High pitched,noise and helium like voice

[WalkRacing]

Audacity 2.0.5
Windows 7 x64
File recorded via TeamSpeak v3
File recorded with SteelSeries Siberia V2 via USB
File full lenght 16min

First of all i am very very new/novice/newb to this to get this out of the way.Secondly i used TeamSpeak before as it's easier for me to record there interviews/friendly chat with other team members and so on,i hate skype.Thirdly it's first time i used the Siberia headseat in the past i had sennheiser (don't remember model,but it was the first with drop-down mic)and with the Sennheiser didn't had this problem.
What i want to know if it can be fixed or i have to record again?and if yes how?
As you can listen it's very very high pitched with a awfull background humming/noise and it sounds like i am on helium(maybe speed) and really don't know why, any help in this matter will be greattly apreciated

thank you

The Helium effect can be reversed by dropping the pitch by about 50%, but in your case the result is not broadcast-quality because on your original audio every-other 1/10th of a second is missing ...

''Helium'' TEST, before-after , ( discard left track , then drop pitch by 50% ), last-take 2 copies interleaved.flac

the 1st "after" is very-gargley because every other 1/10th of a second has been chopped-out on the original audio. The missing bits can be patched(ish) by interleaving two copies of the gargley-version, 1/10th of a second out-of-sync.

Will this tool work with current Audacity version?Because I want to make voice of Porky the Pig and Tweety the Canary from Looney Tunes.

You'll need to channel Mel Blanc or hire Bob Bergen ... https://www.youtube.com/watch?v=s3R0Riqm-H4

Channel Mel Blanc kind of like spiritual connection in Phoenix Wright series?
