Python TypeError: reduce_noise() got an unexpected keyword

Hi guys I'm trying to do audio classification using python and I installed a package and when I tried to use the functions, it said

TypeError: TypeError: reduce_noise() got an unexpected keyword argument 'audio_clip' hear the code of function.

import librosa
import numpy as np
import noisereduce as nr


def save_STFT(file, name, activity, subject):
     #read audio data
      audio_data, sample_rate = librosa.load(file)
      print(file)

     #noise reduction
      noisy_part = audio_data[0:25000]
      reduced_noise = nr.reduce_noise(audio_clip=audio_data, noise_clip=noisy_part, verbose=False)

     #trimming
      trimmed, index = librosa.effects.trim(reduced_noise, top_db=20, frame_length=512, hop_length=64)

     #extract features
      stft = np.abs(librosa.stft(trimmed, n_fft=512, hop_length=256, win_length=512))
     # save features
      np.save("STFT_features/stft_257_1/" + subject + "_" + name[:-4] + "_" + activity + ".npy", stft)

this code running in jupyternote book with Conda environment but It's not running in pycharm.
I installed conda environment in PYcharm but it does not work. Could you please help me know how to fix this error?
Solution

  • Answer to your question is in the error message.

    "TypeError: TypeError: reduce_noise() got an unexpected keyword argument 'audio_clip'

    I am guessing you are using noisereduce Python library. If you check the docs, it does not have audio_clip on parameters' list.

    Example of correct code:

    reduced_noise = nr.reduce_noise(y=audio_data, y_noise=noisy_part, sr=SAMPLING_FREQUENCY) # check the SAMPLING_FREQUENCY
