I am getting the following error while executing the mentioned code. This is the first time I am using StackOverflow so pardon my mistakes.

  • How did you install librosa? I suggest using (mini)conda, i.e. a virtual environment. See https://stackoverflow.com/a/56252379/942774 – Hendrik Jul 05 '19 at 06:30
  • I installed librosa using "pip install librosa". After that, I imported librosa in a jupyter notebook (through anaconda) using "import librosa". Mentioned error occurred when ran the cell after giving the path to a music track that I want to analyze. – Abhishek Duhan Jul 14 '19 at 04:33
  • I recommend installing librosa using conda through the conda-forge channel to get all dependencies correctly. – Hendrik Jul 14 '19 at 06:25

On Ubuntu,you can solve the problem by installing libav-toools or ffmpeg:

sudo apt-get install libav-tools

Or

sudo apt-get install -y ffmpeg

See here.

I'm facing the same error too. For importing the audio files, you can use:

import scipy.io as sio

samplerate, data = sio.wavfile.read(location_of_file)
