How to upload audio files using Paperclip in Rails 3?

I'm very new to Rails. Basically, I have a Sound model that uploads an audio file(wav) and store it somewhere on the local machine (for testing). How to set it up using Paperclip? I googled but unfortunately most of the tutorials are about image uploading:-(

Any inputs are greatly appreciated.

Paperclip is an easy file attachment library for Rails Applications. Attached files are saved to the file system, database or cloud and referenced in the browser by an easily understandable specification.

                    :url => "/assets/:class/:id/:attachment/:style.:extension",
                    :path => ":rails_root/public/assets/:class/:id/:attachment/:style.:extension"

end
