This application provides an echo cancellation
system, method, and device based on a complete reference
signal on the
server side, applicable to the field of audio
processing technology. The
system of this application uses the original audio sample from the
client, stored on the
server side, as a precise reference
signal. When returning the output
audio signal to the
client, the
server has already subtracted the
client's corresponding reference
signal from the globally mixed audio, thereby eliminating the client'
s voice and preventing the client user from hearing their own voice, thus achieving echo cancellation. Compared to existing technologies where echo cancellation is achieved by the client estimating the echo using AEC technology, the
system of this application leverages the server's possession of a complete reference signal to achieve echo cancellation, reducing complexity while ensuring the accuracy of echo cancellation.
