Spectrum 3D

Spectrum3D is a real-time audio spectrum analyzer for Android that visualizes microphone input through stunning bars, 2D waterfall, and 3D surface plots using advanced FFT processing. Customize FFT sizes, overlap, scroll speeds, and normalization for optimal analysis, with smooth OpenGL ES rendering and intuitive touch controls. Perfect for audio enthusiasts, musicians, and engineers.
The Spectrum 3D benefits:
- Real-Time Audio Analysis: Captures and analyzes microphone input using advanced FFT processing for live spectrum visualization.
- Multiple Visualization Modes: Supports bars, 2D waterfall, and 3D surface plots with customizable rendering options.
- Adjustable FFT Settings: Configurable FFT sizes (up to 8192), overlap, and hop-based processing for optimal frequency resolution.
- Visualization Controls: Halveable scroll speeds for waterfall, normalization windows for contrast adjustment.
- OpenGL ES 3.0 Rendering: High-performance graphics with custom shaders for smooth, immersive displays.
- Touch Interaction: Intuitive controls for zooming, panning, and switching between visualization types.
- Persistent Settings: Saves user preferences (FFT sizes, speeds, normalization) using DataStore for consistent experience.
