After upgrading from 8.4.0 to 8.4.1, I now get a horrible metallic effect on my voice that sounds like it was recorded in a bathroom. Is anyone else experiencing this? Any recommendations on how to fix this?

for me, this is a known issue with 8.4.1 [a in-a-barrel sound]

a workaround ...

do not use CS noise removal

export the audio as a wav file, import into [free] Audacity, use Audacity's noise removal function [effects menu], then export that as a new wav; use that wav in the project [either separate original audio/video and delete the original or disable that audio track; then, no issue with sound

I just updated and noticed this effect as well. Very irritating.

my workaround described above works very well and only requires a little extra effort

Thanks for the tip. I gave it a try and it does sound better this way. But that doesn't reduce my irritation with Camtasia, which has been high ever since upgrading to v8. I need to look at alternative programs.

It was my understanding the focus of version 8.4.1 was going to fix the noise removal issue of 8.4 .  I uninstalled 8.4 and reinstalled the latest version of 8.3 .

Same here. Didn't realize others had the same issues. But I just re-installed 8.3. I'm going to have to go back to running my recorded footage through Premiere Pro, and that's more time/work simply because Camtasia took a MAJOR step back...not forward...in Noise Removal.

I record my tutorials in a home office, not a sound booth. So, noise removal is a pretty critical component.

Sorry, I just posted a topic about the same issue, but used different words to describe the issue, thus I didn't notice this topic was discussing the same thing. Please see my topic as well... I'm referring to the problem. I just removed noise removal, per kayakman's suggestion, and that horrible sound is gone. Techsmith, please fix the noise removal problem.

This reply was created from a merged topic originally titled
Upgrade from 8.4.0 to 8.4.1 automatically added reverb to my audio voiceover..


I updated from 8.4.0 to 8.4.1 (build 1745) and now my previously recorded mono voiceover audio track (spoken words, one track, one voice, no music), which originally had near-zero ambient sound (reverb sound of voice in room), now sounds like someone added reverb to it, so that the reverb of the voice in the room is exaggerated. I'm a professionally trained audio engineer, so I know how to make extremely dry recordings with as minimal room sound as possible, and that's what I had in 8.4.0. Since there are no "reverb" audio options in Camtasia, I'm assuming the application is actually (somehow) playing back the audio track simultaneously in duplicate, where one is a few milliseconds behind the other, which would create an artificial impression of reverb. I'm using an HP Elitebook 8560p with Windows 7, Service Pack 1, 8GB RAM, 64-bit OS, Intel Core i7-2620M CPU @ 2.70 GHz X2. If anyone can resolve this I'd greatly appreciate it.

We have an open bug on this issue, and it should be resolved in the next release.  In the meantime, the workarounds are to revert to 8.4.0, or to export the audio and sweeten it in a 3rd party tool, such as Audacity, as suggested by kayakman above.

I'm sorry for the trouble this bug has caused.  We are working to get it fixed.

Dave, this problem has really sunk my confidence in CS, and the past several tutorials I've recorded and edited have introduced a ton of crashes (noticed them many times before, but the longer the tutorial and more edits/cuts the more frequent the crashes).

If CS doesn't improve dramatically in these two areas (stability and noise removal), I'm not even going to consider making the paid upgrade when v9 rolls around. I rely on these tools as part of my work...and this software has made it considerably harder to do that very work.

I agree with you 100%. I have recently posted with similar concerns.

Now Camtasia 9 is in the works and probably getting the lions share of the engineers attention.

@Joe, @dnashj33:  We did find and fix a memory leak for the next release that we believe is causing some of the instability, especially with projects that have a lot of edits.  We also isolated the root cause of the noise reduction issue.  These fixes will be released in a maintenance release, free to all 8.x users, as soon as it passes our final testing.  Once we become aware of issues like this, they are worked on immediately, and we put a release plan into place to get those fixes out.  We will continue to fix bugs on 8.x, as needed, while we work toward our next major release.  I'm sorry for the inconvenience these issues have caused you.

It's odd that I opened a ticket about this issue of poor audio quality and the support technician assigned to me said that Camtasia is unaware of this issue.

Tech support has acknowledged the issue to me, so I would request a different technician, or send him a link to this forum post, where he can catch up what other employees know about the issue.

Just updated to 8.4.2. From what I can tell, it has resolved all my issues. Am I imagining this? If not, great work Techsmith. Big relief. Anyone else?

appillar What is your Build Number (i.e. 1767)? I got an early copy before testing was complete.

1768. FYI, just noticed, when employing noise reduction on a track of narration, after sounding fine for the first minute, a sort of "phasing" sound began to appear around minute 2. I turned off the applied noise reduction and it was gone. But with 8.4.2 something is indeed different with the noise reduction in general, because the problem I previously heard with 8.4.1 didn't sound like what I just heard with 8.4.2 (1768).

Thanks for that. My 8.4.2 shows build 1767 so something changed. I will download the latest and install on top. I appreciate your feedback. I used Noise reduction all the time to eliminate HISS from my analog mic (really noticable on my iPad & iPhone).  My last few videos that I produced (8.4.x) I had to not use Noise Reduction because of the hollow sound. I can't stand my voice to begin with (I was not gifted with a Radio Announcer's 'Voice of Authority'), so to screw it up even more was disheartening.  Tech Support did provide me a beta version of 8.4.2 early on because of all the crashing issues I was experiencing during editing, and long renders.

I didn't get the opportunity to really exercise it because when I rendered a 720x480 MOV, the resulting MOV had black Bars on the sides (I'm sure I had messed up 480p size parameters) but rendering took hours so I used NERO 12 with CUDA Core rendering to cut transcoding to 1 hour (so I haven't messed with it much).

I will try the Noise Reduction, 8.3 had it right, but I didn't want to lose my Production Presets.

Thanks appillar for responding quickly.  My tools have been giving me fits, and I have been losing money (billable Hours) with Crashes & poor hiss reduction.  My frustration stems from poor productivity.

I'm using 8.4.3 and noise removal doesn't do anything...
