Question about audio files

General

If I’m reading the manual right, there’s a menu setting in movie mode for recording volume. If that wasn’t at maximum, it might be a factor. Wind is often a source of noise. That can be lessened with angle or blocking the wind with a hand or covering the mic with porous/light fabric in a pinch. Steady white noise like this, though, sounds to me like just the baseline of the equipment. Raising the recording volume might also increase the volume of the noise proportionally. If the volume adjustment doesn’t help, there may be nothing more that can be done to get better audio from that camera. It looks like like audio can only be recorded with video or as a memo. The video has quality settings, but imagery uses the bulk of the space, so the compression level of the audio may be the same with all of them. I didn’t see setting for the memo. I don’t think it can record uncompressed audio. It doesn’t look like it can connect to an external mic. With most smartphones, though, you can record uncompressed or connect external mics.
