Tone Generator & Visualizer

🔧 Tone Generator & Visualizer is a high-precision electrical test and measurement tool designed for engineers, technicians, and developers working with audio hardware, circuits, and embedded systems.

This app acts as a mobile signal generator and oscilloscope-style waveform visualizer, enabling real-time generation and analysis of electrical audio signals across a wide frequency range.

⚙️ Key Applications:

Testing audio amplifiers, speakers, microphones, and signal paths

Validating frequency response and gain structures in hardware setups

Simulating test tones for electronic calibration and diagnostics

Performing oscilloscope-style waveform comparison

Field testing in environments where portable lab tools are required

🎛️ Core Features:

Generate multiple independent test tones

Four waveform types: sine, square, triangle, sawtooth

Full frequency (Hz) and amplitude control per signal

Real-time visual feedback with waveform rendering

Signal overlay support — combined waveform visualization

Frequency range from sub-bass (~20Hz) to ultrasonic (>20kHz)

Minimal latency, high stability, and accurate output

Optimized for mobile and tablet displays

🧰 Use this tool as a:

Frequency generator for lab environments

Reference tone source during hardware development

Lightweight audio test bench in your pocket

Digital test equipment replacement for quick diagnostics

🔬 Whether you’re tuning a circuit, diagnosing signal integrity, or calibrating components, Tone Generator & Visualizer delivers the precision and clarity needed for professional-grade electrical audio testing.

📲 No internet connection required. Always ready when you need accurate, reliable audio signal generation in the field or lab.
