... technique for LP of audio signals, see [12]and references therein. In WLP, the input signal undergoes a nonuniform frequency transformation before a conventional LP is performed, with the aim of enhancing ... containing a finite num- ber of dominant frequency components. In this way, the majority of audio signals is covered, except for the class of percussive sounds. The performa...
