Title (EN) SELECTIVE BANDWIDTH EXTENSION
(FR) EXTENSION SÉLECTIVE DE BANDE PASSANTE
Abstract: front page image
(EN)A method of receiving an audio signal (RX) includes measuring a periodicity of the audio signal (RX) to determine a checked periodicity. At least one best available subband is determined. At least one extended subband is composed, wherein composing includes reducing a ratio of composed harmonic components to composed noise components if the checked periodicity is lower than a threshold, and scaling a magnitude of the at least one extended subband based on a spectral envelope on the audio signal (RX).
