Please fix the "Change Clip Speed" option also changing pitch. It's not that hard. (Camtasia 9)

Mac has a way to independently change pitch AND clip-speed. This forces anything faster or slower to become a different tune. There's a thread where somebody has the same problem SIX YEARS AGO and you solve it for Mac. Why is this still a thing? I want to make the clip longer, not turn everybody into Darth Vader. If I want to make a funny reference quickly, I don't want the sped up clip to stab my viewers' ears with chipmunk noises.

I honestly do not care about the whole "well the audio quality gets worse because the machine has to "fill in the blanks" and it sounds like garbage" I KNOW HOW THAT WORKS.

Say there's a glitch in a Gaming video. It creates an absurd moment which is so out of the ordinary it incites a laugh. To highlight this, I might slow the clip down (as it may have been less than a second), and zoom in on that area. The bizarre way the audio distorts, combined with the full zoomed in view and natural humor can make a viewer laugh out loud.

While lowering the pitch can also be funny, many time it is unnecessary and is pretty much just overkill.

I'm also making a video where all the national anthems to the tune of "God bless the Queen" are overlayed on top of "Sweet Land of Liberty". I don't want it to sound like a hot mess.

I'll wait for the independent pitch changing to be ported over from Mac.

But this stupid "Changing speed changes the Pitch" has got to go.

Please do it: I've found an easy to implement formula on Internet:
Let X be new video playback speed, be it 0.68x (68%) or 2.15x (215%).
Semitone shift = 12 * log(1 / X) / log(2)
For 0.68x => 12 * log(1 / 0.68) / log(2) = +6.68
For 2.15x => 12 * log(1 / 2.15) / log(2) = -13.25

completely agree. This feature is making me think of switching to different software, as it takes quite a lot of fiddling to export to Audacity and reimport to do this for every single video.

I have two presentation clips from the same speaker that I'm trying to combine in one video.  Unfortunately, in one he talks more quickly than in the other.  I tried speeding up the other one to match his cadence, but now he sounds like half-man, half-chipmunk.

I'm able to change clip speed without changing pitch on the FREE Audacity program.  I paid good money for Camtasia, so I would hope the audio capabilities would be at least as good as free software...  ESPECIALLY if you already solved this for Mac YEARS ago.

Do we know if TechSmith solved it for Mac, or do we know if Apple solved it for Mac, and TechSmith just used that?

We just know it needs to be solved.  ;-)
