METHOD AND DEVICE FOR CHARACTERISING A SIGNAL AND METHOD AND DEVICE FOR PRODUCING AN INDEXED SIGNAL |
| 摘要 |
The invention relates to a method for characterising a signal representing an audio content. A measure is determined (12) for a tonality of the signal, whereupon information relating to the audio content of the signal is obtained (16) on the basis of the measure for the tonality of the signal. Said measure for the tonality of the signal, used to analyse the content, is stable in relation to a signal distortion, e.g. resulting from MP3-coding, and has a high correlation with the content of the signal examined. |
