    Introduction. This project implements a real-time audio spectrum analyser using a PIC18F4550 8-bit microcontroller. The spectrum frequency analysis is performed by a highly optimised 16-bit Fast Fourier Transformation (FFT) routine coded entirely in C. The output from the FFT is displayed using a 128×64 graphical LCD to allow a real-time view of an audio signal.

Audio Spectrum Analysis - Pico Technology

    https://www.picotech.com/library/application-note/audio-spectrum-analysis
    Advantages of Pico products for audio spectrum analysis. Spectrum analyzers tend to fall into two categories: so-called ‘swept’ spectrum analyzers and FFT-based spectrum analyzers. Swept spectrum analyzers work by using one or more notch filters (or mixers) to measure the signal amplitude at a given frequency, and by changing (or sweeping) the frequency of this filter a plot …
