i have some player.swf and it plays only mp3, but i need player for both mp3 and wav, is there any such player? denis, no JFlash: is there any reason or problem with it? i'm not aware of the technical reasons behind it but there's no support to dinamically load and play .wavs but i can say this? Flash is a technology intended to create lightweight interactive content ieaiaio mp3 with high decent quality might be at 1MB same thing as wav will be 10-30MB + and wav is extremely bandwidth unfriendly ( historically ) u v to reconsider not all poeple on the planet with high internet bandwidth agrees so, why the heck they'd add it. if you want .wav just use java or director or anything else :) basically adding .wav support to the FP would most probably add a lot to the player size. so they decide to not have it maybe thats the reason :) its logical hey could have evry weird features like this in the Flash Player, like wav suport and hardware acceleration, and shading , and 3d you name it
