Have you ever wondered how recording artists get that muffled/distorted sound in certain types of recordings (many times on a voice during a bridge)? Well I found an effect in Audacity that has a very similar sound.
NOTE: I’m assuming that you’ve already downloaded and installed the LADSPA Plugins for Audacity from their website. This package contains 90 useful plugins for Audacity. If you don’t have it yet, go to this URL, choose your operating system, and click on the LADSPA Plugins link. Install that and you should be good to go!
