Remove Noise is Wavli’s main tool. It’s one automatic cleanup for steady background noise: the hum of a fan, air conditioning, a computer, a fridge, or constant room hiss. You don’t pick a noise type; Wavli works out what to remove.
You control how hard it works with the Strength slider, from Natural to Strong. Natural keeps more of the room’s character and is gentler on voices. Strong removes more noise, and you’ll hear quickly when it starts to affect the voice. Before you commit, tap “Preview 8 seconds” to hear the result, adjust, and preview again. Previews are free.
When it’s done, Wavli shows Before and After players so you can compare the two. Then export the cleaned file as M4A, WAV, MP3, or AIFF, or as MP4 if you started with a video.
Remove Noise runs entirely on your iPhone. It works on voice memos, interviews, lectures, podcasts, and the sound of your videos.
What it isn’t for: echo and room reverb, clicks, pops, and crackle, or other people talking in the background. Those need a different fix, and it’s better you know before you start.
