LessWrong might be exempt from these fees, but the exemption is unclear. Specifically, I don't know how to interpret "other consideration of any kind". I am not a lawyer.
From the license holder's website:
5) Do I need a license to distribute mp3 or mp3surround encoded content?
Yes. A license is needed for commercial (i.e., revenue-generating) use of mp3/mp3PRO in broadcast systems (terrestrial, satellite, cable and/or other distribution channels), streaming applications (via Internet, intranets and/or other networks), other content distribution systems (pay-audio or audio-on-demand applications and the like) or for use of mp3/mp3PRO on physical media (compact discs, digital versatile discs, semiconductor chips, hard drives, memory cards and the like).
However, no license is needed for private, non-commercial activities (e.g., home-entertainment, receiving broadcasts and creating a personal music library), not generating revenue or other consideration of any kind or for entities with associated annual gross revenue less than US$ 100 000.00.
I think wedrifid is probably talking about the licensing of the text-to-speech engine he used, rather than mp3, since if mp3 licensing is the problem the files can be easily converted to another format.
I can drive and listen, but I can't drive and read! The same is true for most kinds of exercise.
If you are in my situation - wanting to read the sequences without having enough time - feel free to download these audio files for your smart phone or MP3 player.
My vision is to build a podcast feed or downloadable MP3 repository of all the major sequences. The files I have now are not organized enough to scale out to hundreds of posts, and some of the artifacts of text-to-speech could be reduced with the right pre-processing. Before I spend more time on this, I want the right tools and process in place.
Any ideas on how to to proceed? Would you like to help? How should I publish these files?
