Owner-approved CC0 field recordingRushing RiverThe real Magdalena River near Los Dinamos, south of Mexico City, was recorded in stereo by orlandorizo with a Zoom H5N. Strong continuous water rush rather than individual gentle drips.

Owner-approved CC0 field recordingBodetal Brook & BirdsAn authentic stereo field recording from Bodetal, Harz/Thale, Germany. Recorded by Borgory using a Zoom H5, this source captures a distant flowing stream and birds, not an artificially generated or close-mic bubbling brook. The owner-approved ten-minute MP3 master selects approximately 605 seconds of independent recorded source; extended sessions repeat the ten-minute cycle.
Owner-approved CC0 field recordingCrashing Ocean WavesAn authentic stereo coastal field recording of breaking waves at Wakanui Beach near Ashburton, New Zealand. The original 45-minute sound was captured by Desmond178 and released under CC0. The owner-approved ten-minute MP3 master selects approximately 605 seconds of independent recorded source; extended sessions repeat the ten-minute cycle.

Existing canonical sound pages, the seven intent collections, continuous playback, Sleep Timer and 45 current mixes remain unchanged. Planned IDs are scheduling identifiers only; no sound is created by listing it here.
How to choose a sound
Choose a noise color for a uniform synthesized background, or explore machine-like and environmental textures for a more specific listening character. Sound labels distinguish independent original DSP from field recordings and disclose when a ten-minute arrangement was built from a shorter source.
All available sources have their own page and continuous listening controls. A file that passes automated checks may still require subjective approval for long sessions; planned sounds are never presented as playable masters.
