Abstract

The invention discloses an AEC debugging method, device and storage medium. The method includes: debugging basic parameters of a device to be tested; manufacturing a duplex scene so that the device to be tested works in a duplex scene; passing the AEC The linear echo cancellation algorithm and the AEC nonlinear echo cancellation algorithm process the playback signal and the acquisition signal in a duplex scene; the playback signal and the acquisition signal reach the duplex standard after processing, and the AEC linear echo cancellation algorithm and the AEC non-linear echo cancellation algorithm are saved. Linear echo cancellation algorithm parameters; in the simplex manufacturing scene, simplex debugging is performed on the device under test; the simplex debugging result reaches the simplex standard, and the parameters of the AEC linear echo cancellation algorithm and AEC nonlinear echo cancellation algorithm are saved. By adopting the embodiment of the present invention, the AEC debugging efficiency of the VOIP equipment can be effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to an AEC debugging method, device and computer-readable storage medium. Background technique [0002] AEC (Echo Cancellation) is a function that all VOIP equipment or software must implement. The basic principle of echo cancellation is to use an adaptive filter to identify the parameters of the unknown echo channel. Based on the correlation between the loudspeaker signal and the generated multi-channel echo, the remote signal model is established to simulate the echo path. Through the adaptive algorithm Adjust it so that its shock response approximates the real echo path. Then subtract the estimated value from the signal received by the microphone to realize the echo cancellation function. But usually, the debugging of AEC is very time-consuming, because there are many parameters that need to be debugged, and the effects of some parameters in different scenario...
