Patent ID: 8208645

Claim:
A method for harmonizing calibration of audio between a plurality of networked conference rooms, comprising: a) calibrating a speaker output level of conference speakers within each networked conference room of the plurality of networked conference rooms by: (1) transmitting an audio reference signal to each conference speaker over a network from a calibration studio on the network; and (2) adjusting a speaker gain of each conference speaker to enable the audio reference signal emitted by each conference speaker to be within a predetermined output level; b) separately calibrating a microphone input level of conference microphones within each networked conference room of the plurality of networked conference rooms by: (1) emitting a tone signal from a single calibrated reference speaker, different from the conference speakers, within each networked conference room of the plurality of networked conference rooms into each conference microphone to generate a tone level signal from each conference microphone; (2) transmitting each tone level signal from the plurality of networked conference rooms to the calibration studio; and (3) adjusting a microphone gain of each conference microphone such that the tone level signal at the calibration studio is within a predetermined input level.
