Mode2: Search for zero-cross points in the same way as
Mode1, but connect zero-cross points only when low-
level samples are detected around the zero-cross
points.
Mode3: At a regular interval corresponding to the
playback speed, connect the audio data before and
after the processing target with a cross fade.
OFF: Output audio data by performing rate conversion
processing. This changes the frequency
characteristics and pitch according to the specified
program play speed.
Note
Cross fade processing may be performed if zero-cross
points cannot be detected in Mode1 or Mode2 processing.
