  • Efficient audio signal processing in the sub-band regime
    Patent number: 9203972
    Abstract: A signal processing system enhances an audio signal. The audio signal is divided into audio sub-band signals. Some audio sub-band signals are excised. Other audio sub-band signals are processed to obtain enhanced audio sub-band signals. At least a portion of the excised audio sub-band signals are reconstructed. The reconstructed audio sub-band signals are synthesized with the enhanced audio sub-band signals to form an enhanced audio signal.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: December 1, 2015
    Assignee: Nuance Communications, Inc.
    Inventors: Gerhard Uwe Schmidt, Hans-Jörg Köpf, Günther Wirsching
