    Is there some problem with sticky keys on your keyboard?

    How about going to google and typing in
    MP3 file format

    Not everything. A search for "Mp3 Hhheeellllpppp !!!!!!!!" returns zero matches. That could be why it didn't work for the OP.

    is it always full off people with great comments or is there some one that can actually help some one that doesnt say bs google has everything cause it really doesnt. and someone that doesnt think i have a sticky key board. just because you know what an if statement is doesnt mean you can programme are you sure you should be giving advice.

    Very well.

    >anyone know where i can find how to write to a sound card
    Use an API (DirectX for example) or find out if your sound card has its own API that you can use directly.

    >can you tell me how to decode the mp3
    www.wotsit.org. Search for mp3.

    >is it always full off people with great comments
    It depends on the question asked. Poor questions get sarcastic answers.

    >some one that doesnt say bs google has everything cause it really doesnt
    Believe it or not, google can help you to answer 99% of your questions. However, you have to use it intelligently. It's not a magic bullet that reads your mind and finds the one page on the internet that is exactly what you're looking for.

    >and someone that doesnt think i have a sticky key board
    Don't say things like "hhhhhhheeeeeeeellllllllllppppppp" and it will minimize such responses.

    >just because you know what an if statement is doesnt mean you can programme
    Mmhmmm. And the point of this other than an irrelevant personal attack is...

    >are you sure you should be giving advice
    Yes. Are you sure you should be asking for our advice since you seem to disapprove of our methods so much?

    ok if u feel u can use it more intelegently go ask it for a cross compiler in c for mp3 player any way you want to i dont mind i just want to get it. ive tried wotsit thanks for the suggestion is a great site but doesnt really tell you how to decode an mp3 very well. see thats more like a proper answer why cant you just do that in the first place.

    i dont disaprove im just looking for a more high leveled answer than look on google. more like look in such and such header file. or you can find driver handlers in this file header. you can write to that device in this way. i thought that was what i would get not go search for it.

    Well, I don't know of a compiler that has built in functions for working with mp3's at all. Perhaps you should be looking for a portable audio library instead.

    >why cant you just do that in the first place.
    Because (no offense) your question sucked and the answer could be more easily found on google.

    >more like look in such and such header file
    >or you can find driver handlers in this file header
    Such an answer would be assuming that you had the library that defines the header.

    >you can write to that device in this way
    What device? You didn't specify anything but "sound card". We can't be very specific about writing directly to hardware without the specifics of the hardware.

    p.s. Try searching google groups. I get plenty of hits for mp3 decoding in C. I didn't read them thoroughly though.

    see thats why i wish i was using linux as it does have a header file that tells you all about your sound card but i dont know if windows does i might just do it in linux as it is so much easier to cross compile.

    Since when? Linux comes packaged with headers for each sound card? What's the header used for the Turtle Beach card? Or the Audiophile 2496? I haven't run across anything like this on linux? Heck, I had trouble with my sound card and linux wasn't all that helpful.

    Someone should add a "How to use Google" tutorial to this site. On the other hand, maybe not, we couldn't look like "experts" if just anyone could go and get the information from Google/MSDN/Man!

    Check-out LAME, and search SourceForge for other mp3 projects.

    You could also try searching Programmers Heaven for some sample code.

    Note that the mp3 format is not "open source". You're supposed to pay a liscencing fee if you "distribute" your application.

    Also, don't expect the mp3 format to be simple! I think the compression & encoding algorithms are rather complex.

    There are lots of ways to communicate with the sound card. The MMSYSTEM (Multimedia System) commands should be included with dev studio. Or, you can use DirectX/DirectSound. You might have to download the DirectX SDK. Unfortionately, I don't have a reference that covers all of the sound-related functions.

    ok, i did a google search for mp3's and c++ and didn't find much, so i stand corrected. the overall tone from your post may me think you were just too lazy to look for yourself, so im sorry. you may consider looking into fmod (www.fmod.org). haven't used it myself but i hear it's fairly powerful and very easy to use. a lot of opengl stuff i've looked at recently uses it for music. also im pretty sure it's free for non commercial use...
