Firechild offers four distinct models of the classic Vari-Mu Compressor, including three tube-based versions and a transparent clean mode. These models accurately replicate the original 1950s compressors, known for their unique dynamic control and tonal characteristics. Designed for use on master buses or individual tracks, Firechild brings vintage compression warmth and precision to modern productions.

This plugin is built on detailed sampling of real hardware units, capturing multiple stages of gain and compression through dynamic convolution technology. The three tube models provide rich saturation options that can be driven aggressively without immediate compression, allowing for a wide range of tonal coloration. Users can also tailor the compression response with six release modes, a knee control, and a bias control that influences tube saturation, adding depth and character to any audio source.

Beyond vintage emulation, Firechild includes modern tools like a comprehensive side-chain section with high-pass and low-pass filters, side-chain gain adjustment, and a mix knob for blending dry and compressed signals. These features enable precise shaping and creative control over the compression effect. Firechild performs excellently on mixes, mastering sessions, drums, vocals, and various instruments, and it comes with a collection of presets to jumpstart your sound design.
