About the sounds

Brown, pink, and white noise are generated continuously on your device. Mix levels and the seven EQ bands change the sound live, with smoothing to avoid clicks. Brown noise rolls off higher frequencies for a warm, low sound; a rumble filter removes subsonic energy. A compressor controls peaks from strong EQ boosts. Use your device volume for listening loudness.

First-version notes

This version uses Web Audio for live sound, so locked-screen playback needs testing in Safari and installed mode. When you return after an interruption, the app tries once to resume your active session. If the browser blocks it, tap Resume. Deliberate pauses stay paused. A detected audio-device change requires manual resume. Your timer keeps its original end time; recovery does not extend it. No recordings or loop buffers are used. Timers fade on the audio clock while the engine is running; interruptions may affect timing. This is a sound player, not an alarm.

Preferences stay on this device. Google Analytics measures visits and completed app actions. Microsoft Clarity provides interaction heatmaps and session replays. User-entered mix names are excluded from our Analytics events and masked in Clarity. No ads, payments, or account sync are connected in this version.
