// The mics *and* line-in are BOTH connected to LIN2/RIN2 on the AudioKit

// Line-in works OK on the AudioKit, generally speaking, as the mics really need
// amplification to be noticable in a quiet room. If you're in a very loud room,
// the mics on the AudioKit WILL pick up sound even in line-in mode.
