White Noise River for sleep• San River, Bieszczady • Black Screen • 12H

12 hours of river white noise for sleep — no loops, no music, no AI. Black screen. Recorded on the San River in Bieszczady, Poland. Clear water flowing over rocks, mid-pace current, full sun, no wind, no traffic. Primary microphone: Sennheiser MKE600, background: Rode NT1, recorder: Zoom F3 with blimp windscreen. Designed for screen-off use — put the phone face down or close the laptop and let the audio run overnight. The 12-hour runtime covers a full night without looping back. No music, no noise reduction, no AI — a real field recording.
