Method for determining filtration to be applied to set of loudspeakers in room in listening station, involves determining filtration to be applied to set of loudspeakers based on ratio between target profile and average energy profile

摘要

The method involves determining frequency responses (E14) respectively generated by a set of loudspeakers at one point. An average energy profile is determined (E18) based on the frequency responses by determining the sum of frequency response modulus generated at the point. The average energy profile associated with the point is determined by dividing the sum by the square root of the number of modules greater than a threshold value. The filtration to be applied to the set of loudspeakers is determined (E22) based on the ratio between a target profile and the average energy profile. Independent claims are also included for the following: (1) a device for determining filtration to be applied to a set of loudspeakers (2) a computer program comprising a set of instructions for performing a filtration determining method.
