Matching Reverberation In Teleconferencing Environments

摘要

A system and method of matching reverberation in teleconferencing environments. When the two ends of a conversation are in environments with differing reverberations, the method filters the reverberation so that when both signals are output at the near end (e.g., the audio signal from the far end and the sidetone from the near end), the reverberations match. In this manner, the user does not perceive an annoying difference in reverberations, and the user experience is improved.

1. A method of matching acoustics in a telecommunications system, comprising:
receiving, in a near end environment, a first audio signal from a first far end environment and a second audio signal from a second far end environment; determining first acoustic parameters for the first audio signal and second acoustic parameters for the second audio signal, wherein the first acoustic parameters correspond to the first far end environment for the first audio signal, and the second acoustic parameters correspond to the second far end environment for the second audio signal; performing filtering on the first audio signal and the second audio signal in order to match the first acoustic parameters and the second acoustic parameters to reference acoustic parameters of a reference environment; and outputting in the near end environment the first audio signal having been filtered and the second audio signal having been filtered.
