Camtasia Audio lisp problem... help needed!

6 replies
I have recorded several screencasts with camtasia and a (supposedly) good Logitech USB headset w/ mic.

After recording, and before pushing the "Save" button, the audio seems fine.

When I then edit in Camtasia, there is a pronounced lisp sound (from my research I found that it is excess sibilant consonants such as "s", "z" and "sh").

I don't understand why when importing the clip into camtasia the audio is suddenly different.

When I import the clip (in camtasia format) into audacity, there is no "lisp" sound.

I tried all kinds of gymnastics, with the mic at different angles, settings, and with producing an mp3 in audacity then getting it in camtasia editor, deleting the video's audio and trying to sync the mp3 audio with the video... A REAL PAIN IN THE A..

in WIn Movie Maker, when I import the video (no audio) and audio files (mps from audacity), then sync (a real hassle), IT WORKS but is very time consuming.

QUESTION: is there a simple way to get my original camtasia recording to sound the same, after publishing to avi format?

this gets really frustrating, I would really appreciate help here...

PS: UPDATE: I just tried using CamStudio with same original settings as (Logitech USB, set audio format to 41, khz 16 bit both on recording and compression): IT WORKS FINE!! Who would think that a free software would have a better sound quality than Camtasia... [although it probably is only me not knowing how to set the audio formats...etc]

    I know what you mean about trying to sync audio done with audacity - absolute nightmare.

    Have you tried using different audio recording formats.
    When you click record the screen and the recorder tool bar appears click on the little arrow next to the Audio icon and select Options. Then in the audio tab click on advanced and choose a different audio option and try those. This sorted out my problems.

    Hope this helped

    cheers
    Mark.

      I'm experiencing a similar problem. Just bought a Logitech headset H530 USB, and the initial playback is fine, but when I produce the file to an MP4/flv I'm hearing a sort of lisp, or a faint metallic echo follow on behind the narration.
      So if we should change the audio settings, what would we change them to? There's a few options - it could take all day tryign them out and playing back... any suggestions? Is it the headset that is at fault?

    I use a Logitech USB headset with micro and works great, but as its so sensitive I must adjust the micro to 1/4 of the input, if not the voice have exactly the problem you say.

      Here is what I did to finally correct the issue w/ my logitech USB 530:

      • I lowered the mic volume input level
      • I changed the audio options settings to : PCM, 44,1 Khz, 8 bit mono
      • I published to wmv format
      That worked for me to correct the lisp sound.

      Good luck - let me know if you need more details...

    Take a look at your audio settings - the lower the setting, the lower the audio quality. Also, the default record setting on most computer sound cards is stereo. If you're using a headset mic, it's more than likely going to be mono. Sometimes using a mono mic to record "dual channel" can cause some distortion of the type you mention.

    The Camtasia audio settings that work best for me when working with a headset mic are:
    Audio codec: PCM (uncompressed audio)
    Audio Format: 44100Hz, 16 Bit, mono, 86KB/s

    You need to figure out the best audio settings for you, in Camtasia. I am using 6. version and it was a bit of pain for me to find fitting audio setup.
