Either. Basically what I wanted to know was if I take a 8051, an EEPROM, programmed the EEPROM with the audio files, converting them to whatever I decide to first, of course, what else would I need to do to have the 8051 output the audio to a speaker, and that is what I have not been able to find. I know it can't be extremely difficult, but I am just getting into this because I just now have the ability (money) and basically I am trying to find everything I'm going to need before I order so that maybe I won't have to make a second order just to do one thing.
