Having a denoiser option would be great, though I'm not sure if this is possible on an iphone. Does anyone know of an app that does this (like neat video but for ios).

Even adding some of the AU3 pliggins would also work, I think the are working on adding this. (I hope they are). But for now you can process your audio with a different app, or if your audio is the same for the same staging of the video then you can make custom filters that act as noise gates and cut out certain frequencies like from you central AC, or computer fan noise.
Once you make one that works for that enviomrnet you recorded the video, you can save it for use later. It’s not the easiest, but it get the job done if you don’t want to use another app.
I’ve attached an examplesmfor lne of my filters. I think the main thing I find my self adjusting is the expansion threshold and ratio.

It solid be nice if Luma had more information on the audio, like what the lowest decibel and highest decibel level is in the audio clip so I could adjust these faster. So you slide back an forth until you find about what the audio level is. I use the expansion ratio to drop the noise floor off, and the expansion threshold for what minim level my voice is to alllow the audio back.

The high pass removed my central air hum blowing when it comes on. The low pass clears up the high pitch noise from my Network Stoage Fan.
I hope this helps a little. If you google some of these filters you will find some good videos on YouTube that can help also.

Hey. Thanks for the reply. My topic was referring to a video denoiser, rather than sound. However this info is very helpful so I do appreciate it.
