Method for muting/unmuting microphone signal based on loudness level
A recently granted patent (Publication Number: US11947868B2) discloses a method for muting and unmuting a microphone signal using a processor. The method involves receiving an input microphone signal in a frequency domain, measuring its loudness level at a sampling rate, calculating a mute threshold level, and checking if the loudness level exceeds this threshold to determine whether to mute or attenuate the signal. The patent also includes provisions for resetting a mute delay timer, configuring the timer based on user preferences, and displaying a visual indicator of the mute status. Additionally, the method involves attenuating the input microphone signal to a level imperceptible to humans but detectable by communication applications, ensuring effective muting while maintaining signal presence.
Furthermore, the patent extends to a software product stored on a non-transitory storage medium with instructions for muting and unmuting an input microphone signal. The software product mirrors the method outlined in the patent, including determining the loudness level every 32 milliseconds, calculating the mute threshold level based on a voice activity detection mode, and configuring the mute delay timer. Users can set their preferred mute delay timer value, and a visual indicator is provided to indicate the current mute status. The software product also includes instructions for attenuating the input microphone signal to a level suitable for communication applications while remaining imperceptible to human ears, ensuring efficient muting functionality in various audio settings.
