- size FFT 4096 or 8192 ( frequency resolution 10,7 Hz or 5,4 Hz )
- Fast or Slow time weighting ( t = 1 sec and 0,125 sec )
- enable A, C, or ITU-R 468 frequency weighted

This App allows you to enter a correction (calibration) AFC, to account for the uneven frequency response of the microphone and recording device path.
