How do you insert an audacity file into a prezi?

You need to convert the files to .flv or .swf files before inserting them. In audacity, if you just save a file, it saves as a .aup file. You can open these files only with Audacity. You can, however, export the file as a different format by going to the File menu and clicking Export. Next, you will have to find either an online conversion website or download a software, such as RealPlayer converter, and convert the file to a .flv or .swf file.
