how to generate graph from electret microphone.

Hye. I'm student from Malaysia. My miniproject is sensor testing using electret microphone. i used processing 2.0.3 and graph.exe to display the sinewave. but there is no axis because it is digital output. what tools should i used and how to use the tools to get a graph with xy-axis?

Try connect to your PCs mic input. Use audacity (freeware) to record.

Audacity can export to a raw format (which can be imported to a spreadsheet) for further processing

ok. I'll try. thank you. :)
