can someone write up a quick audio sample for the sdk or for me =) and the rest of the forums..
ONLY have it just play a wav/mp3 whatever filetype psp can play.. i dont know yet..
no text to screen, nothing at all..
when you run the rpogram, it just plays the audio..
thats all i want to see..keep it simple.
audio sample

that wouldn't even compile!!!!! integers dont have functions in them, and the c programming language doesnt have OOP (well, technically it does with function pointers, but the wavFile isn't a struct...)JJPeerless wrote:bleh, seems like too much work =)
how about
int wavFile;
wavFile =pspLoadWavFile("ms0:/fittycent.wav");
wavFile.play();
wavFile.stop();
there. i wrote it =) (i wish i couild do something easy like that)
it would have to be something like this:
typedef struct {
[some function pointer] open;
[some function poitner] play;
[some function pointer] stop;
} media;
media wavFile;
wavFile.open("file");
wavFile.play();
wavFile.stop();
:-P
I think what he's trying to say is that there is not built-in function to just "load a file", you have to go thru the wav file and play it as you are reading it.
Lego of my Ago!
I was working on a Memory game to learn how to do graphics, sound, input and IO. All of it was before the SDK was released, and I stopped working on it at that point, as everything was obsolete. This is some code I put together from various places to load WAV files and play them, and I'm sure it could be adapted to be used with the SDK functions:
sound.c
an excerpt from my main program
If that isn't enough to get it working, I'll upload the entire source somewhere and link it.
edit The code to do the sound was taken from a few different places, mostly links off of this board. I don't take credit for writing the code, nor do I think I could write it myself. Just wanted to make sure people didn't think I was taking credit for it. I'd just like to see a way to load WAVs in the SDK as well.

edit The code to do the sound was taken from a few different places, mostly links off of this board. I don't take credit for writing the code, nor do I think I could write it myself. Just wanted to make sure people didn't think I was taking credit for it. I'd just like to see a way to load WAVs in the SDK as well.
