HARK Development

This chapter shall include procedures and tips on HARK development. There are several disjoint steps required to get HARK to run, so this chapter should be read thoroughly to preemptively address any problems.

Microphone Name

Some nodes require a microphone name as a parameter (e.g. AudioStreamFromMic). These are the steps to determining the microphone name.

1. Open a terminal
2. To list all the recording devices plugged into the computer, run $ arecord -L
3. As suggested by the HARK documentation, the device name probably begins with "plughw". Copy and paste the text on that line. For example plughw:CARD=CameraB409241,DEV=0
4. There may be a few lines beginning with plughw and it is a bit of a trial and error process to find the right microphone.
