216 Hz Warm Tone | 1 Hour of Space Relaxation

Settle into one hour of a quiet 216 Hz sine tone over a soft noise bed. Space equipment footage plays throughout, with a slow fade in and out. Part of Space Journey by Quantumsatisfaction. Original synthesized audio accompanies selected NASA footage, slowed and looped forward and backward for a calm visual rhythm. This is a creative edit, not an uninterrupted mission recording; the sound is not recorded spacecraft audio. 216 Hz identifies the tone used in this soundscape. Frequency labels describe the audio, not proven healing effects or a guarantee of sleep. Listen at a comfortable volume. No narration or sudden alarms.
