Patent ID: 7242855

Claim:
An audio signal processing method comprising the steps of: deleting an audio signal in an anomalous segment; deducing a correct audio signal by referring to a waveform of the audio signal and evaluating the similarity of the signal waveform before and after the deleted segment; generating a repair signal for repairing the signal of said deleted segment based on the deduced result, wherein the repair signal is generated by the waveform with the greatest similarity; inserting said repair signal into said deleted segment; smoothly connecting said inserted repair signal and the audio signal before and after said deleted segment; measuring and successively adding a time discrepancy between a segment with the waveform connected by using said repair signal and a segment with said anomalous signal deleted therefrom; and performing the processing of said deducing step, repair signal generation step, and signal connection step again when a sum of the time discrepancy exceeds a constant time discrepancy so as to adjust the time discrepancy.
