I'm having a terrible problem with Camtasia. I'm using a Presonus FireStudio Tube, FireWire connection on a Mac with Mojave. My microphone is AKG C3000B. When I record a screen capture with audio I'm getting TOO MUCH noise. I'm recording some tutorials, so its important to record both voice and system audio, but its impossible to use the voice I record on Camtasia during the screen capture, and I had to do the voices again at Reaper or other DAW. Theres no problems while recording at Reaper or Logic, only in Camtasia. Can anyone help me?

Thanks for the reply! :)

The noise sounds like an instrument cable (p10) is plugged in on the Presonus and I'm touching at the plug with my finger. It's continuous noise. I'll try to record something to test and upload here.

I have had audio sound issues in the past due to corrupt files. I go to Camtasia->Quit and then re-run Camastia and create a brand new file. With the new file open, I run a quick recording to see if the same problem occurs. If it does not, then you can copy the media from the old corrupted file to the new uncorrupted file and you are all set.

That said, the audio issues I have encountered are different than yours and it feels like you have an audio setup issue. Are you able to record audio with another program like QuickTime or Audition? See if the audio is still a problem there just to be sure the problem isn't localized to Camtasia.

Try playing around with the Gain on your pre-amp and the decibels on your mic.

I have a different setup than you, but here is what I use successfully:

Shure 55SH Condenser Mic (also called the Elvis Mic)
Shure X2U Microphone to USB adapter. Gain set to 100%and +45v is off

If I lower the gain on my Mic, I start to get similar noises as you do. Also, I am not a sound expert, but it feels like your audio might have something to do with reverb. Do you have other equipment turned on around you like another mic, a connected speaker, etc? If so, unplug/turn off all that stuff and check again.

Hope this helps!

Thanks for the reply, Bill! My audio is working excellent at others DAWS, including QuickTime. I have no other equipment turned on that would influence in this problem. I'll try other things today to see if I can solve this quickly and as soon as I do, I'll post the solution.

I just tried something new to me. When I change the SampleRate to 44.1 kHz, it seems to work. Before I was using 48.0 kHz and its was really terrible. I don't know why, but it all seems to be fine now.

Camtasia's favorite format has always been 44.1 kHz at 16 bits.

I created this image many years ago. In retrospect, I probably should have added a Camtasia logo to it.



I probably will {:>)

I tried it after reading something about it, but it wont fit exactly in my case. I never thought a different, but very common sample rate would cause that much noise. But im happy it worked. Thanks!

Wow, I just learned something from this. However, I experimented around and it makes no difference on my computer if I use 44 or 48. One-off my mics won’t even let me select 44.1.
