<P>PROBLEM TO BE SOLVED: To simplify measurements for a time alignment. <P>SOLUTION: The delay measurement device is equipped with: a measuring audio output part to make channels from the first channel to the Nth channel to output measuring audio sequentially at a predefined interval A; a measurement part to collect the measuring audio and measure the time TK which is the time duration from an observation time of the measuring audio from the first channel until an observation time of the measuring audio from the Kth channel (here, 2≤K≤N); and a delay amount setting part to calculate a delay time of the Kth channel from the first channel on the basis of the predefined interval A and the time TK. <P>COPYRIGHT: (C)2013,JPO&INPIT |
