I'd like to increase the levels on an audio track that I've slowed down to 50% but I am prohibited from doing so because of a resultant hi-pitched background noise that seems to occur due to the speed change. I tried using a couple of the FCP audio filters (the ones for 'hum remover' and 'high pass filter') - does anyone have any suggestions for this problem? Using FCP 5.0.4.

Any help would be greatly appreciated!

    I'd try the filters on the raw clip, before you slow it down. It's probably some sort of radio interference

    Do you have Soundtrack Pro? If you do, you could use the Stretch Tool to slow the audio down without any pitch change. Might help, might not.

    In Chapter 7, page 160 of the online manual, there's a little blurb about it.
