  • Patent number: 11330383
    Abstract: A method and an apparatus detect an echo delay. If an electronic device plays an audio and a counter is in an on state, an Nth recording data block received after the counter is turned on is acquired, where the Nth recording data block is a currently received recording data block, and N is greater than 1. Matching is performed between the Nth recording data block and a reference data block that is in a buffer, where the recording data block and the reference data block are data blocks with target duration. After the counter is on, the buffer buffers an audio data block played by the electronic device. If the Nth recording data block matches the reference data block in the buffer, a counting value is acquired. The counter performs counting if the recording data block does not match the reference data block. An echo delay is determined based on the target duration and the counting value.

  • Patent number: 11329622
    Abstract: An element of an automatic gain control system that automatically calibrates a Composite Gain vs Ambient Noise look-up table responsive to user zone gain inputs at various ambient noise levels. The table is a graph of adjacent (horizontally or diagonally) data points (nodes) mapping ambient noise to composite gain. Three algorithmic rules determine position changes of the nodes responsive to zone gain inputs. A curve may be fit to an arrangement of adjacent nodes. The curve, or the interpolated table value, is used with an ambient noise input to determine the current composite gain. The element may be used with many traditional ANC systems. Once calibrated over the full range of ambient noises in the user's space, the ANC system may never need further user zone gain inputs.

  • Patent number: 11308976
    Abstract: A method, an apparatus, and logic to post-process raw gains determined by input processing to generate post-processed gains, comprising using one or both of delta gain smoothing and decision-directed gain smoothing. The delta gain smoothing comprises applying a smoothing filter to the raw gain with a smoothing factor that depends on the gain delta: the absolute value of the difference between the raw gain for the current frame and the post-processed gain for a previous frame. The decision-directed gain smoothing comprises converting the raw gain to a signal-to-noise ratio, applying a smoothing filter with a smoothing factor to the signal-to-noise ratio to calculate a smoothed signal-to-noise ratio, and converting the smoothed signal-to-noise ratio to determine the second smoothed gain, with smoothing factor possibly dependent on the gain delta.
