Hissing noise in background of camera audio

[Tristan12]

So far I have been using my phone with a $30 lav mic for my youtube channel, and I’m happy with the audio, but now I want to upgrade to a proper camera for better image quality. I bought a Canon EOS M50 mark 2 and also a new external mic for it (rode videomic go), but the problem I am having is that there is a hissing noise, like white noise, in the background of the audio. This happens with or without an external mic. I have messed around with the settings, researched solutions, called Canon and even returned the camera and bought a new one in case it was a dud but I still get the same hissing noise. The audio from my phone with a $30 lav mic sounds better than this $1000 camera with a $120 mic.

Yes I could just record my audio externally, but i'd rather not have to if I didn't need to. It just surprises me that this camera is so popular among YouTubers, yet it has these issues with the audio. I'm pretty sure a lot of cheaper cameras have this actually.

I want to know if anyone knows of any solutions for this, if there is a camera under $1000 that wouldn't have audio issues like this. I'm not sure if I would just need a more expensive camera for better audio quality if I’m going to be recording audio into the camera, and that with a cheaper camera like this maybe I would just have to record my audio externally? I'm interested to hear from other people who have experience with cameras to see what you think.

When I watch Leo's videos, (and a lot of other people's videos) his audio is great, and there is no white noise in the background, but maybe he has a more expensive camera or records audio externally or something (?)

This seems to be someone with the exact problem as you.

 

Also you can run your recorded audio through an audio denoise program online. It will remove the hissing noise in the background. Problem is the one online has a limit on how big the files can be. You might have to find some alternative. Also since this is free, it might reduce your sound quality. Instead you can tinker around in audacity.

I mean at this point just record your audio externally if you can't fix it. My best guess is that it's a problem with the camera settings not matching up with how the video encodes over to your pc/laptop or something.

@Swarnim Thank you

@Tristan12 I can’t imagine it’s a problem with the camera. I have a cheaper Canon model and it gives me no issues as far as audio.

Probably it is your mic or the way you are recording. Some microphones pick up only noise from in front of them while others pick up noise in more of a 360 degree way. If you have a 360 mic that is very sensitive then you could be picking up minor sounds that you only really hear once recorded.

@aurum The noise isn't that loud, and it would probably be fine if I recorded with it, so I’m guessing its just how that camera is, but I want my audio to be perfect especially considering that the audio from my phone with a lav mic is better and doesn't have that noise at all.

The mic I have is directional, and i've tried it with and without the mic and there is still the same problem.
