About SLNC
SLNC is a free, browser-based noise mixer designed to help you create personalised ambient soundscapes. No downloads, no sign-ups just open the page and start mixing.
What Is a Noise Mixer?
A noise mixer lets you blend different noise colours to shape the sound environment around you. By adjusting the volume and frequency filters of each layer, you can craft a soundscape that suits your needs whether that's concentrating on a task, winding down before sleep, or simply masking distracting background sounds.
Why SLNC?
SLNC is built to be simple, fast, and distraction-free. There are no ads, no accounts. Everything runs directly in your browser using the Web Audio API, so your sound preferences stay private. The mixer gives you precise control over three noise channels with adjustable frequency filters and individual volume sliders, plus a master volume to balance everything at once.
