Last commit 08 Jan 2012 tag guitarusbspeaker, Reverseusbguitar, usbaudioguitarreverseeffects, Usbspeaker

Description: This is early stages of my project, the idea of this project is to be able to mix a guitar with windows sounds in reverse such as instrumental background music or trance music perhaps or maybe another fellow guitarist you may have downloaded from the internet. Microphone or guitar pin is p19 I would use a microphone for drums:) and that it for the moment, the code makes the mbed act as usb speaker that excepts a guitar or microphone input, but with a twist it all in reverse like a guitar reverse effects pedal but only you can mix anything you can get from the internet or any windows sound.
