Abstract
A Doppler audio dealiasing system has a zero inserter that inserts zeros between input samples of signal. The resultant signal is then processed in various ways. After the zeros are inserted and a new signal is formed, the newly formed signal is filtered with or without a modulator and otherwise processed to remove inappropriate parts to generate forward and reverse audio signals corresponding to the adjuster.
