The Vocal-King plugin! It’s been my dream to make a Vocal Plugin. The idea of this plugin is to simply bring out the presence and clarity in vocals. This is free and only windows 32bit version. It is also way higher in CPU than the paid version. The paid version supports mac, windows, vst2, vst3, 32bit, 64bit. Feel free to email me at firstname.lastname@example.org if your country does not support PayPal or for price reduction if needed.
