For some reason, whenever I try to play a plug-in that Audacity suggested that I download, it says I need to import raw. After I import the raw data, all I hear for every plug-in is a scratching sound. I am just starting out with mixing and this kind of program, so any help is appreciated. Thanks!
You play audio files you imported into Audacity or sounds you generated in Audacity or recordings you made in Audacity.
Plug-ins enable you to run additional effects or similar.
The optional libraries you can get for Audacity are LAME (which lets you export MP3 files) and FFmpeg which lets you import and export extra file formats like WMA, AAC and AC3.
Please tell us what you are trying to do. If for example you have a WMA audio file that you want to play in Audacity, you need to follow the instructions carefully in the “FFmpeg” link above to install FFmpeg, and then when you drag the WMA file into Audacity, Audacity should import the file and show you the blue waveform on the screen.
Plug-ins are not audio files, you can’t play them.
Plug-ins provide additional features such as extra effects. Plug-ins are optional, but if you want to use them they must be correctly installed. Instructions for installing plug-ins are here: http://audacityteam.org/download/plugins but as you are just starting out with this type of program I’d recommend that you don’t install additional plug-ins just yet. Familiarise yourself with Audacity first, and then only install plug-ins if you have a specific need for that plug-in.
