Hi, based on user feedback requesting visual EQ curves, I have replaced the box indicators with real-time EQ curves. Now, every tweak to frequency, gain, or Q is instantly reflected in smooth, responsive curves.
Don’t worry, all the original features remain intact, and the audio processing is unchanged. If you are already using this EQ in your projects, everything works exactly as before.

Big thanks for all the feedback, it has made me appreciate this EQ even more.

Hi, Frequency and Q sliders now use a logarithmic scale for natural and more precise slider control, especially in the low end (of the frequency sliders) and in the lower values (of the Q sliders).

After careful consideration, I decided to remove one of the peak filters to free up space for the spectrum analyzer while also slightly reducing the plugin's vertical height. The updated design now features four peak filters (instead of the original five) while retaining the low and high shelf filters. This adjustment results in a larger, cleaner curve display area, enhancing overall readability without sacrificing essential functionality.

Hi, E-Equalizer300 has been updated to E-EQ300 with an improved interface. The original layout placed all sliders tightly together, which made it harder to visually distinguish between EQ bands. In E-EQ300, the sliders have been reorganized into visual groups to reduce clutter.

Changelog:
1. Plugin renamed to E-EQ300 to allow both versions to coexist. This ensures a smooth transition without disrupting your existing projects as slider numbering has changed.
2. Sliders have been reorganized into visual groups, making each band easier to identify and work with.

Note: Because the visual update required changes to the internal slider numbering, the old and new versions use different slider indices. So presets from the old version must be manually dialed into the new version.

Update:
Added band bypass buttons, great for quickly checking whether your filter settings are actually improving the sound. Click them to toggle band bypass on/off. They are also available for automation in the plugin parameter list.
Don't worry if you've already used the previous plugin version in your projects, all existing settings will be preserved.

1. Added a global plugin bypass button for toggling the EQ on or off without audio clicks.
2. Slightly increased the vertical range of the EQ curve to accommodate higher gain values.

[Windows]

UPDATE:
Hi, I have added channel mode options. You can now apply equalization in Stereo, Mid, or Side modes.

NB: Both the older and updated versions null 100% in a null test, as the underlying audio processing code and slider numbering remains unchanged. The new slider doesn't affect previous settings, so you can safely replace the old version with the new one in existing projects, and all your settings will be preserved.
