## What it is
Horizon is an Android library that renders a smooth, animated visual equalizer of live audio using OpenGL ES and C++ sound analysis. It draws layered Bezier-curve waves that react to audio frequencies, suitable as a music visualizer component in Android apps.

## Use cases
- visualize audio playback as animated waves in an Android app
- add a music visualizer to a voice recorder screen
- display a live equalizer while recording audio
- render frequency-based wave animations with OpenGL ES on Android
- customize an audio visualizer component for a music player

## When to choose
- you need a polished, animated audio visualizer for an Android app
- you want GPU-accelerated wave rendering rather than slow Canvas drawing
- your project is Java/Android and you want an easy-to-customize equalizer view

## When to avoid
- you need an audio processing or DSP engine rather than a visual component
- you target platforms other than Android
- you need a library with an explicit license or active maintenance guarantees
- you want a prebuilt app rather than an embeddable UI component
