%description
This repository hosts a pitch detection application designed for Linux systems,
specifically tailored for guitar input.
The underlying methodology is based on complex resonators and is optimized for
accurate pitch estimation. The theoretical foundation of complex resonators
can be found in the article titled "A Computationally Efficient Method for
 Polyphonic Pitch Estimation" authored by Ruohua Zhou, Joshua D. Reiss,
Marco Mattavelli, and Giorgio Zoia.
The system is currently in a developmental phase to incorporate frequency domain effects.
