Rotating speaker array

An audio effects apparatus comprising:

• a rotatable sound directing device that is operable to direct acoustical sound waves along a rotatable sound directional axis;
• a rotary device coupled to the rotatable sound directing device, the rotary device operable to continuously rotate the rotatable sound directional axis of the rotatable sound directing device about a rotational axis in response to a rotational drive signal;
• an encoding device for generating a rotational position signal that is indicative of a rotational position of the rotary device;
• an audio input for receiving an audio input signal;
• and
• a motion control and audio signal processing device for receiving the rotational position signal and the audio input signal, for generating the rotational drive signal based at least in part on the rotational position signal, and for modulating the audio input signal based at least in part on the rotational position signal, thereby generating a modulated audio signal.
