DirectX and .mp3s

Recommended Posts

Is it true that Microsoft paid a great sum of money to the people who patented the mp3 algorithm to allow developers using DirectX to use .mp3s in their games without having to pay a fee to the owners of mp3?

With respect to the codec, AFAIK, yes.

Although it''s not just specific to DirectX - the mp3 codec used by DirectShow is part of Windows Media (i.e. the stuff installed when you install Media Player - if a machine you''re installing your game on doesn''t have the codec you have to install media player).

Not sure if there''s still any per-track encode license to pay.

AFAIK the license only covers Windows PC''s so you still have to pay on consoles.


An alternative for Windows platform is to use Microsoft''s WMA format, which is definately royalty free if used on Windows PCs - once again though the codec comes with Media Player rather than DirectShow so you have to include that in your installation (or point the user to the MS codecs download site - something like codecs.microsoft.com IIRC).

You can use .mp3 in for-profit applications developed with DirectX royalty free??? Wow, can''t imagine how much Microsoft had to pay for that. Last I checked any games that use mp3''s had to pay ~$3,000. Any applications that used mp3''s had to pay something like $55,000 or a rediculous per-unit royalty.
