Differnce between wav libs? WAVEHC & AF_WAVE?

[xl97]

I am new to Arduino all together.. but my goal is to use these lib's (or any other that is available that people recommend?) to playing .wav files off my uSD card..

my question is what are the differences between these two lib's? and is one preferred over the other? (and why?)


also.. reading through some of the functions/methods available (from the examples page)..

1.) looping a signle .wav file? is this like a seamless 'loop'? or is there a break/pause between starting/playing the same track again?

2.) the exampel where you can play/loop 1 .wav file and let another file/button interrupt the current file being played to play another/new .wav file... once this new/injected .wav file is done playing.. does it return to the original/initial .wav file and continue playing/looping? (from where it left off even perhaps?)


thanks
