Some of the sounds in this player are real field recordings. Here is where they come from and how we use them.
The ambient recordings come from the 365Lab Noisemix open sound library, which collects royalty-free material originally published on Pixabay and Mixkit.
Both sources publish their sound effects under licences that allow free commercial use without attribution. Their licences prohibit reselling the raw clips as a standalone sound library — that is not what happens here. The recordings are embedded as part of a complete web player, which is a permitted use.
We list them anyway, because a page that plays other people's recordings should say so. A per-clip source list is maintained by the library itself at noisemix.365lab.top/credits.html.
Sixteen clips are used. Each is decoded in your browser, trimmed of its fade-in and fade-out, given a smooth loop point and matched to a common volume. The remaining sounds — white, pink and brown noise, binaural tones, the lullaby and the sleep music — are generated mathematically in real time and contain no recorded material.
