Audacity is AWESOME!!! It's perfect for removing background hissing on cheap mics. For any of you who have a lot of hissing or humming coming from your mic when you record podcasts or demo videos for your startups. Audacity can take it out in just a few clicks using its noise removal filter. Just remember, whenever you start recording an audio track, wait 5 seconds before you start talking, and then use those 5 seconds of hissing to build a profile using the noise removal. And apply that to the whole track. My brother and I were blown away at how well it took all the hissing out. I recorded on a $9 Walmart mike and it sounded like studio quality work. Crisp, clean voice, pure hiss-less silence between sentences. Thank you and all of its developers. Audacity is a perfect example of easy to use, easy to learn, open source software.
