The missing spark
Plasma is like futuristic car polish for your audio. Its tube saturation is adaptive to your audio, not static like others. I made a lifeless B3 track instantly come to life. Loving it on my instrument buss as well. An innovative tool for the future. Well done, iZotope.
Rob Dennis, GRAMMY-winning engineer (Jelly Roll, Carrie Underwood, Fisk Jubilee Singers)
Plasma is truly magical. It's my new to go-to plugin for adding harmonics to anything. It brings forward the harmonics you want without the harshness, and without sounding overly distorted. Truly incredible.

I explored the new Plasma plug, and WOW is the best one word description! I tried it on several tracks in a recent mix and it seemed to make almost everything...just sound better.
