Noises when editing audio
Hey.
This is what I do:
- I record audio in Sonar (using a mic to record sound coming from an guitar amplifier)
- I cut out a part in the recorded audio and re-record the part I cut out.
- When I've done this, where I cut, there is a little noise. Almost like a little clip.
I wonder, what is this clip-noise?

This is because you've cut into a point where there's an audio signal present.
You could try cutting at a zero crossing point - ymmv with this though, it's not 100% foolproof
Instead of cutting a part out, you could try simply setting appropriate punch points and punch in
You could also try recording the flubbed bit onto a new track and use track automation to fade the old data out & back in using tightly defined curves
You could use a 3rd party wave editor to home in on the clicks and edit them out
You could use clip automation on what you've already recorded - again using nearly vertical - but not quite vertical! fades

3rd party wave editor? Can you remove the "clips"whitout having to re-record the audio with this?

Yes, you can even do it SONAR. Zoom in and cut them out of the track. You can either delete the hole made by the edit or fill it in with a small piece of the adjacent clip. Some prefer to use dedicated editors for this function. Some editors have automated tools to assist in the process.

Try putting a short fade in or out on each end of the clip that you cut.

Crossfades have been SOP since we were making edits with razor blades. Back then, you always cut tape at an angle so that you wouldn't hear the splice. Digital audio is no different, just much easier.
Whenever you split a clip, put a short fade at the split point. In most cases the fade can be very short, often less than a millisecond. Sometimes you'll need longer fades, especially if there's a lot of noise in the track (e.g. a vocal recorded live with the band playing).
 All else is in doubt, so this is the truth I cling to. My Stuff

I do audio edits a lot. I set the snap to grid to whatever resolution I want..... I split the clip in 2 places... before and after the event to be replaced..... I highlight that clip and set my punch in out points automatically and then set the now marker before the split and hit record.
The punch in is totally silent... meaning that there are no edit clicks in or out.
Those clicks you hear come from a non-zero crossing edit split.....or from a non perfect drag and drop. There is an option to have all splits occur on zero crossing points and I believe it is set that way by default.
Using a third party editor or trying to make non snap to grid edits are very often problematic. It is virtually impossible to get the 2 clips to line up properly so that the click is not audible.
Try the method I suggest in the first paragraph. For me, that is a flawless way to fix an error in an audio track.
