Perfect Pitch: Unveiling the Mathematical Symphony Behind a Guitar Tuner

Explore the intersection of music and technology with “Perfect Pitch,” an open-source guitar tuner built using React, Next.js, and the Web Audio API. This project dives into the fundamentals of pitch detection, covering techniques like zero crossing, Fast Fourier Transform (FFT), and the autocorrelation method, offering a practical implementation for both musicians and developers.

The talk explores the science and mathematics behind pitch detection, showcases real-world applications, and provides insights into improving the tuning process with noise cancellation and enhanced algorithms.

Designed with accessibility in mind, “Perfect Pitch” is a lightweight, browser-compatible tool that is easy to extend for developers interested in audio signal processing. Whether you’re a developer curious about DSP (digital signal processing) or a musician seeking a deeper understanding of tuning technology, this session offers practical knowledge and inspirational insights into the fusion of music and open-source innovation.
