A browser-based tone generator built with the Web Audio API

Hacker News

I built maketonesonline.com — a simple browser-based tone generator to experiment with the Web Audio API. What it does: Generates tones from 20 Hz to 20,000 Hz Supports sine, square, triangle, and sawtooth waveforms Lets you adjust frequency, volume, and left/right stereo pan Includes multi-tone, binaural beat, subwoofer/bass frequency, and sweep tone modes It’s useful for testing speakers, hearing tests, exploring sound design, or just seeing how high a pitch you can still hear. Check it out: https://maketonesonline.com I’d love your thoughts, bug reports, or ideas for improvement!
