A nonperiodic waveform is forced to a periodic character to facilitate looping of the waveform without introducing audible, and thus objectionable, sound artifacts. Nonperiodic waveforms are typically nonperiodic due to the presence of nonharmonic high frequency spectral components. In time, the high frequency components decay faster than low frequency components and looping of the waveform is facilitated. A loop forcing process and loop forcing filter facilitate looping of a nonperiodic waveform by accelerating the removal of the nonperiodic high frequency components. A loop forcing filter accelerates the removal of nonperiodic high frequency components using a comb filter having a frequency selectivity that varies in time.
