Noise reduction in python using spectral gating (speech, bioacoustics, audio, time-domain signals) - timsainb/noisereduce
Installation pip install noisereduce noisereduce optionally uses Tensorflow as a backend to speed up FFT and gaussian convolution. It is not listed in the requirements.txt so because (1) it is optional and (2) tensorflow-gpu and tensorflow (cpu) are both compatible with this package. The pack...
