PLP Beat Tracker Visualization

Visualization of a PLP based Beat Tracking algorithm!

This is the result of a project I've worked on where, after reading a research paper, I create visualizations of the different steps that are part of a PLP Beat Tracking algorithm.

The research I'm referring to is

Peter Meier, Ching-Yu Chiu, and Meinard Müller
A Real-Time Beat Tracking System with Zero Latency and Enhanced Controllability
Transactions of the International Society for Music Information Retrieval (TISMIR), 7(1): 213–227, 2024

There are 3 ways to run the project:

1. PLP Visualization: It's the main visualization mode that shows the AudioData graph, the activation, the tempogram, and finally, the PLP graph. It also has a funny cat clapping his hands along beats with a stability greater than a certain threshold.
Once selected a file explorer will popup asking you which song you want, navigate to the desired folder and double click to select.

2. Microphone Mode PLP: It's basically the same thing but it will use your microphone instead of an audio file.

3. Frequency Graphs: A simple visualization I created to test out the graphs that shows how different frequency ranges change with time.

You can also check the repository of this project, where all code is public: https://github.com/AlessTheDev/plp-beat-tracker.

I've also made a "devlog" where I explain how I coded this in detail: https://medium.com/@cupflowstudios/analyzing-real-time-audio-data-with-unity-plp...
