  • Patent number: 11710492
    Abstract: Methods, systems, and devices for encoding are described. A device, which may be otherwise known as user equipment (UE), may support standards-compatible audio encoding (e.g., speech encoding) using a pre-encoded database. The device may receive a digital representation of an audio signal and identify, based on receiving the digital representation of the audio signal, a database that is pre-encoded according to a coding standard and that includes a quantity of digital representations of other audio signals. The device may encode the digital representation of the audio signal using a machine learning scheme and information from the database pre-encoded according to the coding standard. The device may generate a bitstream of the digital representation that is compatible with the coding standard based on encoding the digital representation of the audio signal, and output a representation of the bitstream.

  • Patent number: 11516144
    Abstract: Incremental data processing at a computerized device includes determining a number of data sets from a plurality of data sets, each comprising values in at least two dimensions. The device accesses priority lists for a subset of the data sets. The priority lists specify data values for an ordered number of dimension value sets. Each priority list is sequentially processed to determine the specified data values for combinations of dimension values that apply to device requirements. Processing is aborted when a data value is determined for each combination of the dimension values that apply to the device requirements. A data value is selected among the determined data values. A number of data sets is determined based on the selected data values. A network route from a source device to a target device can be determined in this manner.

  • Patent number: 10297263
    Abstract: A method includes extracting a voicing classification parameter of an audio signal and determining a filter coefficient of a low pass filter based on the voicing classification parameter. The method also includes filtering a low-band portion of the audio signal to generate a low-band audio signal and controlling an amplitude of a temporal envelope of the low-band audio signal based on the filter coefficient. The method also includes modulating a white noise signal based on the amplitude of the temporal envelope to generate a modulated white noise signal and scaling the modulated white noise signal based on a noise gain to generate a scaled modulated white noise signal. The method also includes mixing a scaled version of the low-band audio signal with the scaled modulated white noise signal to generate a high-band excitation signal that is used to generate a decoded version of the audio signal.
