Background air conditioning noise

Posted: Tue Jul 31, 2007 2:20 pm

I have recorded a conference where I could not switch of the air conditioning, and so there is a background hum in all my recordings, which are here:

I am a mac user, and I would be grateful for any suggestions of how I can reduce this.

Waves has a product called denoiser.

Try rolling off the low frequency, if you already haven't done it. 14 day trial demo for Waves. Try their Z-noise.
Also boost in the 3-5khz area to brighten it up a bit.

This might be out of my price league, but thanks for info on what should be done.

alternatively you can send your files to another studio for clean up.

What kind of mic is that you are using? I'm not a mic guy...but I think someone dropped a pen in the back row and I heard it:)

If you have to do more of these sessions maybe closer mic placement and some trick eq would mask it down a touch?

A pair of stereo laveliers from Giant Squid:

I am a beginner, but these are really amazingly sensitive. Perhaps too sensitive here. They were taped to the lectern. I had the option of using the feed from the main microphone, but it was mono output, so I used my own.
