An audio information provision system for providing a target with an audio information stream suitable to the target includes a database for storing a plurality of audio information streams; an inherent condition input section for receiving an inherent condition of the target; a variable condition input section for receiving a variable condition varying in accordance with time; a selection section for selecting at least one audio information stream from the plurality of audio information streams based on at least the inherent condition and the variable condition; and an output section for outputting the at least one audio information stream.

Audio information provision system

The characteristic value detection section detects a characteristic value concerning input musical data. The detected characteristic value is converted by a genre information determination section to genre information representing a genre of the contents of the input musical data. Based on the genre information, a parameter determination section determines an acoustic processing parameter which is used for adjusting the tone of the output from a acoustic processing section. In accordance with the acoustic processing parameter as determined, the acoustic processing section applies predetermined acoustic processing to the input musical data. The musical data having been subjected to the predetermined acoustic processing is reproduced by a reproduction section. Thus, the musical signal processing device makes it possible to obtain a tone which is adapted to the contents of the input musical data.
