Troposphere
Troposphere has the widest stereo image of any loop measured for these pages. The two channels are nearly uncorrelated and do not even share a dominant pitch: the left peaks near 89 Hz, the right near 350 Hz. It also swells more than the other pads. Best heard on headphones.

What the loop actually contains
Correlation between the left and right channels measures 0.07, where 1.0 would mean mono and 0 means the two are unrelated. In practice each ear receives largely separate material: an 89 Hz low tone dominates the left, while a 350 Hz mid dominates the right. Shared partials sit at 160, 304 and 1049 Hz. It also moves more than any pad here, with peaks around 13 decibels above its own median level, so it breathes rather than holding still.
How it compares and what to pair it with
Cosmic Drift takes the opposite approach, narrow and static, and Celestial Visions sits between the two. Singing Bowl is the only other file measured here with a comparably decorrelated image. The sound library index lists everything.
A wide, moving pad usually wants a steady centre under it. The Troposphere and pink noise blend in the free sound mixer anchors the middle while the pad moves around it.
Frequently asked questions
Why does Troposphere sound different in each ear?
Because it is. The channels measure almost uncorrelated, and their dominant pitches differ: roughly 89 Hz on the left and 350 Hz on the right.
Do I need headphones?
Not strictly, but the file depends on its stereo width, and a mono speaker collapses most of what makes it distinctive.
Is this a binaural beat?
No. A binaural beat needs two steady tones a few hertz apart, one per ear. This is a broad ambient pad with different material in each channel.
What causes the level to keep moving?
It moves more than any pad measured here, with swells about 13 decibels above its own median level.
