Abstract: A singing voice extraction section 2 that extracts human singing voices from the digital sound generator data 11 and obtains the signing voice data 12 in the ADPCM format, the BGM generating section 13 that generates the BGM data 13 in the MIDI format, the MIDI adjustment section 4 that generates simulated singing voice data in the MIDI format based on the extracted signing voices and adds such data to the BGM data 13, and the file generating section 5 that processes the singing voice data 12 and the BGM and simulated singing voice data 14 into a single music file 15 are established. Bandwidth limiting is significantly executed for the singing voice portion. Through generating the BGM portion in the MIDI format, the entire amount of data is decreased, and the singing voice portion that has been deteriorated in quality due to the performance of bandwidth limiting is supplemented by MIDI data. Due to this, the quality of the reproduced singing voices can be also maintained beyond a predominating level.

Abstract: A paper palette for art used for mixing colors and other paints for art or arranging the point of a brush is formed by partially bundling plural pieces of paper. Each of the pieces of paper is colored in two or more tones, which enables one to match the colors delicately and accurately in relation to a color of surroundings or a color applied to a substrate. With this paper palette, one does not have to wash it after use.
