Audio Editing and Effects

When creating a video, it’s important to capture good, quality video. But, it's just as important, if not more so, to get good quality audio.

  • Our ears almost always detect an audio error but, our eyes are not so aware of errors occurring on-screen.
  • Most people won’t watch a video if the audio is bad – even if the video itself is very good.
  • People are more likely to continue watching a poor quality video if the audio is good.

Tips for Getting Great Audio

  • Use the best microphone you can afford.
  • Use default Camtasia Recorder audio settings.
  • ALWAYS do a short test recording to ensure audio is being recorded.
  • Use Audio Effects to enhance or correct audio.
  • Add audio points to enhance certain areas of the waveform.

There are two ways to work with audio in Camtasia: edit directly on timeline, or add effects.
