Librosa is complianing that arr data is of type int, you need to convert it to float as below, . arr = np.array(samples).astype(np.float32) Code: import librosa import numpy as np import os from pydub import AudioSegment from pydub.playback import play sound = AudioSegment.from_file("test.wav") samples = sound.get_array_of_samples() new_sound = sound._spawn(samples) arr = np.array(samples Using mp3, mp4, m4a, mu-law, a-law or other lossy codecs during recording or transmission may reduce accuracy. If your audio is already in an encoding not supported by the API, transcode it to lossless FLAC or LINEAR16. If your application must use a lossy codec to conserve bandwidth, we recommend the AMR_WB, OGG_OPUS or SPEEX_WITH_HEADER_BYTE In order to do that, you need to split the filename by '.' and replace the last entry by the new extension you want. You can do this using the os.rename method. import os my_file = 'my_file.mif' base=os.path.splitext (my_file) [0] os.rename (my_file, base + '.wav') Share. Improve this answer. Follow.
