Abstract  Abstract

FIELD: physics.SUBSTANCE: signal processing method includes determining the minimum diversity between line spectral pairs (LSP) for LSP pairs of the high frequency band of a frame of the received audio signal. Based on the minimum diversity between the LSP it is determined that a portion of the high frequency band of the received audio signal includes a component corresponding to the artefact generation condition. The received audio signal is defined as including the noted component at least partially in response to the fact that the minimum diversity between the LSP satisfies the threshold value. In response to determining that a portion of the high frequency band of the received audio signal includes the component a high frequencies amplification parameter corresponding to a portion of the high frequency band of the received audio signal is adjusted. An output bit stream is generated the output bit stream being formed based on the adjusted high frequencies amplification parameter.EFFECT: increased accuracy of signal recovery in the receiver and reduced audible artefacts.37 cl 6 dwg
