White Noise Generator

Choose a noise color, adjust volume, use a sleep timer, and keep audio generation local to your device.

Noise shaping, presets & fade timer

The fast white/pink/brown player above remains first. This optional workspace reuses the existing local noise buffer, adds masking presets, low/high-cut shaping and a gentle fade-out timer while keeping playback entirely in Web Audio.

Practice and playback notes

connects timing, tuning, pitch reference, virtual instruments and music-theory tools without requiring an account. Existing interactive engines remain intact while the new workflow makes it easier to move from a practical task—keep time, tune, play, identify, transpose—to the next relevant tool.

Audio and theory boundaries

Microphone pitch detection depends on the device, room and signal quality. Equal-tempered frequency math does not measure a real instrument, and chord/scale naming can have multiple enharmonic or theoretical interpretations. Reference tones and noise should be used at comfortable playback levels; browser controls do not measure sound-pressure exposure.

Practical guide and verification

Use the tool first, then apply these checks to verify the inputs, interpret the result, and hand it off without displacing the primary workflow.

Use comfortable playback levels

Noise color changes spectral balance, not safe listening limits. Start with the device volume low and raise it only as needed. Browser volume sliders do not measure sound-pressure level at your ears, so avoid treating an on-screen percentage as a hearing-safety reading.

Match the noise color to the masking task

White noise carries relatively more high-frequency energy, pink noise tilts downward, and brown noise is heavier in the low end. The most useful choice depends on the unwanted sound, speakers, room, and listener preference. A softer-sounding color is not automatically safer or more effective.

Use filters to shape, not to claim treatment

Low-cut and high-cut controls can reduce rumble or hiss and make a masking signal easier to tolerate. They do not diagnose tinnitus, improve sleep medically, or replace professional advice. Save the exact color and filter settings if you are comparing sessions.

Verify timer and fade behavior on the actual device

Background tabs, battery-saving modes, audio-route changes, and browser suspension can affect timing. If the stop time matters, test the fade on the same browser and device you will use and keep a separate alarm for time-critical reminders.
