## Description

Spectroid is a powerful real-time audio spectrum analyzer designed for detailed frequency analysis across the entire audio spectrum. It employs multiple overlapping FFTs to enhance frequency resolution, especially at lower frequencies, delivering a spectrum visualization that closely aligns with human audio perception.

Key features include zooming functionality via two-finger pinch gestures, real-time spectrum and waterfall plots, and intuitive display of decibel levels using dBFS (where 0 dB corresponds to maximum microphone input). While it provides insightful audio analysis, Spectroid is not intended as a calibrated instrument for official data export, rather as an accessible tool for audio enthusiasts and professionals alike.
