If you plan to use python librosa to save a audio file, you may use code below:
librosa.output.write_wav('file_trim_5s.wav', y, sr)
librosa.output.write_wav() function allows us to save a numpy array to wav file. However, you may get this error: AttributeError: module ‘librosa’ has no attribute ‘output’. In this tutorial, we will introduce how to fix it.
How to fix this AttributeError?
Because librosa.output.write_wav() has been removed from librosa. In order to save a wav file, you can use soundfile.write().
Here is an example:
import numpy as np import soundfile as sf sf.write('stereo_file.wav', np.random.randn(10, 2), 44100, 'PCM_24')
How about soundfile.write()?
soundfile.write() is defined as the following:
soundfile.blocks(file, blocksize=None, overlap=0, frames=-1, start=0, stop=None, dtype='float64', always_2d=False, fill_value=None, out=None, samplerate=None, channels=None, format=None, subtype=None, endian=None, closefd=True)
