Patent ID: 8748724

Claim:
An effects pedal, comprising: at least one audio signal input; a controller electrically coupled to said audio signal input, said controller including a control effect signal output, at least one control cue, and at least one control effect signal correlated to said control cue; a sound effect circuit electrically coupled to said at least one audio signal input and electrically coupled to said control effect signal output, said sound effect circuit including an audio signal output; wherein said controller is operable to transform an audio signal received over said audio signal input into a frequency array, wherein said frequency array is indicative of frequency content of said audio signal over a period of time; wherein said controller is further operable to identify a plurality of persistent frequencies present within said frequency array and compare at least one later in time of said persistent frequencies to at least one earlier in time of said persistent frequencies to determine if said control cue is present in said audio signal; wherein said controller communicates said control effect signal over said control effect signal output in response to identification of said control cue; wherein communication of said control effect signal over said control effect signal output causes said sound effect circuit to manipulate at least one aspect of said audio signal, thereby generating a manipulated audio signal, and to output said manipulated audio signal to said audio signal output.
