    I just shot my first short over two days. On the first day I used AC power and I have a nasty hum over all my audio. I had an external mic but my cam doesn't use XLR. From what I've been reading I probably have 60hz electronic hum but I've tried SoundSoap's 60Hz and 50Hz hum remover and it does nothing. When I do learn noise it does a bit better and turns on the broadband filter but it still isn't great.

    I just got FCE and I'm totally lost. I'm an iMovie guy...I dragged the hum remover audio filter to my clip and render but it doesn't seem to do anything. I don't hear any difference in my clip. What am I doing wrong?

    Can someone send me step by step instructions on how to use FCE's audio filters to clean up my audio? Or maybe we can do an iChat one evening?

    you should be able to double click any video file in the timeline and it opens in the viewer (the left window, the right window is the canvas and shows the timeline)

    in the viewer should be some tabs along the top, one is filters, anything you apply should be there. The controls to tweak are also there, but Final Cut doesnt do dynamic previews, so you cant be playing the audio and move the paramaters around, you have to tweak, play, tweak play.

    hope that helps, its a quick synopsis.

    Do you have a sample of the noise for us to play with?

    Zip up an MP3 sample and attach it here.

    if its really a constant hum, a hum remover or almost any combo of the right audio filters will remove it. he just had a problem understanding the use of the filter in FCP.

    The noise is louder than the voices. That's going to be tough to fix in FCE. Quite honestly, I don't think it's possible with the filters available in FCE, since the noise is broadband. You need a multi-band limiter such as available in SoundSoap.

    So, I ran the file through SoundSoap instead. This is about as quiet as I could make it before the voices started sounding like they were speaking underwater.

    Thanks for running this thru. Can you explain to me what broadband means? Does that mean the noise is at many frequencies?

    It seems that this should be 60Hz electronic hum because I only got this problem when I had the camera connected via AC power. But, I also see in SoundSoap that it classifies the noise and broadband.

    The other interesting thing is that I found a Windows app called WavHum that says it elminiates 50Hz/60Hz electronic hum from Wav files. I converted my AIFF to WAV and ran it thru WavHum and it did a great job. Much better than SoundSoap or Audacity. It basically kept the voices.

    Why this $20 shareware able to do it when the $99 SoundSoap can't and FCE can't? I'm so confused.
