I am very new at FCP. I recently recorded a small project and I used a shotgun mic. I am hearing alot of i guess atmosphere noise in the background. It's not noise coming from any object or person it just sounds like i guess a hiss or just air? Not sure how to describe it. But anyway I wanna know how I can reduce the atmosphere noise. I remember in premiere there was an easy way. However I can't seem to find out how in FCP. Any help would be amazing!!!Thank You so much.
Please suggest a way to get rid of background air noise

If the wind doesn't have s specific frequency that you can isolate and EQ out, then you can try a noise gate filter, which opens when there is loud noise (like dialog) but quickly closes when that loud noise stops (thereby shutting down the sound completely when there is no dialog). The thresholds for 'open' and 'closed' are adjustable. The theory is that when it is open and there is dialog, the dialog will mask the underlying wind noise. It rarely works the way it is supposed to, but when it does, it can save your track. You'll still have to slug the holes (where there is no sound) with room tone (or, in this case, wind "tone") mixed way back.

The hiss your hearing is probably noise created due to the low threshold on your recorder, or poor quality preamp. This means in laymen terms the recording device was told to record many unneeded frequencies of sound over a certain level of amplification and this level was quite low.
The thing to do now is to identify the range of frequencies that contain most of the sound you want to get rid of. This is normally left for the sound engineers or mixers.
But on smaller (cheaper) projects when I edit in I normally open the effects window. Open the drop down menu of the sound effects and select a 3 way equalizer drag and drop it on to the audio clip. There are specific hum and hiss removers that work well sometimes could try them as well. Double click the clip and open the effects tab open the equalizer then play the clip. Listen to the noise, is it a high pitched hiss or a heavy hum? For a high pitched hiss you would need to find the relevant higher frequencies and adjust their gain level, low hum the lower frequencies, you can also adjust the range of frequencies around the specified one. Since you have three level controls you can adjust three different ranges of frequencies.
Best way to do this is with a graphic representation then you can really wave through the graph until you find the sweet spots.
As the clip plays through wait for a section in which there is the least amount of sound recorded and the hiss is most obvious. Adjust the frequencies and their levels until the hiss is at its least noticeable level. Then apply the same effect to all clips with a similar noise problem.
