Free Online Frequency Generator: Professional-Grade Audio Synthesis
What Is an Online Frequency Generator?
An online frequency generator is a web-based tool that produces audio tones at specific frequencies. These tools are used for sound testing, meditation, research, and more. Unlike hardware generators, online solutions are accessible from any device with a browser.
How the Web Audio API Works
The Web Audio API is a powerful browser feature that allows precise audio synthesis. It supports real-time generation of sine, square, triangle, and sawtooth waves, as well as frequency sweeps and modulation. Researchers have explored its use for wellness and sound therapy, and some users report positive outcomes.
Waveform Types Explained
- Sine: Smooth, pure tone. Common for meditation and research.
- Square: Sharp, buzzy sound. Used in some frequency protocols.
- Triangle: Softer than square, but with more harmonics than sine.
- Sawtooth: Bright, rich in harmonics. Used in audio testing.
