| 英文摘要: |
| Attenuating the undesired audio noise generated by impulse noise, such as shot and scream of brakes, is specially useful for real-time audio recording of TV or broadcasting live report. On the basis of impulse noise detection algorithms based on template, this paper improves the method of establishing the template by using multiple microphones to pick up noise corrupted signals and impulse noises in the environment. The universal of thresholds is found and a detection algorithm with slope as the characteristic is proposed by comparing a variety of feature extraction algorithms. The proposed algorithm gets a significant improvement in testing speed and accuracy, which means it is suitable for real-time processing of audio signals. |
