When I go to play back a recording, the audio plays in fast-forward mode. How do I correct it to normal speed?

Ok, I've tagged this post as Camtasia for Mac in the lower right. This helps it get seen by the C:Mac team.

I found this article on our support site that sounds like it might be related: http://techsmith.custhelp.com/app/ans...

If that doesn't help, please open a support ticket at http://support.techsmith.com and someone from our TechSupport staff will follow up with you by email to help.

Hope this helps.

Hi There;

I have this problem as well, and I use a Windows 7 PC (a relatively new box with ample CPU and RAM).

Problem is, it's intermittent. Sometimes it happens twice in a row, other times just once. I reboot and the problem fixes itself. Is there a setting I need to make to stop this activity?

Bill,

The Camtasia Studio product on Windows does have a clip speed feature. Perhaps that has been applied? Here's a tutorial on clip speed: http://www.techsmith.com/tutorial-cam...

If that's not it, then it's not something I've seen, and it's going to take some one-on-one troubleshooting to get to the root of it. The best way for us to help you is for you to get in touch with our TechSupport staff by submitting a question at http://support.techsmith.com

Hope this helps.

I am having this same issue in 8.4.4 on Windows.  When i record audio via Record the screen it is speed up 200 % .  Adjusting clip speed does not fix this as I can only move it down to 50% which is still too fast.

I am getting the same issue, windows 7. Makes the product pretty much unusable for doing screen casts.

Same issue here, Windows 8.1, Camtasia 8.4. Playback is at least 200% for audio and yet the clip speed says 100% for both audio clip speed and video clip speed. None of the technical people seem to have an answer from Camtasia and the link David O'Rouke provided is broken. http://techsmith.custhelp.com/app/ans...

Hi, Knausk!

Are you working with Camtasia Recorder files or are you importing media files from a different source?

If they are Camtasia Recorder files (a.k.a. TREC files), what type of audio are you recording, a microphone or the system audio? If you are recording a microphone, what type of microphone are you recording? Is it a USB or analog microphone? Is it wireless / bluetooth? Are you using a audio interface (such as pre-amp or mixer)? One thing to note about audio interfaces is that they are not officially supported by Camtasia Studio. If you right click on the speaker icon in the lower right corner of the screen (see: http://screencast.com/t/xAyKRlbJG6ha ) and you go to "Recording Devices" then double click on your microphone of choice and choose the "Advanced" tab in the window that appears, what options are selected (see: http://screencast.com/t/0HHinYdX76 )?

I had this same problem and started doing any weird thing I could think of. It finally worked when I launched Camtasia Studio FIRST, and then clicked Record My Screen. I had the problem when I was just launching the Camtasia recorder. Hope this helps someone!

I have this problem too in Camtasia Version 9.1.5 on Windows 10. Sometimes when I do a "new recording" it records the sound three times faster than the audio (I call this the "Alvin problem" because then my audio sounds like Alvin and the Chipmunks).  It is sporadic and occurs quite often when I close Camtasia and then open it to do a recording. It just happened when Camtasia was already open, ruining my 27 minute video (because there is only 9 minutes of fast audio).  I alerted Camtasia to this problem a couple years ago and the tech support said he never heard of it.

Correction "...it records the audio three times faster than the video..." Note: I have experienced this problem sporadically at least 100 times over the past 10 years through different versions of Camtasia and Windows.

You mentioned you alerted tech support.
Did you open a support ticket and work with them?
If so, what did they tell you?
I'm curious as this has never happened to me.

Thanks. It's been a couple years since I contacted them. I can't remember if he wrote a ticket but he said he had never heard of this problem and was not aware of any fix. I think he intimated that since I was the only one who had experienced it (obviously not; see this thread), it may be a problem on my end.  See my comment below about it occurring over 3 completely different computer systems I have had in the past several years.

It would be interesting to see the audio specs for all those encountering this issue. Who knows, you may all discover that everyone experiencing it is using the same brand of sound card or something.

Thanks for the thought. I have had this "Alvin" issue over at least 3 different computers from 3 different manufacturers and very likely 3 different sound cards, so I don't think it's related to that.

Dan, you mentioned three versions of Windows. This is the Mac Camtasia forum.

Dan, 
I would contact tech support again
Alert them of the history of this problem and say you want a solution this time.
At the very least, they should request/collect some system information from you. To try  and track down a cause.

Dave, Thanks. I just googled this problem and it came up here so I posted. But it is noteworthy that this problem occurs in multiple operating systems.

Joe: Thanks.  I gave up on customer support for this problem. They really didn't seem to interested and you can see this is an old thread without a solution from tech support.  What I do is make a 10 second video and if it doesn't have the problem I cross my finger and hope the next one does not either. That usually works.

Here is what Camtasia shows the audio file vs the video file when it records the audio at 3x the video. You can see the audio file (on top) is 1/3 the length:

Interesting. It makes me wonder if it would sound normal and match the video if you applied a clip speed effect to the audio part and stretch the duration to match the video part.

Thanks. I tried doing that but I am not an expert on the details and I could find no way to stretch it 3-1. When I put a clip on it, it did not stretch it but maybe I just don't understand how that works.  But of course none of that should be necessary; I simply deleted this recording (it was only 10 seconds) and the next one mysteriously (and as always happens) was fine even though I did not change anything.
