The C-C- -01 is a signal enhancement VST plugin designed to refine and elevate audio signals with a comprehensive suite of processing tools. Featuring a 7-band EQ and multiple filtering options, it allows precise tonal shaping and frequency control. The plugin incorporates dual peak followers with RMS and oscillator-based inputs, enabling dynamic modulation of the signal's volume response. Users can adjust attack and decay parameters to tailor transient behavior, blend wet and dry signals, and integrate saturation for added warmth and character. Its stereo processing includes mid/side splitting, with independent control over each channel and linked adjustments for streamlined workflow.

C-C- -01 presents unique features such as non-EQ makeup gain controls, which subtract the EQ signal and blend back the original frequencies, allowing creative sound design options. Oversampling is available up to 32x to enhance audio fidelity, though it remains active even when the effect is bypassed. The plugin provides flexible saturation settings with multiple saturators that can be independently driven and blended, offering nuanced distortion effects. Additionally, users can utilize oscillator and noise sources to influence peak following behavior, adding subtle equalization and clarity enhancements. The interface supports precise knob and slider control through modifier keys, making detailed adjustments more accessible.

While built with SynthEdit, the C-C- -01 plugin delivers a distinct signal processing experience with a focus on enhancing clarity and presence in mixes. It supports 64-bit Windows systems as a VST3 plugin and offers features like channel isolation, linked controls, and customizable response curves. Some limitations include the absence of sidechaining and an internal preset browser, with potential automation challenges depending on the host DAW. Despite these, it remains a powerful tool for producers seeking to add subtle or pronounced enhancements to their audio tracks, blending EQ, dynamic control, and saturation into a single package.
