SELECTIVE SCALING MASK COMPUTATION BASED ON PEAK DETECTION

A set of peaks in a reconstructed audio vector of a received audio signal is detected and a scaling mask ψ( ) based on the detected set of peaks is generated. A gain vector g* is generated based on at least the scaling mask and an index j representative of the gain vector. The reconstructed audio si...

Summary:A set of peaks in a reconstructed audio vector of a received audio signal is detected and a scaling mask ψ( ) based on the detected set of peaks is generated. A gain vector g* is generated based on at least the scaling mask and an index j representative of the gain vector. The reconstructed audio signal is scaled with the gain vector to produce a scaled reconstructed audio signal. A distortion is generated based on the audio signal and the scaled reconstructed audio signal. The index of the gain vector based on the generated distortion is output.
