SOUND SOURCE SUPPLY DEVICE AND SOUND SOURCE SUPPLY METHOD

摘要

The present invention provides a sound source supply apparatus capable of playing music with less degradation of sound by processing an original sound source such that music is not determined to be a noise. According to the present invention, it is possible to obtain a sound source supply apparatus (20) for providing a service for playing music via a portable terminal (105), the sound source supply apparatus having a sound source file storage device (200) for preliminarily storing a plurality of types of processed sound source files (202 and 203) produced by processing an original sound source of the music so as to reduce degradation of sound according to a plurality of types of codec characteristics and a sound source playback device (300) for determining a codec type (106) of the portable terminal (105) from a start signal indicative of a playback request when the sound source playback device receives the start signal, playing back one processed sound source file corresponding to the determined codec type selectively from the plurality of types of processed sound source files (202 and 203), and supplying the one processed sound source file to the portable terminal (105) so as to play the music via the portable terminal.
