\\
**Description:** \\
"Reflects" the amplitude response of the selected curve through the 0 dB line, thereby inverting the frequency response variations.

\\
**Options:** \\
Minimum phase:\\
Linear Phase:

\\
**Use:** \\
To correct the frequency response of an input curve, which may be, e.g., a microphone or speaker driver response curve.

\\
**Example:** \\

The green curve represents the inversion of the input red curve, which as you can see is "mirrored" in the 0 dB line to obtain the green curve. Now, if the red curve is convolved with the green curve, the result obtained is a straight line at 0db, a flat frequency response.
