APPARATUS AND METHOD FOR ESTIMATING AN OVERALL MIXING TIME BASED ON AT LEAST A FIRST PAIR OF ROOM IMPULSE RESPONSES, AS WELL AS CORRESPONDING COMPUTER PROGRAM

摘要

The present application refers to an apparatus (200) for estimating an overall mixing time based on at least a first pair of room impulse responses, the apparatus comprising a processing element (305) configured to determine differences between energy profiles of a first room impulse response of the first pair of room impulse responses anda second room impulse response of the first pair of room impulse responses at a plurality of different sample times of the first pair of room impulse responses,set a sample time of the plurality of sample times as a mixing time for the first pair of room impulse responses at which the difference between the energy profiles of the first room impulse response and the second room impulse response of the first pair of room impulse responses is equal to or below a threshold value, anddetermine the overall mixing time based on the mixing time for the first pair of room impulse responses.The present applicationfurther refers to a corresponding method for estimating an overall mixing time.
