Building an Audio Recorder on Raspberry Pi running Alpine Linux

Do you have a podcast that you wanted to start or already have one that you wish was easier to record?  Well, this probably won't do that, but it is a great Alpine Linux project on Raspberry Pi!  We are going to create a small program to record audio from a USB audio interface attached to the Raspberry Pi, using "arecord" to actually record the audio.  We will also create a basic web interface to start and stop the recording, as well as download the recorded files.  For those of you looking for a project to tune your skills, this may be a fun one to follow along.  I am going to be doing this from the ground up, and will be developing it in real time, so you will see every step as we go.
