Therefore, the higher frequencies of the wideband signal (6 - 7 kHz) are pitch-scaled with a scaling factor of four and the resulting, scaled signal is inserted into the 8 - 12 kHz band. A subjective listening test has been conducted wherein it could be shown that the new proposal clearly outperforms a previous method for artificial bandwidth extension which is based on statistical estimation techniques.enArtificial bandwidth extension of wideband speech by pitch-scaling of higher frequenciesText/Conference Paper1617-5468
