  • Method and system for denoise and dereverberation in multimedia systems
    Patent number: 10354634
    Abstract: Method and system for use with multimedia signals that analyzes the signals into time-frequency frames over first and second time periods. Estimates of the noise and/or reverberation are derived from the frames. Gains are derived from the estimates and raised to a power to create modified gains. The modified gains are applied to the frame in the appropriate time periods. Modified multimedia signals are output after being processed by the modified gains.
