  • Publication number: 20170287499
    Abstract: A recording is usually a mixture of signals from several sound sources. The directions of the dominant sources in the recording may be known or determined using a source localization algorithm. To isolate or focus on a target source, multiple beamformers may be used. In one embodiment, each beamformer points to a direction of a dominant source and the outputs from the beamformers are processed to focus on the target source. Depending on whether the beamformer pointing to the target source has an output that is larger than the outputs of other beamformers, a reference signal or a scaled output of the beamformer pointing to the target source can be used to determine the signal corresponding to the target source. The scaling factor may depend on a ratio of the output of the beamformer pointing to the target source and the maximum value of the outputs of the other beamformers.

  • Patent number: 9218817
    Abstract: An encoder and a method for encoding a digital signal are provided. The method includes encoding a preceding frame of samples of the digital signal according to a predictive encoding process, and encoding a current frame of samples of the digital signal according to a transform encoding process. The method is implemented such that a first portion of the current frame is also encoded by predictive encoding that is limited relative to the predictive encoding of the preceding frame by reusing at least one parameter of the predictive encoding of the preceding frame and only encoding the parameters of said first portion of the current frame that are not reused. A decoder and a decoding method are also provided, which correspond to the described encoding method.

  • Patent number: 8965775
    Abstract: A method of binary allocation in an enhancement coding/decoding for improving a hierarchical coding/decoding of digital audio signals, including a core coding/decoding in a first frequency band and a band extension coding/decoding in a second frequency band. For a predetermined number of bits to be allocated for the enhancement coding/decoding, a first number of bits is allocated to a coding/decoding for correcting the core coding/decoding in the first frequency band and according to a first mode of coding/decoding and a second number of bits is allocated to an enhancement coding/decoding for improving the extension coding/decoding in the second frequency band and according to a second mode of coding/decoding. Also provided are an allocation module implementing the method and a coder and decoder including this module.

  • Patent number: 8812327
    Abstract: A method of hierarchical coding of a digital audio frequency input signal into several frequency sub-bands, including a core coding of the input signal according to a first throughput and at least one enhancement coding of higher throughput, of a residual signal. The core coding uses a binary allocation according to an energy criterion. The method includes for the enhancement coding: calculating a frequency-based masking threshold for at least part of the frequency bands processed by the enhancement coding; determining a perceptual importance per frequency sub-band as a function of the masking threshold and as a function of the number of bits allocated for the core coding; binary allocation of bits in the frequency sub-bands processed by the enhancement coding, as a function of the perceptual importance determined; and coding the residual signal according to the bit allocation. Also provided are a decoding method, a coder and a decoder.
