Repairing a sound warp?

Hello everyone,
I am in the process of transferring my recordings onto new formats. Everything is going well, and I love Audacity - I more or less undertand everything. However, I am struggling with one small detail and cannot get a solution myself. I have a 3 minute recording and at two or three times during playback the original recording has a slur (If that's the right word - or maybe a warp) almost lilke a tape drag. The recording seems to have slowed down for a split second, there's also a couple of noises that Ican't seem to shift (Clicking) I have tried noise reduction and zooming in to use repair, but there appears to be no fault with the recording -
Any help, much appreciated

We do have this wiki on improving quality and it mentions hardware problems. Your computer may not be able to keep up with the work. Slower computers which seem just fine for Spreadsheets and Photoshop will fall face-forward when you try to do live audio or video production. Live audio doesn't wait for the computer to catch up. If a musical note arrives when the computer is still thinking about the last one, there is going to be damage and odd speed changes could be one of those problems.

Make sure Audacity is the only thing running and stop doing email at the same time as the production. Defrag and error check your hard drive and make sure you have plenty of room -- 10% to 20% free space. You may need to disconnect your network and disable your virus software.

And lastly, you may need to change the Audacity program.


Audacity 1.2 is very old and no longer supported,
patched, corrected, or updated. Audacity 1.2 can
be unstable on newer computers.

Download and install the latest Audacity 1.3 from here...

http://audacityteam.org/download/

You can install both audacity 1.2 and Audacity 1.3 on
the same computer, but only use one at a time.

Audacity 1.2 will not open projects made on Audacity 1.3.

If you use MP3 or some of the more modern audio
compression formats, get Lame and FFMpeg software
from the same web site. Do not use older software
or software from other web sites, even though they
may have the same names.
