A different perspective on water
The credited “Underwater” source by Joseph SARDIN and Axeline T. describes a waterfall recorded with a hydrophone. A hydrophone records sound in water; it is a different recording perspective from a microphone beside a stream.
The player repeats a 30-second prepared excerpt. Its source context is freshwater at a waterfall, not an invented reef, submarine or open-ocean location.
Compare underwater and surface recordings
Listen at a comfortable level on your usual equipment. Compare this recording with Stream or Ocean to hear the difference between a below-surface perspective, flowing surface water and shore waves.
A phone speaker and larger speakers may present low-frequency detail differently. Adjust the sound to your equipment rather than treating the volume percentage as a calibrated output level.
Keep the water distinct in a mix
Try Underwater alone before blending it with Night or Forest in the mixer. Bring a second layer in quietly so you can still tell what the underwater recording contributes.
These layers have independent origins. Mixing them makes a new soundscape, not evidence that an underwater and land recording were captured in one place.

Recordings & sources
The player repeats the short audio files below for as long as your session runs. The loop length is the length of each file, not a limit on listening time. Events within a recording may repeat.
| Sound | Loop | Source |
|---|---|---|
| Underwater | 30 s Mono | Joseph SARDIN & Axeline T. Field recording · CC0 |
Start at a comfortable level. The volume percentages describe player settings; they do not measure the sound level at your ears. Playback with a locked screen or a background tab depends on your device and browser. Opening another page stops playback.
Common questions
Was this recorded in the ocean?
The source describes an underwater waterfall recording made with a hydrophone. We do not claim that it came from the ocean or a named dive location.
Is underwater the same file as stream?
No. Stream is a separate surface recording of a small mountain stream. Underwater uses its own original recording and prepared audio file.
Can I use it as a background with a timer?
Yes. Adjust Volume, choose a timer and press Play. The clip repeats while the session runs; background playback can be interrupted by your browser or device.
