screeching noise front left

[Kroner02]

Recently i started hearing a faint screeching noise. Sounds like it is coming from the front left wheel area. I did a quick inspection but cant find anything out of the ordinary. I have attached video with the sound, it is faint but if you listen closely you can hear it come and go. The noise varies with how loud it is and sometimes you cant hear anything. Any ideas regarding this noise would be greatly appreciated.
