Subject:RE: remove noise from record Reply by: rraud Date:5/21/2003 5:48:56 PM Yes, but you will have to get the Noise Reduction plug-in. Download the demo to see if it will help your particular situation. Noise Reduction-2
Subject:RE: remove noise from record Reply by: daarrid Date:7/4/2003 1:18:53 PM You can also use EAC (Exact Audio Copy) freeware to remove noise from a recording. This program is primarily a "ripper" but has some great basic editing tools for wavs. It can be a bit tricky/less than intuitive to use, but no more so than Sonic Forge and I was able to remove noise to an amazing degree using this program. EAC is amazingly good and unlike the waste amount of junk that is free, this program is worth paying for yet the author only asks for a postcard to thank him (seriously). I would pay for it. Within the MP3 community, this is the ripper of choice. Tutorials are available. EAC uses the method Sonic Forge uses in their plug-in. First you give the program a small sample of the noise in the recording (perhaps from the beginning or end of the recording, any sample without actual music/voice in it. Then the program subtracts that from the recording. I can't recommend EAC highly enough for its noise reduction - works perfectly.

If the noise is present in the same range as the voices you will have inevitable effects on the voices when you remove the noise. This is probably not critical for spoken work. With music it's more of a problem. You start losing highs as you reduce noise. You might try using the EQ, parametric and graphic. If the noise is a low frequency thing start rolling off the low end and check the effect. Do the same on the high end if the noise is present there. Eric
