The time involved in measuring the linear characteristics of acoustic systems is a common problem in audio signal processing. Recent years have witnessed a major advance in multiple-channel sound reproduction systems. Using the simple idea of frequency-domain multiplexing, a technique for performing simultaneous multiple-channel impulse response measurements is proposed. A previous technique that uses time-domain multiplexing is also revisited. Several measurements are performed in order to compare the reliability of simultaneous and sequential methods. Experimental results show that both methods have similar accuracy, but the simultaneous measurement case provides measurement versatility and saves time.
