<P>PROBLEM TO BE SOLVED: To provide a mixing apparatus capable of easily composing an effective scratch reproduction tone with an audio signal in matching with a beat of the audio signal. <P>SOLUTION: The mixing apparatus is provided with: a cross fader section for providing an instruction of composing first and second audio signals; a processing section for carrying out processing of changing a signal level of the second audio signal and providing an output; a beat detection section for detecting an incidence interval time of beats of music by the first audio signal; a parameter setting section for setting the number of beats for decreasing/increasing the signal level; a calculation section for calculating a time for decreasing/increasing the signal level of the second audio signal; and a control section that controls repetition of increasing the second level to the first level within a time calculated by the calculation section after decreasing the signal level of the second audio signal received from an input section from a predetermined first level into a predetermined second level within the time calculated by the calculation section when the cross fader section provides an instruction of composing the audio signals. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
