So, I've been playing with bash scripting on Linux and attempting to level up my terminal wizardry. I've learned about piping data from /dev/video0 for web cams, and quickly creating image files from it, in a few different ways.
Next up, I'm wondering if I can do the same with audio. It seems like it must be possible, and perhaps relatively easy; but I can't find any reference (using udev) to which device file data would be piped from.
Does such a device exist? How would I find it?
