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 (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
