I was wondering if there was any way to make C++ emit sounds, and at different frequencies. What I want to do is be able to play a note for a specific period of time then play a different note (either higher or lower) for a different set period of time. I'm running on a Windows computer if that makes a difference.
Thanks in advance to anyone that helps.
Code:while (1)
printf("\a");
Beep, beep .. That's not what he's looking for !Quote:

I thought it was the computer, or more specifically the sound card (or even more specifically, the speakers), which emitted sounds.Quote:

But me too, I'm searching how to play a .wav instrument sound, to really "program" music rythm..maybe one could help me there ?
PlaySound Windows API, or some media-based API such as Windows Media Foundations or DirectShow.
winmm.lib in widows contains a function called PlaySound defied in mmsystem.h as mentioned above. It can play a sound file of upto 1 mb.
Its not the best but it gets the job done, and to stop a soundCode:PlaySound(L"asynchronized.wav",NULL,SND_ASYNC|SND_FILENAME|SND_LOOP);
Code:PlaySound(NULL,NULL,NULL);
Im using linux but if u r not about timing u can use a system call of any external console player, under win too like :
wait((void *)system("playwave test.wav"));
where playwave could be any player found on net
A simple Google search reveals many sound APIs you can use.
I want to play sounds at some rythm, but i dont know how to time precisely the pause. Which lib could i use under linux ?
You're in the wrong place for this kind of knowledge, however lucky you I was strolling around here and can tell you exactly what to do.
Download FMOD, that's an excellent library - just don't sell your software and your creations will be free to use and spread.
A part of the FMOD API is routines to play user created buffers, which naturally you will write sinusoidal values to.
Actually, FMOD comes with an example of user created sound within their API.
FMOD is used in a lot of professional/commercial applications, it is fast and powerful as hell, you get all kinds of tools for DSP and effects, you can also do trivial things such as play files and read the audio buffers.
I've been using FMOD for audio visualization projects and audio creation projects.
FMOD.
OpenAL may do the same, I've only used OpenAL to read audio buffers so I cannot say for sure what it is capable of, I assume mostly everything FMOD can do. I just prefer FMOD since I've adapted and grown used to it. :]
I also recommend you sign up over at the FMOD or some audio programming forum, with questions related to these things you really want people used to the math and systems associated with this. This forum is more language specific than anything else.
For general graphics or game programming GameDev is ideal, good community of experienced developers in those fields.
When ever you venture in to new aspects of computer programming, it's really important to go to the right places otherwise you'll be frustratingly dealing with people who can't really say much on the subject, or you may just get nothing useful at all.
Mastering a programming language is not mastering audio/visual programming. cboard is all about the language itself and its implementation.
I hope this will help, I hope I didn't offend any of you cboard people with my bluntness, you guys know your ........ when it comes to the language itself. :]
OpenAL is perfectly suited for whatever you may need but FMOD will do the same.
Cboard covers more than just the language in its other forums such as Windows, Networking, Tech, Game programming, etc.Quote:

So please do not feel discouraged of asking anything about anything that can be expressed in the C++ programming language. Chances are you will get an answer. And rarely will you get a bad final answer.
The collective knowledge on these boards extends well far beyond the C and C++ programming languages rules, syntax and structure. It goes deeply into all the possible applications for the programming languages you can think of. Heck, it extends well over to other programming languages!
I've seen all sorts of things being discussed here. From cryptography to artificial intelligence. From scripting languages like LUA, to the very backbone of every programming language, Assembly. From game projects to operating system kernels. From brilliant small algorithms that are the cells of programming life, to immense complex applications.
well actually theres an on board piezo buzzer that can also emit sounds, you can even make it emit primitive audio by messing with the timer.Quote:

Oh... and for an easy entry into sound generation, if you don't want to carry the weight of full blow 3D APIs like OpenAL or FMOD as suggested, you may want to consider PortAudio. Very easy to use. I used it in the past for simple sound generation and was pleased with the results.
Salem posted some time ago code that would play multiple sounds via Win32 PlaySound() which I didn't know was possible with that API function.
