Abstract
Systems and methods for processing a signal of an electric guitar are provided. An input guitar signal is received by a portable handheld computing device. The input guitar signal is processed using the digital signal. The combined guitar output is transmitted.
Claims19
A method for processing an electric guitar signal, the method comprising:
- receiving the output of an electric guitar at an audio input of a portable handheld computing device as an input signal to the portable handheld computing device, the output of the electric guitar is received via an audio coupling device that comprises at least one electronic circuit component that electrically couples the output of the electric guitar to the portable handheld computing device, the portable handheld computing device comprising a microprocessor, operating system, memory, touchscreen visual display, wireless internet connectivity, digital music player, web browser, means for downloading software from a server of an application distributor, and means for installing downloaded software independently from other software contained in the portable handheld computing device, wherein the audio coupling device comprises a buffer amplifier circuit that receives an input signal with a high impedance and generates an output signal with a low impedance;
- processing the input signal from the guitar at a digital signal processing block to optionally add user-selectable audio effects, the digital signal processing block configured by a software application downloaded from an applications server to the portable handheld computing device, the software application installed independently from other software contained in memory on the portable handheld computing device, the processing resulting in a signal output;
- and
- outputting the signal output.

A system for processing an audio signal, the system comprising:
- a portable handheld computing device comprising a microprocessor, an operating system, memory, a touchscreen visual display, wireless internet connectivity, a digital music player, a web browser, means for downloading software from a server of an application distributor, and means for installing downloaded software independently from other software contained in the portable handheld computing device;
- an audio coupling device that couples an electric guitar and the portable handheld computing device, the audio coupling device comprising at least one electronic circuit component that electrically couples an output of the electric guitar an audio input of the portable handheld computing device, wherein the audio coupling device comprises a buffer amplifier circuit that receives an input signal with a high impedance and generates an output signal with a low impedance;
- and
- a software application downloaded from a server of an applications distributor to the portable handheld computing device, the software application containing executable instructions that when executed instruct the processor of the portable handheld computing device to execute instructions stored in memory to:
- receive the output of the electric guitar, the output of the electric guitar being coupled to the portable handheld computing device via the audio coupling device, the output of the electric guitar being received as an input signal to the portable handheld computing device;
- process the input signal from the electric guitar to optionally add user selectable audio effects to produce a signal output;
- and
- output the signal output.
