| 1. A sound-processing apparatus comprising:
a synchronized-sound-generation device for generating at least one or more new synchronized sound signal that is synchronized
with a sound signal to be modulated;
a parameter-detection device for detecting a parameter that indicates an attribute of the generated synchronized sound signal;
a converted-signal-generation device for generating a converted signal based on the detected parameter;
a modulation device for modulating the sound signal based on the generated converted signal; and
a time-difference-setting device used for setting a starting time difference between the sound to be modulated and the synchronized
sound to be generated; wherein
the synchronized-sound-generation device generates the synchronized sound having at least one or more time difference based
on at least one or more time difference that is set by the time-difference-setting device, wherein
the parameter-detection device detects the beat of the synchronized sound signal, wherein the converted-signal-generation
device comprises:
a sound-level-detection device for detecting the sound level of the synchronized sound signal of the detected beat portion;
and
a detection-sensitivity-setting device for setting the detection sensitivity for the sound-level-detection device; and wherein
the modulation device changes modulation of the sound signal to be modulated based on the detected sound level.
