How do I remove background noise with the Camtasia 9? It was easy to do with the camtasia 8 but now when I attempt to remove the noise, I end up with audio that sounds like I am under water.

In my instance, I have a .wma file, about 2mb in size (1 hour recording).  Trying to perform noise removal takes for ever, and producing the file or exporting the audio just stops at 39%.  I've got fed up of waiting and am finding alternative products.

odd. Well, if you're looking elsewhere you might not be interested, but we'd certainly like to have a look at that file, if you wanted to open a ticket with Support.

I'm having the same issue. It worked great in the prior version and now I just get so much noise, it doesn't seem to work no matter what I do.

Any idea when it's going to be fixed? I had the same issue yesterday.

They are NOT going to fix it. It's been decided that it's a glitch and they suggest we use Audacity which is a complex PITA. It's like they took 2 steps backwards and 1 step forward. Looks like I will stick with the older version!

> when I attempt to remove the noise, I end up with audio that sounds like I am under water.

I observe the same (Camtasia 3 for Mac), and I noticed that this does *not* happen on very long audio clips (e.g., one minute of continuous recording). Short clips of a few seconds length tend to have the "underwater effect" in various forms.

I'd guess that if it was possible to stitch all audio clips together to build one large final audio clip, Camtasia's noise reduction would work quite well. 

Unfortunately, combining adjacent audio clips into one is not possible.

You could combine clips together to make it as one by just publishing them all as an mp4 and then importing that into a new project.  This way the audio wouldn't be separate anymore...just one big file.

interesting that Techsmith isn't responding to this thread...So what I can assume here is that V8 is better than V9?

my suggestion ... do your screencasting with CS9; but use free Audacity for noise removal

since this is a user-to-user forum, TechSmith will often not chime in; for a specific issue, best to contact free tech support

I constantly make short screen casts for contractors and clients and am actualy even thinking of finding a simpler straight to youtube way or maybe just straight to slack recordings if possible. But, thanks! will check it out as I do make things that are more important.

The audio in the tutorial also sounds underwater.....it's inexcusable that TechSmith doesn't fix the Cam9 issue.....it's not very customer-focused that no one from TechSmith comes here to help or comment.....

Since the Cam 9 came out, I have learned to just use it to fix the color, then use the cam 8 to edit and produce... much easier than trying to use Audacity!

I've done the same.   It's a great feature in 9 to be able to edit the colour/bright/contrast of a video, but there's so much unnecessary change and extra clicking in 9 that I'm finding it frustrating to use.   In terms of noise removal, I've found 8 better but still limited.

I noticed there is no option to capture the noise profile.  In version 8, we could capture the room tone, or noise profile and then did the noise removal.  It worked wonderfully.  In version 9, all I see is the option to remove noise.  Without a noise print, any piece of software ill do a crappy job of removing noise.

How did you capture a noise profile in Camtasia 8 ?

I selected a portion of a clip, usually 2 seconds of just the room tone I recorded, then there was an option to click "manual noise training on selection" button.  It removed noise well after that little step.

Ah, I never knew that is what that button did.   Think I'm achieving the same results though by just selecting the audio clip, ticking Enable Noise Removal and then tinkering with the sensitivity until I find a happy medium between removed background noise without making the voice sound weird.

BIG DENT IN CAMTASIA. I like that. I wish it was not so.
There seems to be much less control of audio in V 9  vs  V 8.

As a newbie, I 'm a bit flummoxed by this issue.  My problem with Camtasia sound hasn't been that it is ALWAYS bad, but that I can't figure out why SOMETIMES it's bad.  When my Camtasia sound is good, I really like the sound it produces, but I'm never sure about what I'm going to get.

I used Kayakman's tutorial to do NR in Audacity, and it works pretty well, the sound is acceptable.  But I don't think the sound I got was as good as the sound I got from Camtasia when it was behaving itself.  Maybe practice would smooth things out, I just don't know.  

Learning how to plan and make videos is a pretty big chore all by itself, I really would prefer to not take on Audacity at this point  If Techsmith would help us with enough info on how to get consistent sound quality,  that would help a lot.

That's suggests that you have a technical problem.I doubt that the problem is related directly to Camtasia.But that's just a shot in the dark on my part.

It may be your microphone.A driver or a hardware issue.

I would run this by tech support and see if they can help you resolve this.

Is the sound quality that you observe perhaps related to the length of the audio clip? If I remember correctly, I mostly got bad quality when the clip was short (like, 10-30 seconds).

I have moved to Audacity for audio post processing. The NR algorithm is awesome. Select a few seconds of silence, let Audacity detect the noise, then select the whole track and apply the denoising. Works like a charm.

If you can't install audacity, you can just add the noise removal, adjust the sensitivity on a part of the clip in which you are actually talking, lastly mute the audio that is just background noise. I'm pretty sure this is what getting the noise profile does anyway. Hope this helps.

Start by uploading the audio track into the time line. Then select and highlight the region that contains the noise. Now click on Edit and select Audio Enhancements. Under Background noise removal, users are able to select to automatically or manually remove the noise. Once selected, simply click on the Remove Noise button. Users also have the option to adjust the sensitivity.  Audacity   Find My iPhone  Origin
