ThrillseekerLA is a digital stereo leveling amplifier designed to deliver authentic analog character with smooth and dynamic gain riding. It operates with minimal inter-modulation distortion, thanks to its feedback compression design that avoids sample rate-based delays. The plugin features a simple control scheme with input level, gain reduction knobs, and manual attack and release adjustments, providing a wide range of envelope timing from instantaneous attack to extended release times of several seconds. Additional options include a mix level switch for optimal gain staging, customizable sidechain filtering to manage bass and high-frequency balance, and external sidechain support for flexible routing.

Beyond its precise compression capabilities, ThrillseekerLA incorporates a unique non-linear amplifier stage that imparts creamy, musical coloration. This stage employs custom algorithms based on a stateful non-linear saturation model that generates harmonic distortion dependent on compression and load. Users can control odd-order harmonic distortion and choose from six preset distortion profiles that offer diverse tonal characteristics such as warmth, enhanced top-end presence, and improved depth perception. The plugin also simulates authentic audio transformer effects, including low-frequency distortions and analog circuit behaviors influenced by frequency and load, enriching the overall sonic texture.

Compatible with Windows 32-bit systems supporting SSE2 or higher instruction sets, ThrillseekerLA integrates seamlessly into most VST hosts. Its advanced digital signal processing is optimized with assembler-level efficiency, ensuring high-performance operation. Released as freeware, this plugin provides a robust solution for musicians and producers seeking a high-quality analog-style leveling amplifier that combines precise control with rich, musical tone shaping.
