Chordal 1.2.2

This application utilizes the microphone to analyze incoming sounds and visually represent their overall frequency content. Designed as a musical visualization tool, it aids users in exploring pitches, harmonics, and harmonic relationships.

From a technical perspective, the app employs a standard FFT (Fast Fourier Transform) algorithm, which is displayed through a color-coded spectrum. The visual feedback is overlaid on a black and white keyboard calibrated to A440Hz. It encompasses a range of notes from C2 (65Hz) through B7 (3951Hz), using octave band segmentation.

In practical terms, the keyboard highlights areas where pitches are detected, allowing observers to see variations such as vibrato or pitch bending. This feature accommodates a broad spectrum of instruments, making it a versatile tool for musicians and educators alike.
