Ozone 9 has both analog and digital filter shapes such as, API-inspired proportional Q, band shelf, baxandall for boosting bass and treble, and resonant high and low shelfs. Equalizer in Ozone 9 also comes with two equalizer modules.

Track Referencing

A coordinated Vectorscope and Correlation Meter give you exact visual input to help control your blending and acing choices. Ozone Imager can limit or augment your soundtracks with basic controls, dazzling visuals, and mind blowing sound.


Browse the Triode and Dual Triode modes, or Retro, Tape, Warm, or Tube modes. Per-band Exciter modes permit you to pick a one of a kind bending mode for each piece of the sound range. With the exciter, you can still add your harmonics without having those who changes to your mix in sound with the Peak Saturation.
