Hi, I’m using OSX 10.7.5 with a recent download of Audacity 2.0.5 using the .dmg installer. I’m new to using the software and have searched around the forum and manuals but cannot find an answer to my question.
I recorded an interview using two two ZoomH1 recorders and two microphones. My mic was handheld and produced a great sound. The person being interviewed wore a lapel mic which was pretty good but I could hear a very slight hum on that recording and her voice seemed to have a slight echo too compared to my voice on the handheld. I would like to remove the hum and echo from the lapel mic recording so that the two voices/tracks are a closer match. I watched a Udemy tutorial that showed how to reduce noise by selecting a ‘silent’ section of the track between vocal sections (i.e. a section that was a slightly thickened straight line), then generating a noise profile and then applying noise reduction to the whole track. When this was done in the tutorial the thickened straight line in the ‘silent’ section became thin indicating that any background hum had been completely removed. But when I apply the same process to my recording the thicker straight lines/sections between vocal sections don’t become any thinner - i.e. the soft hum is not removed. I have tried adjusting the noise reduction settings but this doesn’t seem to change the outcome. I would also like to reduce the slight echo on the lapel recording but can’t find any tools in Audacity that allow you to do this. Any suggestions would be greatly appreciated. PS. I would like to continue to use the lapel mic on the people I am interviewing because it allows for greater flexibility when doing interviews. For example the lady I interviewed is a professional public speaker who is most comfortable and expressive when standing up and on the move - in this instance the lapel mic was perfect for her. Thanks again.
