Abstract
Abstract A recorded music enhancement system (RMES) utilizing a recording media such as audio tape or compact disc with a separate track for a control waveform or digital code which controls secondary stimuli, such as pulsing lights, so that they pulse in time with the music, or are otherwise coordinated with the music in some artistic arrangement. This system has a triac to switch the power on and off to the lights or other secondary stimuli, and includes a tone or digital code detector which receives the input waveform from the extra track on the recording medium and operates the triac as a function of the input waveform, in essence causing lights or other stimuli to reproduce the rhythm variations of the music as it is played from the tape or other recording medium.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
In a recorded music apparatus having at least one track of a recording medium recorded with music, a recorded music enhancement system for driving at least one secondary stimulus from an additional track on said recording medium, said recorded music enhancement system comprising: (a) a waveform recorded on said additional track of substantially uniform frequency and having bursts whose time durations and spacing between bursts corespond with the desired rhythm variations of the music recorded on said at least one track of the recording medium, with the waveform signals recorded simultaneously with the recording of the music or subsequently to it; (b) a tone detector inputting said wave form and responding to the waveform by outputting a digital gate signal corresponding to the presence of said waveform during said time durations; (c) a switch operatively connected to said tone detector to switch between on and off modes responsive to said digital gate signal; and (d) at least one secondary stimulus controlled by said switch to cause said secondary stimulus to be driven in coordination with said waveform and thus in coordination with music on said at least one track.
Claim 2
Dependent Claim
189 words
In a recorded music apparatus having at least one track of a recording medium recorded with music, a recorded music enhancement system for driving at least one secondary stimulus from an additional track on said recording medium, said recorded music enhancement system comprising: (a) a waveform recorded on said additional track of substantially uniform frequency and having bursts whose time durations and spacing between bursts corespond with the desired rhythm variations of the music recorded on said at least one track of the recording medium, with the waveform signals recorded simultaneously with the recording of the music or subsequently to it; (b) a tone detector inputting said wave form and responding to the waveform by outputting a digital gate signal corresponding to the presence of said waveform during said time durations; (c) a switch operatively connected to said tone detector to switch between on and off modes responsive to said digital gate signal; and (d) at least one secondary stimulus controlled by said switch to cause said secondary stimulus to be driven in coordination with said waveform and thus in coordination with music on said at least one track.
Claim 3
Dependent Claim
37 words
A recorded music enhancement system as recited in claim 1 wherein said tone detector discriminates against all but a selected frequency, and defines means for tuning said frequency and establishing a band width around the tuned frequency.
Claim 4
Dependent Claim
25 words
A recorded music enhancement system as recited in claim 1 wherein said tone detector comprises a phase-locked loop integrated circuit and its external control circuit.
Claim 5
Dependent Claim
16 words
A recorded music enhancement system as recited in claim 1 wherein said switch is a triac.
Claim 6
Dependent Claim
19 words
A recorded music enhancement system as recited in claim 1 wherein said external stimulus is one or more lights.
Claim 7
Dependent Claim
20 words
A recorded music enhancement system as recited in claim 1 wherein said external stimulus is one or more tactile stimulators.
Claim 8
Dependent Claim
39 words
A recorded music enhancement system as recited in claim 1 wherein multiple frequencies are used with corresponing multiple tone detectors to operate multiple secondary stimuli or to operate one or more stimuli at one or more different power levels.
Claim 9
Dependent Claim
38 words
A system as recited in claim 1 wherein the recorded music apparatus is a three track system of which two tracks are used to record stereo music and the third track is used to record the waveform signals.
