Can I use this white noise generator offline without an internet connection?
Yes, once the White Noise Generator page has fully loaded in your browser, it can continue to play sounds even if your internet connection drops. Since the noise is generated directly within your browser and not streamed, you won't experience interruptions. Just ensure the tab remains open and active for uninterrupted relaxation or focus without needing an active internet connection.
Can I record the white noise generated in my browser for use in my podcasts or video projects?
Yes, you can record the white, pink, or brown noise generated by this tool for personal use in creative projects like podcasts, background ambience for videos, or meditation tracks.
