For a number of experiments we will need to manipulate audio signals with the Raspberry Pi. Here we give a few hints on how to get audio to work.
Audio Input
In order to record audio, we need to connect a microphone to the Pi. If you connect a USB mic, you can ensure that the Pi recognizes it by typinglsusb at the command line
