Google Collab about musicinformationretrieval.com

@stevetjoa I'd like to help with updating the notebooks to run online on Google Colab. I have a few suggestions, whcih I tried to capture in the screen recording below:

ipython_audio.ipynb.mp4

1. Skip stanford_mir. Even when fetched from the repository with wget it throws an error on init(). The notebook seems to run just fine without it

# import stanford_mir; stanford_mir.init()

2. Add a line of code to fetch the audio file referenced in the notebook i.e.

# On Google Colab run this to fetch the audio file
!wget -P "audio" "https://github.com/stevetjoa/musicinformationretrieval.com/raw/gh-pages/audio/simple_loop.wav"

3. Replace librosa.display.waveplot with librosa.display.waveshow

librosa.display.waveshow(x, sr=sr)

I used ipython_audio.ipynb only as an example. If you like my suggestions, I can to submit a PR with similar updates applied to all other files. I just think the repo is great and I'd be happy to contribute.
