WiFi router / dongle, LED lightstrip, TV, other) or if it is an audio USB dongle, of dubious built quality, it might be picking up interference from the data exchange going on on the bus. This first step teaches Audacity about the noise you want to remove by. Although the sound can come from a persons voice or vocals, some microphones deliver a high-pitched haystack at the high end of the recording spectrum.

It sounds like interference and it is likely that it is picked up as a square wave. It will be bonus for me if someone can tell why this high pitch noise occur in audio? You can then take that profile and apply it to other points in the recording to reduce its impact. Audacity will use this to extract the noise spectrum and then create a filter that cancels it. To apply that filter, select a part of the recording that is representative of the noise profile you are dealing with. The latter option is better when the interference is over a useful part of the recording. Audacity maxes out at 20 kHz if you can hear that. High frequency sound causes two types of health effects: on the one hand objective health effects. Increase the frequency 1 kHz at a time until the subject can no longer hear the high-pitched sound.

I record at about 0.75 recording volume, with my USB interface at about 60 gain. I've got my mic in a closet with a pop screen, surrounded by clothes, with a blanket taped up above.
