I am using librosa 0.6 in anaconda and i have also installed ffmpeg but i am still getting this error
the code is
a = np.exp(spectrum) - 1
p = 2 * np.pi * np.random.random_sample(spectrum.shape) - np.pi
for i in range(50):
S = a * np.exp(1j * p)
x = librosa.istft(S)
p = np.angle(librosa.stft(x, N_FFT))
librosa.output.write_wav(outfile, x, sr)
you can use this instead
import soundfile as sf
sf.write('stereo_file1.wav', reduced_noise, 48000, 'PCM_24')
