Device and method for cancelling echo

An echo cancellation method, comprising:

• enabling an acoustic signal corresponding to an analog audio signal to be played via a loudspeaker of an electronic device;
• enabling a mixed acoustic signal received through a microphone of the electronic device to be converted into a mixed audio signal, the mixed acoustic signal comprising an echo of the acoustic signal played and an acoustic signal from a user;
• acquiring an echo reference signal, the echo reference signal being generated by converting the analog audio signal into a digital signal;
• and
• canceling an echo component from the mixed audio signal using the echo reference signal to obtain a user audio signal corresponding to the acoustic signal from the user.

A non-transitory computer readable storage medium, having computer programs stored thereon, wherein when the computer programs are executed by a processor, an echo cancellation method is executed, the echo cancellation method comprises:

• enabling an acoustic signal corresponding to an analog audio signal to be played via a loudspeaker of an electronic device;
• enabling a mixed acoustic signal received through a microphone of the electronic device to be converted into a mixed audio signal, the mixed acoustic signal comprising an echo of the acoustic signal played and an acoustic signal from a user;
• acquiring an echo reference signal, the echo reference signal being generated by converting the analog audio signal into a digital signal;
• and
• canceling an echo component from the mixed audio signal using the echo reference signal to obtain a user audio signal corresponding to the acoustic signal from the user.
