A computer receives a microphone input signal from the participant computer that includes the test audio pattern outputted by the speaker of the participant computer, and any ambient noise picked up by the speaker of the participant computer. Ambient noise suppression is performed to cancel out any ambient noise in the microphone input signal picked up by the speaker of the participant computer. The test audio pattern sent to the speaker of the participant computer is compared with the noise-suppressed microphone input signal which includes the test audio pattern outputted by the speaker of the participant computer. An audio signal transform is generated from the comparison. The generated audio signal transform is subsequently used for performing acoustic echo cancellation of streaming audio received from the microphone input signal when the participant computer receives streaming audio and the participants engage in remote audio communications with each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for using a test audio pattern to generate an audio signal transform for use in performing acoustic echo cancellation","description":"A test audio pattern is sent to the speaker of the participant computer for outputting by the speaker.
