For certain reasons, I need raw audio data in my application. I would convert certain sounds to a PCM format (at development time), and store & load these PCM files in my game.
PCM stands for Pulse Code Modulation, and as far as I can see, it is a representation of signal, and thus cannot be patented by anyone. Only formats can be patented I suppose (e.g. WAV, which relies on PCM), but PCM sequence of bits cannot be.
So if I include PCM data in my application package, I don't violate any patent, do I?
I'm developing for Android, by the way.
