  // and two Tympan earpieces (each with a front and back PDM micrphone)
  // connected through the earpiece audio ports (which uses the USB-B Mini connector).
  //
  -// Mixing:
  -// The front and back mic for each earpiece will be mixed into a single channel.
  -// The output will be routed to both the Tympan AIC (i2s_out[0,1]) and the
  -// Shield AIC (i2s_out[2,3]), which can be heard using the earpiece receivers
  -// or a headphone plugged into the 3.5mm audio jacks on either the Tympan or Shield
  +// Sketch Features:

  +// * After mixing the microphones, performs treble boost and WDRC compression on left and on right
  +// * Allows you to record all four mics to a 4-channel WAV file on the SD Card
  +// * Control the system via the Tympan App
