Remove "noise" from Audio File

Hi Everyone can anyone help me please?

I was doing an audio recording and using a ZoomH4n Audio Recorder to make this work.

When I got home and ran the file through Audacity and I heard two “clicks” like someone opening a door and I want to know how to remove this?
Via the Spectogram.

Many Thanks!

Spectra editing : like photoshop, but it changes the audio.
