Crude test of the built-in microphone on the Google Nexus One smartphone. The test was performed by using two applications to record the first 20 seconds of "Pump It" by the Black Eyed Peas as it was being played back through a stereo system. Both recordings were created from the same position at the same volume level. Both recordings were converted to MP3 using the same command line arguments.
