bioacoustic-visualizer

A collection of Python-based scripts designed to transform audio recordings into visual representations (MP4/GIF), through digital signal processing techniques.

Visualizer 1

α 3D peak frequency per frame

Generates animated 3D pitch trajectories from bioacoustic signals. This script calculates STFT, extracts peak frequency/amplitude data over time, and renders a smooth, rotating 3D animation with live frequency tracking.

Visualizer 2

β radial mapping deep dea echolocation sonar visualizer

Instead of a 3D spiral, this script maps time to a circle (like a radar sweep). The amplitude of the clicks violently spikes outward from the baseline, and the frequencies dictate the color of the bioluminescent "bursts." As the audio plays, a radar playhead sweeps around the circle, leaving a glowing trail behind it, with dynamic typography in the center.
