Camtasia (Windows): Audio Waveform Not Show or Sync with Audio

Problem

When playing audio in the timeline, the audio waveform does not sync up with the audio I am hearing.

Solution

This behavior occurs with certain variable bitrate MP3 files. The best workaround is to import the file into a free program called Audacity and export it as a 16 bit 44.1khz WAV file and then use the WAV file in Camtasia Studio 8.
