Bertom Audio EQ Curve Analyzer v2.1.3 VST3 AU AAX WiN MAC LiNUX [FREE]

EQ Curve Analyzer is a free utility plugin that lets you inspect the frequency response of any other plugin or hardware. You insert one instance before the device under test and one after: the first acts as a signal generator, the second as an analyzer. Adjust latency if needed, and the second instance displays the magnitude and phase curve of what’s in between. A group system lets you overlay two analyses on the same graph for real-time comparison. Because the measurement is isolated between the two instances, you won’t hear audio while capturing a response. It’s especially handy for learning how classic EQ emulations shape sound, or for checking what a piece of outboard gear is really doing. Available for Windows, macOS, and Linux in VST3, AU, and AAX formats, it suits hobby producers and anyone curious about the gear and plugins they already use. Note that it is an analysis tool only and does not process audio for listening.
