Where can I get a version of the Fraunhofer codec?
If you go to www.winfiles.com and from their search page search for a program called “l3encwin”, you can download it, and you will find that it has the old Frauenhofer l3enc.exe and l3dec.exe included with it (l3encwin is a front-end for the Frauenhofer codecs… but it can’t access all the features). If you put these files, as instructed by the “readme” that comes with l3encwin, into your windows directory or any directory on your default path, you should be able to use them.
