What is the format of this audio track and how was it recorded? Are you doing a straight cut or also trying to engineer some fades after the fact? I just compiled a promo clip from several separate clips made previously and at least a dozen trims to get it down to three minutes. I never have noises (artifacts) like that. While the bulk of my audio work is produced outside of CS8 and then imported to the clip bin, the cuts I referred to above were made on the CS8 timeline.
What version of Camtasia are you running now???
The newest version is 8.6.0
I cannot even reproduce the problem shown in your video because Camtasia quit recording to .camrec files in May of 2014. Even back then Camtasia was still loaded with bugs. I wouldn't run a version that old for any reason. Unless you're still running Windows XP?
If you are running Camtasia 8.6.0 maybe you could upload a current video demonstrating the problem?
Or better yet contact Tech Support and let them sort this out for you.

my original captures often sound noisy like yours [I use a AudioTechniques external USB mic], and Camtasia's Noise Reduction function does not work that well for me
however, the Audacity's NR works great for me
I believe the problem is related to a microphone setting in
some way. I understand that you are capturing audio to a .trec file.
I played around a bit and recorded my webcam. The audio was set to the default setting of 32Khz with the Logitech Webcam Software. I recorded the webcam directly through Camtasia and I was able to reproduce the audio popping you have encountered.
I switched the setting to 48Khz and ran another test. The popping was alleviated at that frequency.
This may not make any sense. However, Logic doesn't necessarily apply when you are trying to workaround a software bug. If logic did apply to this issue then it probably would have been resolved by TechSmith long ago.
I even played around and imported a 24 bit audio file at 96,000 Hz directly into the editor. The popping was more pronounced.
At 16 bits and 96,000 Hz there was no popping at all.
I can only surmise this from my tests.
It's probably an issue you can resolve yourself. Provided you can stumble across the right setting for your microphone through experimentation.
I don't own a Yeti mic and so I have no idea what your options might be.
It may even be related to a Windows driver or something along that line.
Unless someone in this forum has actually encountered the same issue and resolved it. The odds that you will find a solution in this forum are probably not that great.
I'd run it by Tech support and see what they have to say. I've seen several problems posted associated with Yeti microphones and Camtasia. There seems to be some inherent compatibility issues involved.
Good Luck John,
If you resolve this there are other Yeti users that can benefit from your findings. Post back with any updates please.
Are there any downsides to recording to avi as oppossed to trec? I do not use mouse effects.
Does the issue happen while recording webcam, or microphone only?
When recording to .trec, Camtasia always converts the microphone samples to 44.1 KHz. You can try to change the microphone's input sample rate and depth using Windows Sound control panel (right-click on the speaker icon in the system tray):
We also released version 9.0.0, will you please see if the issue is present in that version as well? https://www.techsmith.com/camtasia.html
If so, please consider opening a support ticket, and we can take a look at your specific setup, hardware, and files to debug the issue more thoroughly. https://support.techsmith.com/hc/en-us
Thanks and regards,
When I play them in any player before I import them into camtasia, they play cleanly, with no audio anomalies. After I import them into Camtasia, there are very noticeable pops throughout the entire track. They are there before doing any editing whatsover - I simply import the file, select play and they are there. When I first noticed it, the problem seemed to be inermittent. Now, it happens with every single video I import. I am using version 8.6.0 I have enjoyed using this software, and have had great results with it for some time. But now, unfortunately with audio anomalies being added to every video I try to work with, it's become useless to me. I have spent time searching for the solution online, but don't see this specific issue addressed anywhere. Please help!
I have done two cuts inside the sinewave. Both at points where no zero crossings are.
The Pic is of the first pop of the waveform.
Lost. What can I do - i'm not a sound engineer and do not have the time to export, split sound, bring it back in, etc., as I've seen in other posts.
