Diseño y construcción de una pedalera de guitarra digital basada en Raspberry Pi

The recent advance of the embedded systems has led to the development of the devices that adjust to specific applications in any social environment, including the music industry. With the emergence of the programmable and high processing capacity devices, the music industry has taken advantage over the DSP algorithms to obtain the highest quality of audio, and at the same time, the highest manipulation over it. The current project aims the implementation of music, digital signal processing and hardware modules concepts to create a real time audio processor of an audio signal that comes from an instrument of electromagnetic vibrations basis. On the mainstream music industry, it is known as a guitar digital pedal to produce certain effects. The project focuses on a specific effect and the control of the sound quality on the output. The application develops over a Raspberry Pi hardware platform with Python programming language for the interface and the processing algorithms as well. In conclusion, the project emulates similar products of the music industry. Each year, this industry push the bounds of technology that control the sound of many artists on concerts, records, and even at home with simple devices for any kind of user.
