I have an audio signals from two microphones, and I have to make them equal for equal input. I.e. calibrate the output of microphones to give the same resulting signal on both of them. The problem is with amplitudes. Both sensors aren't equaly sensitive (logically. But I need the output to be.
The naive solution of this problem would be to find a constant difference between signal from mic A and mic B. And simply add it to the signal that requires that boost.
But, well, I am introducing deviation to signal. I am pushing it up along Y axces. This increases the top amplitude, but I am increasing the silence too.
Well, signal will not really change, on speaker will be heard the same, as silence line continues to be the line,
but I don't see what other implications I may have if I do this.
How would this affect the frequency spectrum for instance.
Note: I cannot do:
normalization because I loose the info about initial amplitude of the signal. My measurement uses amplitudes and they must stay as they are, except that microphones should be calibrated.
