Abstract:
1. 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.
