Method and apparatus for generating fingerprint of an audio signal |
摘要 |
Methods and apparatus for generating a fingerprint of an audio signal are disclosed. The method comprises: detecting peaks in a representation of a temporal spectrum of frequencies of the audio signal, a peak being defined as a point in the representation which has a higher energy than its neighboring points; and generating the fingerprint of the audio signal as a function of a distribution of positions of the detected peaks along a frequency axis and a distribution of positions of the detected peaks along a time axis. The fingerprint of the disclosure is not only robust to many types of noise, but also robust against time scale modification and frequency shifting. |
