The present invention provides a method and equipment for automatically adjusting speaker delay parameters, wherein the method includes: receiving a pulse-modulated audio signal from any speaker to be tested in the room; For the initial test time, the received audio signal and the test pulse signal are convoluted at the receiving position to obtain the relative delay of the loudspeaker arriving at the receiving position; Calculating the delay parameter corresponding to each speaker to be tested; performing delay adjustment on the speaker corresponding to the delay parameter according to the delay parameter. The above solution solves the problem of delay adjustment of large indoor loudspeakers, and can achieve the technical effects of saving delay adjustment labor costs and time costs, and improving delay adjustment accuracy.
Description
Technical field[0001]The present invention relates to the field of speech signal processing, and more particularly to a method and apparatus for automatic adjustment of speaker delay.Background technique[0002]In large indoor occasions such as the cinema, conference room, stage and KTV large package, after the construction of the new project, due to the large interior, there is often a distance from multiple speakers, and the distance listening position is different, causing multiple The speaker has different delays in the sound information reaching the listening position at the same time, which will not only generate phase deviations, resulting in a decrease in the intensity of sound information, and due to the superposition of different delays, the sharpness of the sound information will result in a decrease in the sharpness of the sound information. Large reduces listening effects and user experience.[0003]In general, engineers use visual estimates, distance measurements, and othe...
