Described herein is an audio calibration system and method that determines optimum placement and/or operating conditions of speakers for an entertainment system. The system receives an audio signal and transmits the audio signal to a speaker. A recordation of an emanated audio signal from each speaker is made. The system performs a sliding window fast Fourier transform (FFT) comparison of the recorded audio signal temporally and volumetrically with the audio signal. A time delay for each speaker is shifted so that each of the plurality of speakers is synchronized. The individual volumes are then compared for each speaker and are adjusted to collectively match. The method can align and move the convergence point of multiple audio sources. Time differences are measured with respect to a microphone as a function of position. The method uses any audio data and functions with background noise in real time.
