Bertom EQ Curve Analyzer is an analyzer & signal generator plugin to see the frequency and phase response of any plugin (or hardware).
Insert the plugin you want to analyse between two instances of EQ Curve Analyzer, the first one set as a signal generator and the second one as an analyzer. Then adjust the latency if needed. That’s it!
It is particularly useful as a learning tool to see what classic EQs emulations are doing for example. It also features a “group” system that enables to compare two analyses in real-time on the same graph.
