Mix and layer ambient sounds like rain, thunder, wind, birds, and cafe chatter with individual volume sliders.
The Ambient Sound Mixer plays a small set of looping ambient tracks - rain, thunder, wind, birds, cafe chatter - each behind its own volume slider, so you build a custom blend instead of picking a single preset track. Push one slider up to bring that sound forward, pull another down to fade it out, and run several at once. What catches people off guard is that nothing gets exported: there is no download or file produced, the mix only exists while the tab stays open and playing, and it resets to silence on reload unless the page happens to remember your slider positions.
Each ambient sound is its own looping track with a dedicated slider, typically running from silent to full volume. Sliders act independently, so raising rain and lowering cafe chatter at the same time changes only those two layers; the others keep playing at whatever level you left them, and several loops sum together into one blended output.
Mixing happens live in the browser tab rather than producing a rendered file, so the sound only exists while that tab is open and unpaused. Switching away, closing the browser, or letting the device sleep can interrupt it, and mobile browsers often pause background tab audio when the screen locks or another app takes focus.
No, not as far as this tool is built for - it is a live playback mixer, not an audio renderer. There is no export step that writes a WAV or MP3 of the blend, so if you need a portable file you would have to record the output separately.
That depends on the device and browser's background-audio rules, not on the mixer itself. Many mobile browsers suspend audio in a background tab once the screen locks or focus moves elsewhere, so treat this as a foreground, tab-open tool rather than a reliable background player.
