I have a very superficial background with electronics. I'm attempting to take an audio signal (specifically, a guitar signal; however, frequency range would be a plus) and do what is known as bitcrushing in music; essentially, reduce the fidelity of a signal to produce a level of distortion. In this case, I'm seeking to recreate the nostalgic 8 bit sound of old video game soundtracks. From what I've been able to unearth, I need a 44kb/s sample rate, with an 8-bit A/D converter, and a D/A converter. Can anybody direct me to an appropriate IC's and/or circuit I can use?

Thanks in advance! :D

Oh, this is usually done in a Digital Audio Workshop, or through file conversion on the computer, but I'd like to be able to use this in a live setting.
