Detecting nonlinear amplitude processing

摘要

Disclosed is a computer system comprising an audio processing module, an echo cancellation module and a control module. The audio processing module is configured to process an audio signal and output the processed audio signal to e.g. a speaker (or similar) of the system. The echo cancellation module is configured to cancel echo from an audio signal received via e.g. a microphone (or similar) of the system. The control module is configured to detect a condition indicative of nonlinear amplitude processing by the audio processing module and control said echo cancellation by the echo cancellation module based on the detected condition.

1. A computer system comprising:
an audio processing module configured to process an audio signal and output the processed audio signal to an audio output device of the system; an echo cancellation module configured to cancel echo from a received audio signal received via an audio input device of the system; and a control module configured to detect a degree of nonlinear amplitude processing by the audio processing module and control said echo cancellation by applying more or less aggressive echo cancellation settings by the echo cancellation module based on the detected degree.
