Correlation of Pseudo Random Noise to Measure Time Delay as a Function of Frequency
Numerous digital delays and loudspeaker processors have granted the user a higher level of precise control over the alignment of loudspeakers. This paper investigates an efficient measurement method using correlated pseudorandom noise to accurately determine the acoustic center of a loudspeaker. It can be demonstrated that the measurement process is robust and applicable in less than ideal environments.
