Noise reduction with audacity
I recorded some interviews for my PhD thesis during OpenExpo (in Bern). The background noise unfortunately was very loud so I had to concentrate very hard while listening. Audacity has the nice effect "noise reduction". I tried it and normalized the track afterwards. The difference is magnificent. Now it's easy to understand the answers to my questions, althou the voices sound a little bit unnatural now (but that doesn't matter).
