Rapid calibration of multiple loudspeaker arrays

A method for testing multiple speakers in an array of the multiple loudspeakers, comprising:

• generating two or more sequences of uniquely coded waveforms with a waveform generator,
• outputting from the waveform generator at least one of i) each uniquely coded waveform itself, ii) parameters for each uniquely coded waveform, and iii) a combination of both, where the uniquely coded waveforms each have a known sequence of at least one of 1) different lengths, 2) different amplitude values, and a 3) combination of both, forming a unique identifier for that known sequence as inputs into the multiple loudspeakers in the array being tested, and
• generating audio signals from the multiple loudspeakers at approximately a same time to be received by one or more microphones to perform a simultaneous characterization of at least one of i) a calibration of, and ii) a performance of the multiple loudspeakers in the array, where each audio signal has its own uniquely coded waveform with the known sequence.
