System and method for controlling a digital audio source

Abstract

An apparatus for signal processing, wherein a disc is placed on a turntable and is provided with a groove which can be followed by the pick-up element, and employing a time-code signal wherein during use of the disc the said time-code signal controls the digital audio source.

What is claimed is: 
     
         1 . An apparatus for controlling an audio source, comprising:
 a player;   a disc comprising an absolute time-code signal in the audible range, wherein the disc rotates on the player;   a pick-up element deriving the absolute time-code signal from the disc;   a time-code corrector correcting the derived time-code signal; and   a time-code receiver receiving the corrected time-code signal to be used to control an audio source.   
     
     
         2 . The apparatus according to  claim 1 , wherein the absolute time-code signal comprises a right channel and a left channel. 
     
     
         3 . A method for controlling an audio source, comprising:
 processing a disc rotationally on a player, wherein the disc comprises a control signal in the audible range between 20 and 20,000 Hz;   deriving the control signal from the disc with a pick-up element;   subjecting the derived control signal to time-code correction; and   reading the corrected control signal into a receiver to provide control of an audio source.   
     
     
         4 . The method according to  claim 3 , wherein the control signal comprises a time-code signal. 
     
     
         5 . The method according to  claim 3 , wherein control of the audio source includes controlling the speed and the direction of play of the audio source. 
     
     
         6 . The method according to  claim 3 , including producing a scratch sound effect based on the speed and the direction of play of the disc. 
     
     
         7 . The method according to  claim 3 , wherein the audio source plays music while under the control of the corrected control signal. 
     
     
         8 . The method according to  claim 3 , wherein digitally recorded fragments can be located for play on the audio source with the corrected control signal. 
     
     
         9 . The method according to  claim 3 , wherein the audio source comprises one or more of a CD player, a DVD player, and an MP3 device.
