To run locally, you must use this command to run ipython notebook: `ipython notebook --pylab inline`

You will also need to install these python libraries (along with their C dependencies):

* numpy

* scipy

* matplotlib

* ipython

* scikits.audiolab

---

To record audio on your laptop, you can use [sox](http://sox.sourceforge.net/) (note that `rec` is a commnad installed with `sox`).  Here are 2 useful sox commands

* `rec -r 44100 -c 2 -b 16 A4.wav`

    - records at 44100 samples per sec, 2 channels, and 16 bits per sample

* `sox audio_2channels.wav audio_1channel.wav channels 1`

    - converts from 2 channels to 1 channel
