Abstract
A computing device includes a first housing and a second housing attached by a hinge. The first housing includes a first microphone and the second housing includes a second microphone. After determining that an angle between the first and second housing has changed to a current angle, the computing device may determine a distance between the first microphone and the second microphone based on the current angle. A first audio signal from the first microphone and a second audio signal from the second microphone may each be modified (e.g., using a beamforming algorithm) to create first and second modified audio signals. The first and second modified audio signals may include less noise than the first and second audio signals. The first and second modified audio signals may be sent to an output jack or to an audio application.
