SYSTEM AND METHOD FOR AUTOMATIC CREATION OF ATMOSPHERE SUITABLE FOR PUBLIC SITUATION AND TUNE IN THE ENVIRONMENT

摘要

1. A system (10) for automatically creating an atmosphere suitable for a social setting and mood in the environment (12), containing! - a sound receiving unit (14) adapted to receive sound (161, 162, 163) from the environment (12) and generate an audio signal (18) representing the received sound,! - an audio signal processing unit (20) adapted for receiving and analyzing an audio signal (18) for a public setting and mood in the environment (12), and! - an atmosphere creating unit (22) adapted for automatically generating control signals (24) for an atmosphere creating system (26) for creating an atmosphere based on the result of the audio signal analysis (28) (18). ! 2. The system according to claim 1, in which the audio signal processing unit (20) comprises an audio content analysis and classification unit (42) adapted to analyze the audio content contained in the received audio signal (18) and to classify the analyzed audio content. ! 3. The system according to claim 2, in which the block (42) of analysis and classification of audio content contains an algorithm (44) for selecting features and audio classification, adapted to classify audio content in at least one or more of the following general audio classes: popular music, classical music, speech, noise, crowd noise, silence, laughter! in which the algorithm (44) for feature extraction and audio classification, in particular, is further adapted to refine the classification by further classifying the general audio class into subclasses. ! 4. The system according to any one of claims 2 and 3, in which the block (42) of analysis and classification of audio content is further adapted to analyze audio content for information about the presence and / or verbal�
