Join me on a musical journey through the world of open source software as I share the story behind crafting from scratch an online guitar tuner with Javascript.

In this talk, we'll explore the delightful intersection of mathematics and development, where a simple curiosity led to the creation of an open-source tuner using React and Next.js.

I'll share insights and challenges into the implementation of the tuner, navigating through the algorithmic landscape of autocorrelation and frequency calculations.
