Bertom EQ Curve Analyzer v1.3.7 VST3 AU AAX LiNUX WiN macOS [FREE]

Bertom EQ Curve Analyzer is a free audio analysis utility that reveals the frequency and phase response of plugins or hardware. Rather than shaping your sound itself, it helps you understand how another processor affects the signal passing through it. It is useful for hobby producers who want to explore EQ behaviour, study classic equalizer emulations, or compare processors beyond what their controls suggest.

To take a measurement, place the processor you want to test between two instances of EQ Curve Analyzer. Set the first instance to generate the test signal and the second to analyze the result. Adjust the latency if necessary to align the measurement correctly.

A built-in grouping system lets you display two analyses together on one graph and compare them in real time. This makes it easier to spot differences between EQ curves while changing settings. For producers working in a compatible Windows DAW such as FL Studio or Ableton Live, it offers a practical way to connect what you hear with a visual response.
