Real time audio echo and background noise reduction for a mobile device

摘要

An audio enhancement system includes a display unit configured to exhibit a waveform corresponding to a microphone signal that is subject to an audio interference. The audio enhancement system also includes an interference reduction unit coupled to the microphone signal and configured to provide a reduction in the audio interference, wherein a reduced audio interference is indicated by the waveform in real time. A microphone signal enhancement method is also provided.

1. An audio enhancement system for a mobile device, comprising:
a display unit configured to exhibit a microphone signal waveform of a microphone of a mobile device having a speaker, a speaker input waveform that is applied to the speaker, and an echo cancelling waveform of an output of an acoustic echo canceller, wherein the microphone signal is subject to audio interference from acoustic echo feedback from the speaker and audio background noise associated with the mobile device; and an interference reduction unit coupled to the microphone signal and configured to provide a reduction in the audio interference, wherein a reduced audio interference is indicated by the echo cancelling waveform in real time, wherein the interference reduction unit includes the acoustic echo canceller coupled to an audio background noise suppressor to provide the reduced audio interference.
