摘要： PROBLEM TO BE SOLVED: To control the reproduced sound volume so that the volume becomes a sound volume suitable for the surrounding ambient noise, and to prevent sound leakage. SOLUTION: When a user instructs automatic control for the reproduced sound volume to a reproduction apparatus 1, the reproduction apparatus 1 performs frequency analysis on the noise data of ambient noise collected by a microphone 3, and calculates an envelope information NPe and a power information NPp as feature amount. Then, the reproduction apparatus 1 classifies the ambient noise based on the calculated feature amount. In addition, the reproduction apparatus performs frequency analysis for musical piece data regarding a musical piece under reproduction, and calculates an envelope information MPe' and a power information MPp' as a feature amount. Then, the reproduction apparatus 1 classifies the musical piece based on the calculated feature amount. Moreover, the reproduction apparatus refers to a sound leakage recognition information database 43 and generates a sound leakage recognition information, based on the classified result of the ambient noise and the musical piece. Then, the reproduction apparatus sets the sound volume of the musical piece reproduced, to a sound volume by which sound leak is not recognized, based on the sound leakage recognition information.

摘要： PROBLEM TO BE SOLVED: To securely improve sound quality of audio. SOLUTION: A classification section 181 classifies a musical piece based on an audio data of a supplied musical piece. A switching control section 182 controls a switching section 183 for switching an output point of the audio data, according to a classification result of the musical piece. The switching section 183 supplies the supplied audio data to any of a frequency band spread section 188, a time band spread section 189, or time/frequency band spread section 190. A frequency band spread section 188 performs band spreading of the musical piece in a frequency domain, and a time band spread section 189 performs band spreading of the musical piece in a time domain. The time/frequency band spread section 190 performs band spreading of the musical piece in both domains of the frequency domain and the time domain. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To automatically select a musical piece which is easy to listen to, even in noisy environment. SOLUTION: A frequency analysis section 31 applies frequency analysis to noise data T of environmental noise collected by a microphone, to obtain frequency information S. An envelope analysis section 32 and a power analysis section 33 analyzes an envelope and power based on the frequency information S, to calculate envelope information Pe and power information Pp, respectively. On the basis of the envelope information Pe and the power information Pp, a noise determination section 34 classifies the environmental noise by referring to a noise parameter database 35 to create noise information indicative of the classification result. A category selecting section 36 selects a category of the musical piece according to classification of the environmental noise, based on the noise information. For example, when the environmental noise is classified into "vehicle", a category "rock" is selected. When the environmental noise is classified into "tea room", a category "classic" is selected.

摘要： PROBLEM TO BE SOLVED: To prevent sound leakage by adjusting a sound volume so that a playback sound volume may be suitable for surrounding environmental noise. SOLUTION: When a user indicates automatic adjustment of the playback sound volume to a playback device 1, the playback device 1 performs frequency analysis on a predetermined frequency band in noise data of environmental noise which is collected by a microphone 3, and calculates power information NPp as a feature amount. The playback device 1 performs frequency analysis on the predetermined frequency band in a musical piece data of a musical piece, in which playback is indicated from the music pieces recorded in the playback device 1, beforehand, and calculates power information NPp' as the feature amount. Then, the playback sound volume is determined, by comparing the feature amount NPp of the environmental noise, with the feature amount MPp' of the musical piece, and the playback sound volume of the musical piece is adjusted to the sound volume to a degree that the sound leakage is not recognized.
