Notes

• Naming:

  • Facing audience, left mic is Mic 1/A, right mic is Mic 2/B
  • Right side is -900 to 0
  • Left side is 0 to 900

• Best measured mic distances:

  • 1m has worked for other people (16kHz-->2deg)
  • 75mm ideal for human speech
  • 250mm works as well
  • Best case is to have three mics, offering 3 different distance ranges

• Best measured ESP32 settings:

  • 32kHz sampling rate & 1024 samples/frame --> 940.0ms frame roundtrip on serial

• Sampling Frequency vs TM4C Timer Period Mapping

  • 1 kHz: 79999
  • 2 kHz: 39999
  • 8 kHz: 9999
  • 16 kHz: 4999
  • 32 kHz: 2499
  • 48 kHz: 1665
