Audio signal processing method, audio signal processing apparatus, Hi-Fi video apparatus, digital video apparatus and 8 mm video apparatus

A HiFi video apparatus which magnetically records and reproduces a video signal and an audio signal by means of a rotary video head and a rotary audio head, the rotary heads respectively including a pair of rotary heads, A1, A2 and B1, B2 arranged in a double azimuth, comprising:

• a detecting means for detecting a track skip at the time of high speed reproduction, the detecting means determining a track skip occurrence when it detects a change in rotary heads;
• a deleting means for deleting a discontinuity or noise occurring in a HiFi audio signal caused by a track skip when a track skip is detected by deleting a segment of said HiFi audio signal;
• an audio signal generating means for generating an audio signal corresponding to said correct audio signal, a correct audio signal being deduced by referring to a waveform of the audio signal before and after said deleted segment of said HiFi audio signal;
• and
• a signal connecting means for inserting said generated audio signal for said-correct audio signal and connecting said inserted audio signal and the audio signal before and after the deleted segment;
• wherein,
• a correlation function for the audio signal before and after said deleted segment is calculated and referred to in order to evaluate the similarity of the audio signal before and after said deleted segment.
