WitrynaDefault: nextpow2(sqrt(length(x))) (the square root of the length of x rounded up to the next power of two). The window length must be larger than 3. overlap: segment overlap, specified as a numeric value expressed as a multiple of window or segment length. 0 <= overlap < 1. Default: 0.5. nfft Witryna10 paź 2024 · I do no think your c calculation is wrong. The easiest way to check that is to save the Matlab data and import it to Python. In Matlab: save ('data.mat', 'im') Then import that to Python using scipy: im_matlab = scipy.io.loadmat ('data.mat') ['im'] np.all (np.isclose (im_matlab, im)) If the last line gives you True, then that means the ...
Witryna在人工智能中，算法固然很重要，但语音的预处理却直接地决定了算法的性能上限，因此有必要对语音进行去噪处理。通过截取音频中的已知噪音部分，根据该噪音样本对整个音频进行降噪。截取噪音使用ffmpeg，降噪使用sox。
