AVAudioplayer to play one or to play many?

[Endroits1]

I am working on my first app which will include sounds with animations. I want it to be very quick to play the sounds when you play the animations.

I was wondering if it is best to make one long track with all my sounds which will be loaded at the opening and then just jump to the appropriate track time? Or is it better to have many audio files that will load when you enter each page?

Thanks
