Audio Buzz when Screen Recording

Hi everyone. I reviewed many previous posts about how to address this issue but it seems like I'm still having difficulty. I'm trying to create/edit a Camtasia file from an existing Power Point that was recorded with voice overs. When I do so, the audio has a distinct buzz which makes it difficult to listen to, in particular because the topic is about relaxation and mindfulness and the buzz is a distraction. I've tried many of the steps recommended in previous posts: disabling audio enhancements, updating drivers, turning off auto-normalize sound in the Project Settings, unplugging the computer from the power outlet, muting additional sound inputs...and it's a little better but still not where it needs to be. I'm stuck and unsure of where to go from here. Since we are all operating remotely, I'm not able to record the video live on my system, and short of having the creator re-record it on her end, I'm wondering if there are other solutions I can try? 

I'm running Windows 10 on a Dell with a 7th gen i5 processor. 64-bit Camtasia 2019, version 2019.0.10 (build 17662).

Thank you in advance!

Can you hear the buzz during the time words are spoken or just between the words.

Hi there. The buzz is only with the spoken words.

That's hard to git rid of.  Is there any piece o software you can play it in where the buzz doesn't exist?

Unfortunately, no. Once it was recorded the buzz seems to be part of the audio track.

Have you tried exporting the audio from your project and re-coding it?

Camtasia works best with 44,100 HZ -16bit .wav files.



With Audacity  (free) it's easy to do.

Export the audio from Camtasia and then drag and drop it into Audacity

Set Audacity for 44,100 Hz and 16 Bit.

Export the audio as a .wav and bring it back into Camtasia

I'd also be curious to know if the original mindfulness powerpoint recording (I'm assuming it's an MP4 with video/audio) was done in Camtasia or elsewhere. 

I also wonder if Camtasia's noise removal could isolate/silence that frequency? Unless I missed something, I didn't see that as a step the OP took in remediating the issue.

Hi Dubie. I haven't tried that but can certainly give it a shot.

Paulwilliamengle, the file that was sent over was the original .ppt file, recorded in Power Point and not in Camtasia. They don't have access to Camtasia and since they've already recorded it I'm trying to work with the existing file before having to have them redo anything. I tried some of the noise removal options but it seems to be occurring in the Screen Recording processing.

Morning, all. 

I tried importing the audio into Audacity and fiddled with it as much as I knew how, but because the track itself has the buzz I wasn't able to get rid of it to my satisfaction. I may try to re-record it into Camtasia and look at any audio processing options BEFORE I record, as opposed to after.

How did you make out with this?  I think I can get the buzz out.
