Including music and sounds¶
Music and sounds on a computer are stored as data files, usually with the file types .wav or .mp3. You can upload such a file onto your Jupyter hub account, and then access it with HTML code or a call to Python tools.
We give four examples to show the basics of how this works.
Example 1 - A local .wav file using html¶
We have uploaded a short music file onto this repo, called KolnShort.wav (a clip from Keith Jarret’s Koln concert).
A few lines of html code will create a tool on the screen, click to play.
%%html
<audio controls>
<source src="KolnShort.wav" type="audio/wav">
Your browser does not support the audio element.
</audio>
Example 2 - A remote .wav file using html¶
You can also access a .wav stored online, and play it. Here we grab a short clip from an online resource at Stanford.
A few lines of html code will create a tool on the screen, click to play.
%%html
<audio controls>
<source src="https://ccrma.stanford.edu/workshops/mir2014/audio/T37-vibraphone-8k.wav" type="audio/wav">
Your browser does not support the audio element.
</audio>
Example 3 - Python code to play a .wav sound¶
We can import a tool and play the sound within Python code, avoiding the HTML magic above. It works about the same.
from IPython.display import Audio ## only import once per notebook
Audio(data='KolnShort.wav')
Example 4 - Python code to play a remote .wav sound¶
We can also use Python code to play a clip of sound from an online resource. It works about the same as the last example.
Audio(data='https://ccrma.stanford.edu/workshops/mir2014/audio/T37-vibraphone-8k.wav')
