1Select oscillator mode: Pure Tone (Sine/Square/Saw/Triangle), Binaural Beats, or Colored Noise
2Adjust target frequency (20 Hz to 20,000 Hz) using the slider or pitch presets (440Hz A4, 432Hz)
3Inspect real-time waveform oscillations on the HTML5 Canvas oscilloscope
4Toggle audio playback and adjust safe volume levels directly in your browser

Audio State:IDLE / MUTED

Audio Synthesis:Web Audio API

Oscilloscope:2048-pt FFT Canvas

Sample Rate:44.1 / 48 kHz

•Keep volume modest when testing high frequencies above 8,000 Hz to protect your hearing
•Binaural beats require stereo headphones because two slightly offset frequencies are routed to each ear
•Pink noise has equal energy per octave, making it the industry reference for room acoustic calibration

Input
