10 Hours Of Blue Noise, Black Screen (For Sleep, Study, Relaxation)

WHAT THIS IS Blue noise — also called azure noise — is the mirror of pink: its power rises by 3 dB per octave, so it sounds bright. Measured on this file: 3.1 dB per octave from 100 Hz to 10 kHz. HOW IT WAS MADE Ten hours generated by this channel's own code from a seed (seed 148, streams 8 and 9) — nothing recorded, nothing fetched, no sample library. Two independent channels at 48 kHz, so the left and right ears hear different noise of the same colour. White Gaussian noise through pink's cascade with its poles and zeros swapped, whose average slope is +3 dB per octave. A five-second fade at each end. Loudness measured on the finished file: -23.0 LUFS integrated, true peak -13.1 dBTP, loudness range 0.0 LU. Duration 10:00:00. This describes what the noise is and how it was made. It makes no claim about what it does for anyone. Every figure above was measured on the finished file, not assumed.
