Soundchannel limit

can somebody explain me this 32 sound channel limit, i am not sure i quite understand it…

does this mean i cant play more than 32 sounds at once, or i cannot externally load more than 32 sounds (without actually playing more than 1 in any given time)?

i am saying load because i am planning on preloading multiple sounds and have them ready for playback as soon as i want.

thank you!
