    BTW What microphone is this calibration file for? Between 20 Hz and 20 kHz, the file has a range of approximately -17 dB to +10 dB, and with an approximately 15 dB jump just above 16 kHz. This seems way too much variation for a measurement microphone. I would expect something in the range of -3 to 3 dB, and with very minimal phase change.
