We developed an audio spectrum analyzer as our final project for ECE 4760. This analyzer presented a histogram-style representation of audio signals. We successfully achieved real-time display of the audio signal’s frequency spectrum using a monochromatic histogram layout, where bins extended from left to right, representing low to high frequency ranges. Our system was built […]

When it comes to recording audio in wildlife or nature, you require something with a small form factor that does not harm the environment. There are several wildlife species that produce noise in ultrasonic frequencies like bats, moths, etc. Here comes the name for the credit card-sized open-source sound recording device âÎźMothâ â designed to listen to audible

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.
