Linear Phase Frequency Crossover for Modular Hosts is a specialized audio tool designed to split incoming signals into two distinct frequency bands with precision. It operates with a single input and two outputs, allowing for clear separation of low and high frequencies. Users can select the crossover frequency to tailor the audio signal division according to their project needs.

This crossover uses linear phase filtering to maintain the phase integrity of the signal, ensuring minimal distortion and preserving the sound's natural quality. The filter employs 512 FIR coefficients, which can be increased upon request, providing detailed control over the crossover characteristics. Its processing is optimized for speed and accuracy, independent of the sample rate, making it suitable for various audio production environments.

The plugin is open source, except for parts utilizing specific performance libraries, and integrates seamlessly with modular hosts through its host-dependent graphical interface. This design allows it to adapt visually and functionally within different software environments, offering flexibility and efficiency for audio engineers and producers seeking precise frequency band division.
