filter will only allow certain amounts of sound to pass through, so that it can create different types of sound for you. It's like putting a screen door on the speaker to let in only some of the sound waves.
