What Plasma does

Unlike traditional saturators that apply a static effect to everything they touch, Plasma uses dynamic processing so the saturation can be shaped to the material. It identifies frequency areas that benefit from boosting and applies tube saturation only to those areas, which the developer presents as a way to keep a mix master balanced. Target Profiles, powered by iZotope machine-learning technology, guide the processing, and the Flux Saturation control sets the amount of coloration, with a sweet spot described as giving tracks what they need.

Channel Modes and Frequency Handles let the processing be focused on specific frequencies, mid and side channels, or transients, so the saturation can be placed exactly where it is wanted. The Overdrive fader adds extra crispy, crunchy character on top of the base saturation, and the developer notes that the sound can warm up gradually from the start. Searches pair the name with keygen and serial key, and a working serial is the string most often typed alongside the Plasma name.

Key features

• Dynamic frequency processing. Saturation is applied only to the frequency areas that Plasma identifies as needing boosting, instead of across the whole signal.
• Target Profiles. Target Profiles, based on iZotope machine-learning technology, guide how Flux Saturation is applied to the material.
• Flux Saturation and Character settings. Flux Saturation sets the amount of tube coloration, and the Character settings fine-tune the adaptive saturation, with an attack control among them.
• Overdrive fader. The Overdrive fader adds extra crispy, crunchy character on top of the base saturation.
• Channel Modes and Frequency Handles. Processing can be focused on specific frequencies, mid and side channels, or transients using the channel modes and frequency handles.
• Metering visualizations. The interface is organized around smooth metering visualizations that show the processing as it happens.
