Description: Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1] or [2] for more detail about the algorithm.

Description: 学习并找到降噪方法,对语音信号背景噪声做处理,使得声音更清晰。-The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.

Description: 谱减算法为最早的语音降噪算法之一,它的提出,基于一个简单的原理:假设语音中的噪声只有加性噪声,只要将带噪语音谱减去噪声谱,就可以得到纯净语音幅度。这么做的前提是噪声信号是平稳的或者缓慢变化的-Spectral subtraction algorithm is one of the first voice noise reduction algorithm, which has been proposed, based on a simple principle: if only the voice of the noise additive noise, just noisy speech spectrum subtracting the noise spectrum, you can get clean speech amplitude . Do so on the premise that the noise signal is stationary or slowly varying Platform: |
