connect multiple remote sensors and play sound?

Hello!

I need to connect multiple remote sensors and each fire a playback??

The sensors are sharp to go directly to an arduino analog input.
The sounds can be saved on an SD card.
The question is how to connect arduino to sd card as the sound plays according to the activated sensor ?????

THANKS!
