Spectrogram Example

Create an example that uses efficient Bokeh streaming to show an updating waterfall spectrogram of live audio data.

Setting Up

This demo requires the SciPy package in order to run. To install SciPy using conda, execute the command:

conda install scipy

To install using pip, execute the command:

pip install scipy

Optionally, in order to use live audio data from a microphone, the pyaudio package must also be installed. To install pyaudio using conda, execute the command:

conda install pyaudio

If pyaudio is not installed, this example will use simulated audio data.

Running

To view the app directly from a Bokeh server, navigate to the parent directory examples/server/app, and execute the command:

bokeh serve --show spectrogram
