A440 Posted June 28, 2006 Report Share Posted June 28, 2006 Audacity (free from Downloads) has Noise Removal under Effects. What you do is select a part of the recording that is ONLY noise, and it compares that to the rest of recording and removes what it thinks is noise. Sometimes it improves things; sometimes it doesn't. It depends on if you have a part of the recording that's pure noise. Quote Link to comment Share on other sites More sharing options...
Shozzer Posted June 28, 2006 Report Share Posted June 28, 2006 What sort of mike did you use and what sort of noise are you talking about? Quote Link to comment Share on other sites More sharing options...
BartVL71 Posted July 5, 2006 Report Share Posted July 5, 2006 If you're talking about crowd noise: you can't remove it if the noise is made at the same time of the music. If the noise is only in-between songs: you can try to lower the level of the noise (in order to make it less annoying) by removing gain or limiting.

A440 Posted July 5, 2006 Report Share Posted July 5, 2006 The initial question was about a lecture. Since a lecture is speech, it's within a narrow frequency range. A noise removal effect might help to remove sound that's not in that range. Another way to do it would be to use EQ to bring out whatever frequency the lecturer's voice uses, or use filtering if you can figure out what pitch/frequency the lecture uses.
