Help with audio/video syncing in Adobe Premiere Pro CC

[Klaustronix]

So I record my microphone with Audacity, and record my gameplay, game audio, and microphone with Nvidia Shadowplay as well. I record my microphone in Shadowplay as well for better syncing, but I need some help in this. So after I adjust the microphone audio with my Shadowplay microphone audio, using wavelengths, and let's say I need to cut a part of the audio/video to edit it, the sync messes up, Why is that? And is there a way to fix it?

This is probably not explained very well, but I don't know how to explain any better on this. Could someone please help?

1) Import external audio and video in to your project.
2) Place both the video (with audio) and external audio in a sequence.
3 Highlight both video and audio clips, right click and select Synchronize Clips.

I tried to do that before, but my audio from Audacity tends to be longer than the Shadowplay recorded file (since I start recording before I go in-game to start recording), so I can't use the sync option.

I usually record in "Voice Recorder" on Windows 10 and import it to Premiere to make adjustments to my audio.
