title: Python read microphone without PyAudio
body: <p>I'm trying to collect data from a Geiger counter using the microphone and process it using Python. However, I'm using a university computer so I'm not allowed to install the <code>PyAudio</code> module which seems necessary for this job (<a href="https://stackoverflow.com/questions/14642443/python-read-microphone">Python read microphone</a>). Are there any equivalent functions in <code>numpy</code>, <code>matplotlib</code> or <code>scipy</code>?</p>
