Peak Rider by Impact Soundworks is a dynamic processing plugin designed to reshape how volume envelopes interact with audio signals. Instead of functioning like a conventional compressor or expander, it uses a sidechain input to generate a new volume contour for the main audio source. This approach allows the main signal to adopt the dynamic character of the sidechain, enabling unique mixing possibilities and creative sound shaping that bring static audio to life.

The plugin features multiple processing modes including Exact, Noboost, Duck, and Limit, each offering distinct volume-based effects that can be tailored to fit a variety of audio contexts. Both single and multiband processing are supported, providing flexibility for detailed dynamic control across the frequency spectrum. Additional controls like Range and Mix allow users to fine-tune the intensity of the effect, while stereo processing options include left/right and mid/side modes with linked or independent channel treatment.

Peak Rider delivers precise, sample-accurate analysis with zero latency, and offers minimum and linear phase processing modes to suit different mixing needs. Compatible with Windows and macOS, it works in VST and AU formats with 32 and 64-bit support. The plugin employs a straightforward serial number system for copy protection and comes with a full demo version, making it accessible for producers seeking an innovative tool to dynamically enhance their mixes.
