okay, i might be dumb... but what's the difference between this equalizer and ZL Equalizer 2?
i mean ZL Equalizer 2 and this one looks exactly the same to me. is there a difference?
i didn't find any mention of the difference in the documentations on the plugin manuals, so i thought here will be the next best place to ask this...

also thanks for making these awesome plugins <3

ZL Equalizer 2 mainly processes on the time-domain via IIR filters. Here is the dynamic part manual of ZL Equalizer 2: https://zl-audio.github.io/plugins/zlequalizer2/manual/#dynamic-filter

ZL Spectrum Equalizer 2 completely processes on the frequency-domain via FIR filters (FFT & IFFT). Here is the dynamic part manual of ZL Spectrum Equalizer: https://zl-audio.github.io/plugins/zlspeceq/manual/#spectrum-dynamic

In most cases, you should reach out to ZL Equalizer 2. But when you need pure linear-phase filters or resonance control, you should use ZL Spectrum Equalizer.
