When you turn the knob to the right, you get more of that sound —the loud, hyped, in-your-face radio sound. It’s essentially a "loudness" button that actually works.
It takes the complex algorithms of multibanding, compression, saturation, and limiting, and boils them down to a single giant knob and four preset "A/B/C/D" curves.
How you get the plugin depends entirely on which Digital Audio Workstation (DAW) you use.
Since Soundgoodizer is an older plugin, modern Macs may block it. Open "Terminal" and type: sudo spctl --master-disable (Only do this after confirming the download is from the official source).
