EQ Curve Analyzer

EQ Curve Analyzer measures the frequency response of an audio path or processor. It is useful for examining what an equalizer or other linear signal path does, rather than relying only on a displayed control curve. Routing and test conditions matter. Nonlinear or time-varying processors may need different interpretation, so avoid treating one response trace as a complete description of their sound.

A useful display begins with a clear question and appropriate measurement settings. Confirm important observations through listening or a second check, and document calibration where absolute measurements matter.
