TonalTrackSpacer is an innovative audio plugin designed to create space in your mix by applying an inverse equalization based on an external signal. Unlike conventional frequency-based tools, it operates using musical notes, allowing for a more musically intuitive approach to frequency attenuation. This method helps to carve out necessary sonic space efficiently, making it easier to separate instruments or vocals within complex arrangements.

The core functionality relies on controlling multiple EQ Eight filters, each positioned at a different octave, which respond dynamically to incoming audio and MIDI signals. With eight detection filters corresponding to eight octaves, TonalTrackSpacer adjusts both frequency and gain parameters in real-time according to the detected notes. This targeted filtering reduces the need for numerous EQ bands, optimizing CPU usage while maintaining precise control over the mix elements.

Flexibility is a key feature, as the plugin can be used with or without MIDI input, enabling single-note settings or full dynamic responses. A manual mode offers detailed control over detection and equalization filters, while adjustable detection sensitivity and filter response speed allow users to tailor the effect to various production needs. Additional options include modifying EQ filter modes and inverting control values to boost frequencies instead of attenuating them, expanding creative possibilities within the mixing process.
