There must be a nicer way than this (using the csound python libs would be my best guess), but for quick and dirty I present to you:

	arecord | aplay

From a terminal window. It just pipes the default audio input device (mic or line in) over to the default output device (built in speakers or line out). It's as crunchy as a cellophane folding competition, but there's plenty of options to investigate that likely can improve quality (arecord --help or aplay --help).
