Black Screen | AC Noise | 10 Hours | Calm Flat
A calm, flat AC hum remains constant across a black screen with no sudden changes.
Precisely engineered black screen and AC-style noise designed for long, uninterrupted rest.
▣ Audio Specification
• Optimized for long-form continuous playback within a calibrated loudness range (-19 to -21 LUFS)
• True peak carefully controlled below approximately -1 to -2 dBTP
• 10-hour master rendered through a high-resolution PCM workflow (48 kHz class)
▣ Processing Profile
• Low-frequency stability management using sub-bass filtering (approx. 20–40 Hz)
• Upper-band softening applied to reduce fatigue across the high presence region (12–18 kHz)
• Subtle mid-range tone shaping (±1 dB range) for consistent AC-style hum character
• Stereo field refinement using micro-delay imaging in the ~5–15 ms range
• Gentle RMS-linked compression with low ratios (approx. 1.2–1.6:1) for overnight comfort
• Final leveling performed with broadcast-grade 2-pass loudness normalization
• Mid/Side balance calibrated with slightly reduced side energy (approx. 2–4 dB attenuation)
▣ Production & Authenticity
• All audio and visuals in this video are fully self-produced by Sleepy Hum.
🌙 Experience calm, steady AC-style hum for deep rest — only on Sleepy Hum.
