The best free EQ I've ever seen, better then some paid ones. Only thing missing is a preset saving and sharing feature.

Can't believe this is free. Extremely powerful, with features like independent side chain filter for each filter, and relative dynamic behaviour. Very intuitive workflow, and tool tips makes it easy to learn. Many thanks to ZL Audio.

Response from LuyuLiu from ZL Audio on December 30th, 2025

I am glad the tooltips and dynamic features are helping your process. Enjoy the plugin.

Nice lightweight EQ. Not sure in what situation I can need 16 bands but this fact itself is pretty pleasant)) The main pro of this EQ is its dynamic mode - otherwise I would be content with the native FL's Parametric EQ2. Thanks to the developer's advice about frequency titles - changing opacitt really helped!).

Response from LuyuLiu from ZL Audio on September 8th, 2025

I am glad that the suggestion is helpful :).

I hope the developers are reading this because I haven't found another ZL EQ forum. I recently updated my version from 0.3.5 to 0.4.3. I wanted to test it in Wavelab because I found a YT tutorial that I like. Especially a click on the icon on the top left led to the WL and ZL Qualizer being completely frozen. Is this known? I don't dare to test the plugin anymore.

Response from LuyuLiu from ZL Audio on November 27th, 2024

Thanks for reporting. No, this is not a known issue. If you double-click on the icon on the top left, the plugin should open the UI setting panel. Unfortunately, I am not able to reproduce it locally. Would you like to try the installer 'ZL.Equalizer-0.4.4-Windows-Software.exe' instead? If you still encounter the same problem, you may submit a bug report at https://github.com/ZL-Audio/ZLEqualizer/issues/new/choose (unfortunately, you will need a GitHub account) when you have time.

I will take it as a compliment :).

The first version of ZL Equalizer was released in March 2024 and the project has been free and open-source since day one. Do you have any evidence or specific parts of the codebase to support your claim?
