Each track starts as a mathematical sine wave at a fixed frequency. The live previews use the browser audio engine so you can hear the same frequency before buying.
The equation
simple by design.
A single frequency becomes sound by moving air in a smooth repeating curve. The product is intentionally minimal, so the tone can sit behind work, reading, rest, or sleep without musical movement.
Continuous tone
y(t) = A · sin(2πf · t)
Digital audio sample
y[n] = A · sin(2πf · n / fs)
- A
- 0.5 · -6 dBFS
- f

02
rendered long
The final files are rendered for 11 hours, 11 minutes, and 11 seconds, so a session can run without loop points, gaps, or restarts.
03
delivered clean
FLAC keeps the full lossless master. MP3 is included for phones, older players, and smaller storage. You keep both files after purchase.
Exact specs
what is in the file.
The specification is intentionally plain. The tone is not tuned to a hidden promise. It is background audio, made consistently and delivered as files you control.

Compliant by design
sound, not treatment.
StillTones does not promise health benefits, diagnose conditions, or claim that a frequency changes your body. These are steady audio files for people who prefer a quiet, simple background.
