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.Type: GrantFiled: August 29, 2022Date of Patent: December 6, 2022Inventor: Benjamin Slotznick
