Abstract
A system including at least one system microphone, a processor connected to computer readable memory and the at least one system microphone, a measurement microphone connected to the processor, at least one audio speaker, a signal generator connected to the processor and configured to produce signals from the at least one audio speaker for both the measurement microphone and the at least one system microphone to measure the response of the at least one audio speaker, and a device manager application executable from the computer readable memory and configured to perform the steps of calibrating the at least one audio speaker with the measurement microphone using the signals of the signal generator based on the response of the at least one audio speaker thereby creating at least one calibrated audio speaker and calibrating the at least one system microphone with the at least one calibrated audio speaker using the signals of the signal generator.
