Sound removal recommendations.

[Havok26]

I recently recorded a speach using my Cannon MiniDV camcorder. I copied the video via firewire and Windows Movie Maker to my system using the 25Mbit AVI option. I had a direct line-out from the sound board at the event to my mic-in on the camcorder. Unfortunately there was some sort of feedback in the system and the entire video has a nasty humming in the background that can even make the speaker hard to hear.

I want to encode the entire thing eventually to mpeg-4 with wmv9. Audio will probably be wma or mp3. Whats the best method to get rid of the humming in the audio (or at least lessen it)? I would like to avoid too many instances of compression/decompression from using a ton of applications to do this. I'd appreciate any ideas or recommendations for this process. Thanks in advance.

I know only one way to destroy noise and other things which is constant showing in sound. The solution is Adobe Audition's(Cool Edit) noise reduction.

Hi!

You might want to check out the noise sampling and removal capability of (freeware) "Audacity"...

"I had a direct line-out from the sound board at the event to my mic-in on the camcorder."

The mic-in input is only for microphones, hence the name. If you put a line signal into this, you will get horrible sound quality. Use the line-in instead of mic-in. If you don't have a line-in, you're basically screwed.

Best thing is probably to merge the audio and video in software, in order to avoid moving the sound through any wires.
