Reproducing device

Abstract

In a reproducing apparatus of the present invention, an input audio signal is divided into bands and an envelope value of each band is measured. Based on a change of the envelope value, a predetermined sound source is superimposed. Further, according to the envelope value of a reproduced audio signal, a tempo of reproduced music is detected and animation representation is changed in synchronism with the detected tempo. Further, a rhythm box is reproduced in synchronism with the detected tempo and a sound field is automatically selected corresponding to the detected tempo to perform synthesization.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200410078992.6, the application date is January 26, 1999, and the invention name is "reproducing device". technical field [0002] The present invention relates to a reproducing apparatus in which, for example, a predetermined sound source is superimposed on the basis of the level of the reproduced audio signal, and the tempo of the reproduced music is detected from the envelope of the reproduced audio signal to change the animation representation, tempo, in synchronization with the detected tempo. Rhythm boxes are reproduced in synchronization with the detected tempo, and sound fields are automatically selected and synthesized accordingly to the detected tempo. Background technique [0003] Generally, an audio system including a compact disk (hereinafter referred to as CD: registered trademark) player, mini disk (hereinafter referred to as MD: registered tradem...

AI Technical Summary

Problems solved by technology

[0007] But, first of all, the conventional audio system has the problem that since the user himself mixes the sound from the rhythm box or the drum pad with the reproduced audio signal through his operation, the rhythm may deviate, and the rhythm from the rhythm may deviate. The sound of the cassette or drum disc cannot be mixed with every genre of the music in question

[0008] Second, the conventional reproduction apparatus has the problem that an interactive representation corresponding to a genre of music is impossible since the spectrum analyzer representation can only represent the instantaneous sound level

[0009] Third, since the user himself mixes the sound from the rhythm box or the drum disc with the reproduced audio signal through his operation, if the tempo of the audio sound of the signal to be reproduced is varied, then following this This change is very difficult

In addition, since it is difficult for the user to recognize the beat of the reproduced music, it is very difficult for him to mix the sounds from the rhythm box or the drum disc corresponding to the said music beat.

[0010] Fourth, since the user has to determine the kind of the audio sound itself to be reproduced and set his own original sound range through a complicated manual operation, the optimum sound range cannot always be set corresponding to each kind of music
