Latest Patents
Jad Tabet holds a patent for an "Audio Automatic Gain Control System." This patent describes an automatic gain control (AGC) algorithm that is integrated into the digital signal processor instructions of an audio processing unit within a multimedia multipoint server. The AGC algorithm is designed to maintain the power level of audio signals across active channels within a fixed range. It allows for the use of non-calibrated microphones, compensates for long-distance signal attenuation, and improves audio level references for both audio switching and audio level video switching. The algorithm operates in two main steps: calibration and gain control. Calibration involves defining a noise threshold, while gain control includes calculating a dynamic speech detection level and determining if an incoming audio signal is speech-based. When the audio signal is identified as speech, the algorithm calculates a smoothed power estimation and updates the gain on each channel to ensure the power level remains within the desired range.
