  • Switching between binaural and monaural modes
    Patent number: 9386391
    Abstract: A device including a processor and a memory is disclosed. The memory includes programming instructions which when executed by the processor perform an operation. The operation includes detecting relative position of two earphones when connected to the device, determining if a binaural signal processing mode is appropriate based on the detected relative position and switching to the binaural signal processing mode. If it is determined that the binaural signal processing mode is not appropriate, switching to monaural processing mode.
    Type: Grant

  • Method and device for noise reduction
    Patent number: 7657038
    Abstract: In one aspect of the present invention, a method to reduce noise in a noisy speech signal is disclosed The method comprises: applying at least two versions of the noisy speech signal to a first filter, whereby that first filter outputs a speech reference signal and at least one noise reference signal, applying a filtering operation to each of the at least one noise reference signals, and subtracting from the speech reference signal each of the filtered noise reference signals, wherein the filtering operation is performed with filters having filter coefficients determined by taking into account speech leakage contributions in the at least one noise reference signal.
