  • Sometimes I just can't get a waveform....

    Hello,

    As the title suggest sometimes I just cant get a waveform. I make sure that the audio is selected, the arrow is selected to show it, the audio channels are clear, and the waveform button is depressed. It just doesn't generate a waveform. I can see the volume and pan controls.

    What am I doing wrong?

    Thanks

    Does it still play the audio - just the waveform display isn't there?

    Try right-clicking the clip, go into Properties, Audio, and refresh the waveform cache. If that doesn't work, fine the .EWC file associated with the clip and delete it.

      Always get audio just no waveform.

      If the original audio is on CD and not the hard drive would this cause the issue?

      I make a file in the bin area but I think that is just pointing to where the audio is (on CD).

      Thanks

        I'll answer my own question for others.

        The actual audio file must be on the HD for a waveform to be generated.

          Correct, because EDIUS needs to be able to write an ECW (EDIUS Waveform Cache) file. By design, this file must be created in the same folder as the source file. In most cases, CDs cannot support on-the-fly file writing.

            If you are talking about Edius, then I think I used to have the same problem.

            If you right click the audio stream in the timeline, goto 'properties', then select the 'audio info' tab, you will see a 'refresh wave data' button. That works for me. That is, if we are talking about the same thing!
