Mitigating the impact of nonlinear echos by dynamic range compression
Abstract:
Mitigation of nonlinear echoes by dynamic range compression may be provided. An audio output may be evaluated to determine whether nonlinear echoes are interfering with an audio signal. In order to reduce such nonlinear echoes, a dynamic range compression algorithm may be applied to the audio signal prior to output. The signal may be modified according to a compression wave and/or subjected to an attenuation factor.
