Patent ID: 7356476

Claim:
An audio signal processing apparatus, comprising: a signal deleting means for deleting an audio signal in an anomalous segment, a deducing means for deducing a correct audio signal by referring to a waveform of the audio signal before and after said deleted segment; a repair signal generating means for generating a repair signal for repairing the signal of said deleted segment based on said deduced result; a signal connecting means for inserting said repair signal into said deleted segment and connecting said repair signal with the audio signal before and after the deleted segment; and anomaly detecting means for detecting an anomalous state of the audio signal and performing said processing when detecting said anomalous state, said anomalous state detecting means detecting said anomalous state by detecting skip scanning of a reading means when reading an audio signal from a recording medium, wherein said recording medium comprises a randomly accessible rotary recording medium, said reading means comprises a head able to randomly access said rotary recording medium, and said anomalous state is judged by detecting a time of skip operation of said head.
