Audio wave representation misaligned with sound after Audacity filtering

(Attempted to open a ticket at, but kept getting "Problem loading page" and "The page isn't redirecting properly")

After recording a speaking voice, I filter it using Audacity to clean up the sound. That seems to do a better job filtering out the noise. After importing the cleaned audio file into Camtasia 8, the graphical representation of the sound wave is misaligned. The sound starts right away, but the graphical wave for the beginning of the sound is about 5 seconds later.

This makes it very difficult to align with the video portion.

Hi Carl!

We're currently looking into some issues with our ticketing system; hopefully things will be back up momentarily.

I see you have an MP3 file on the timeline; would you be able to share the properties for the file? Does it contain a variable bitrate? What is the sample rate?

Audacity can export a WAV file that works wonders with Camtasia; can I have you open your Audacity project up then go to File - Export Audio and export the file as a 16-bit, 44.1 kHz WAV file and use that in Camtasia instead of the MP3 file?

I recommend always using WAV audio right up to the end to preserve fidelity and then it will be compressed later during the rendering process.

Rather than endure the side effects presented by this workflow, why not record in Audacity and import the audio in a more trouble-free manner?

Hello there Carl,

Here is the workflow I use to clean up my Narration work. It ensures that all audio tracks will remain in sync with the timeline.
I use Adobe Audition myself but the technique works because the audio is exported and imported as one continuous file that spans the entire timeline.
Just place the new file on the timeline and delete the original files when you are confident that the audio lines up correctly.

Camtasia works best when you Export your audio files from other programs using these settings. I like to call it the Holy Grail of Camtasia because you won't encounter any compatibility problems.
