In Camtasia Studio you can actually export the audio separately that's on your timeline into either a .wav or .mp3 file format. To do this, expand the File Menu and choose Produce Special > Export audio as. The audio can be on any Audio Track on the timeline...and doesn't have to be unlinked from the Video 1 Track.

Here's an image that should help.

Ryan. That is great information. I think to add to this I would say that works great if you recorded the video using Camtasia Recorder but, when I just tried recording voice narration using PowerPoint 2010 and saving the video then importing it into Camtasia Studio 7 and exporting the audio it did not work correctly. I am using the PC Version so can you confirm if this is correct or not? Thanks Fred.

Fred. I just tested this with PowerPoint 2010 and it seemed to work fine for me. I recorded a PowerPoint presentation with the Addin Recorder...brought it into Camtasia Studio...and exported the audio (using the process described above) into both wav and mp3 successfully. If you are still experiencing issues, you may want to open a ticket with our support team to help figure out the cause. http://techsmith.custhelp.com/app/ask Thanks, Ryan

Yes,
 the image below shows saving to a .WAV file but you can select MP3 from the same drop down menu as well.

Yes you can, David. It's found under the Share menu...and choose 'Audio for Captioning'.

Hope this helps.

sitecentre101, Once you export your video you can share it in a number of ways. I think you might just want to manually upload it though. Here's a tip too: if you're using Screencast.com, you may wish to enable the download link. This will give your listeners the opportunity to stream it online as well as download it to a device of their choosing. To enable downloading, edit your content details and check this box as shown here: http://screencast.com/t/hrhbafY1Ohh

To edit content details, first make sure you are signed into Screencast.com. Next, click the piece of content. Under the content, click Edit Details. (If you don't see this option you will need to first click Show Details.)

As to the question about working with Camtasia for Mac and iMovie together, would you mind putting that in a new post? I think a lot of people would be interested in this information, and unfortunately I have no way to fork or split this topic. I'm worried the information would become lost in this thread.

Thanks for posting!

But when you bring the audio file back in to the project, the volume is like 20% lower! This is true weather I edit the file in Audition or even if I simply Export Audio Only, then immediately bring that same file back in. It is visibly lower (smaller waveforms) and audibly lower.

Hey Doland Ruiz,

What version of Camtasia are you using? I've been doing some testing this morning.
I'm not getting that in version 2018, "Lower volume" However...............

For me, the exported file is 2 frames out of sync with the original "Every Time". It has to be shifted 2 frames to the right for the wave forms to line up with the original. The audio that should be heard at the start of the recording, is at the start of the exported file. And becomes displaced when you line up the majority of the file. The audio "Overall" comes into sync around 1/3 of a second in.    

Plus, there's a lot of inconsistency between the 2 wav forms. Drops in volume spikes is where it's visible. The exported file has a lot of them filled in or reduced.Some have been added. It's hard to know how much damage is being done to the original quality. The wave form isn't going to tell you that information and once you've exported it the damage is already done.
I did my testing using  .trec recordings. Using the latest version of Camtasia 2018.

The original audio file is on the bottom.The exported and imported .wav file is on top. I've highlighted some of the more glaring inconsistencys.



I took the same recording and placed it in Camtasia 9. I ran into none of these problems.

The audio stays in sync and the waveform matches perfectly. “At least, I can’t see any anomalies”

Clearly, this up as a 2018 bug.

Regards,Joe

I just purchased 2018. I had used 8 at work. How can I save audio file in MP3 in 2018 like I could in 8? It now comes through as MPEG4.

.wav is a lossless format. It doesn't lose quality when exported. So when you produce a video with it, it reproduces sound better than mp3's.

The mp3 format compress's audio files down to a very small size.They sound great,mp3's were designed for listening to.

But there's nothing left for for a Video Editing/Slide Editing/, etc. program to work with.
So, when you go to produce your finished product. The mp3 is compressed again. That audio track has no options, the quality takes a hit. 

Generally, with a voice track you won't notice the degradation much. Do this to music and it becomes obvious fast.

As a general rule. Don't use mp3's unless you have no other options.

.WAV  files are roughly 10 times larger than mp3. And completely unnecessary for listening purposes.
m4a is just the new mp3.But it isn't wav.

My PowerPoint rejected the file, "format not recognized". I'll try again and/or try wav versus mpeg4. Thanks again Dubie!

m4a only works in Powerpoint 2013 and newer.

I don't know what version of Powerpoint you are using so if it's earlier than 2013 that could be the problem using a m4a file.

I pretty much always use .wav files and have no problems.
I'm using Powerpoint 2016 (not Office 365 Powerpoint )

Quality audio is important to me so as Joe pointed out .wav files though larger in size results in a better quality audio all said and done.

Plus .wav works best in Camtasia so I try to keep things consistent in a project between PPT and Camtasia when possible.

:)
