i don't see how for there's just not enough room in the prx.i am updating my app as wee speak for firmware 4.00 M33 when it comes out and for the 395 also but anyway the max size of the wav file that can be injected is 49376 bytes so even at 66 kps,i think the lowest you can go with the atrac3 codec but not positive it still wouldn't happen.i am not a programmer by far and if there was a way i would love to know how.
