If you have a calibration file, send it together with the recording in the version corresponding to your use (ie version at 90° if mic was used vertically, as recommended). If you have no calibrated mic, choose None/flat. Important : the calibration file is the response of the microphone, not the correction to apply !
For Umik, send the manufacturer cal file. The level reported in the graphs is calculated with the recommended 18dB gain of the Umik together with the sensitivity from calibration file (this is important for multichannel movie setups to be in conformity with SMPTE standards).
For “Other”, send a file named “calibration.txt” with first line at 0Hz and last line at 24000Hz, with a space between frequency and level such as :
0 -20
20 -0.1
1000 0
20000 0.1
24000 -20
Decimal separator should be “.” (dot) and not “,” (comma)
Your calibration files will be processed and saved as “response.mic” in the same folder. If you are sending new recordings the same day for the same studio, you don’t need to send the mic calibration file again.
If your calibration fike is not valid, it will be replaced by a flat mic response, same as without any cal file.
