EQ Curve Analyzer is a powerful tool designed to visualize the frequency response, including both magnitude and phase, of any audio plugin or hardware device. By providing clear graphical feedback, it helps users understand how their audio processors shape sound, making it an essential addition to any mixing or mastering setup.

The plugin operates by placing two instances around the device or plugin under test: one configured as a signal generator and the other as an analyzer. This setup allows for real-time measurement of frequency response, with adjustable latency settings to ensure accurate results. The straightforward workflow makes it easy to incorporate into any audio chain.

EQ Curve Analyzer also includes a group feature that enables users to compare two frequency responses simultaneously on the same graph. This capability is especially helpful for studying classic equalizer emulations or evaluating different processing options side by side, providing valuable insight for sound design and educational purposes.
