The present invention pertains to the field of control and manipulation of a digital audio signal by a user manipulable touch sensitive control surface. The present invention is specifically applicable to user manipulation of digital audio signals by disc jockeys (DJs). A touch sensitive surface substantially circumferential in shape is divided into two regions: an inner or central portion and an outer or circumferential portion. The inner portion responds to linear motion imparted by the user while the outer portion responds to circumferential motion. The linear motion imparted by the user in the central portion is used manipulate a digital audio data stream in order to impart a scratch effect.

The disclosure relates to control and audio manipulation of a digital audio signal by a user manipulable rotary control. The disclosure is specifically applicable to manipulation of a digital audio signal by disc jockeys (DJs). A magnet and corresponding sensor are used to obtain rotational state information from the turning of the user manipulable rotary control. This rotational state information is used to manipulate a digital audio signal. Manipulation of the digital audio includes forward and backward motion as well as a 'scratch effect'. Rotational state information obtained from rotating magnet includes the possibility of absolute rotation position as well as relative rotational position, or rotational direction.

Rotary control device for manipulating digital audio signals

The disclosure pertains to a scratch effect controller for use by a disk jockey, wherein at least one electromagnet creates the slippage tension or friction effect between the user manipulated disc, which includes a vinyl-like surface thereby simulating a vinyl record, and the rotatable or fixed platter. The strength of the electromagnet is variable so as to create a variable slippage tension or friction effect.

The controller of the present invention includes an optical navigation system which is responsive to movement, velocity of position of a rotatable platter. The optical navigation system is responsive to rotation of the rotatable platter and is further responsive to at least one degree of freedom of tilting of the rotatable platter. The rotatable platter typically includes a textured pattern so that the optical navigation system can acquire sequential surface images of the textured pattern.

Optical navigation system for rotary control based non-contact controller

The present invention is a turntable which includes an internal analog to digital converter and a controller for a standard digital format. This allows a jack for a standard digital format to be incorporated into the turntable, so that digital signals are generated to be received by the soundcard of an external computer or similar piece of digital equipment.

A control knob for controlling an underlying signal is disclosed. The control knob includes a clear radial portion which serves as an indicator on the knob. The radial portion receives light from a multi-color LED which is housed within a clear shaft of a potentiometer which rotates in concert with the control knob and controls the level of the underlying signal. The multi-color LED emits light of a color which is dependent upon the level of the underlying signal being controlled by the control knob.
