The best site I have seen in regards to mp3 licensing requirements is: http://mp3licensing.com They seem to indicate that commercial use requires a license: http://mp3licensing.com/help/index.html#4 http://mp3licensing.com/help/index.html#5 I am not a lawyer, I have no knowledge if this site represents all possible patent claims related to mp3. As always, I would advise people using technologies they suspect are patent protected to seek legal advice to understand their own obligations based on their use and legal jurisdiction.

Since mod_shout encodes/decodes and audio file in the MP3 format, can someone explain to me how this complies with licensing since MP3 encode/decode software is not "free".
Is the patent holder giving a free license to use the technology since it is a open source package? Is another technology being used that does not require licensing?
