Audio capture device selecting microphones based on wetness conditions
A recently granted patent (Publication Number: US12014116B2) outlines a method for generating output audio signals in an audio capture device. The method involves determining the wetness of specific microphones within the device and selecting appropriate audio signals to generate mono or stereo output signals based on the wetness conditions. The patent details the use of spectral response changes and sound patterns to detect wet microphones, as well as methods to determine if the device is submerged in liquid through image analysis or touch screen capacitance detection.
Furthermore, the patent includes claims for a non-transitory computer-readable storage medium storing instructions for generating output audio signals in the audio capture device. These instructions enable the processor to determine the wetness of microphones, select audio signals accordingly, and generate mono or stereo output signals based on the wetness conditions. The patent also covers the application of beamforming processes for generating stereo audio output signals and includes details on detecting wet microphones and liquid submersion through various methods like image analysis and touch screen capacitance detection.
