This folder contains the accompanying software (control panel) for the Umik-2 USB microphone.
The software allows to control the analog preamplifier of the microphone, setting its gain
in the range 0 dB => + 42dB at 1 dB steps.
For normal usage the microphone should be left with a 0 dB gain, so that the clipping
limit of the A/D converter equates the clipping limit of the capusle, 130 dB SPL.
The microphone is usually sold preset with a gain of + 18 or +20 dB, which reduces
the clipping limit to just 110 dB SPL. Such a setting is NOT suitable for measuring
high SPL values, resulting in waveform clipping and distortion.
So it is almost mandatory to reset the gain to 0 dB before using the Umik-2 for calibrated
SPL measurements.
It is unclear why MiniDSP does not provide this gain control panel to all users.
But here it is!
