so i am programming for 2 years and i would like to use "sound" and "graphics" in my programes.
i know the sound function and the graphics library in borland but after all it's borlan XD
so I need you to recommend about an simple graphics (2D) interface and i need you to give me an example for using sound in C (I heard a little about the beep function).
thx!! [:
* hope I haven't pass the rules.
SDL can do sound and graphics. Although for sound it does little more than play mp3s.
thank you, I'll check it later.
still open for recommandations..
There is the sound() function for Borland, but what you want is a music maker. Making music with sound() would be extremely laborious. Any program that can make music, will show you how to play that music, of course.
This is the Borland C help file for sound:
Have you googled for music making programs and libraries?Code:sound Turns PC speaker on at specified frequency.
Syntax:
void sound(unsigned frequency);
Prototype in:
dos.h
Remarks:
sound turns on the PC's speaker at a given frequency.
frequency specifies the frequency of the sound in hertz (cycles per second).
To turn the speaker off after a call to sound, call the function nosound.
Return Value: None.
Portability:
sound works with IBM PCs and compatibles only. A corresponding function
exists in Turbo Pascal.
See Also:
delay nosound
Example:
/* Emits a 440-Hz tone (A above middle C) for 1 second. */
#include <dos.h>
int main(void)
{
sound(440);
delay(1000);
nosound();
return 0;
}
You will need a 3rd party library or engine to do sound.
You may want to check out OpenAL.
I think i wasn't clear enough, i don't wanna play\create music (like mp3), just sound in hertz..
I'll very glad if you give me links or something for what you are suggesting.
thank you both.
Making sound in hertz is just what my last post's code and help was all about, what do you mean?
Read the part in the code tags, and try the example code, in it.
Beep() perhaps? http://msdn.microsoft.com/en-us/libr...77(VS.85).aspx
putchar('\a');
Gone are the days when you could hook a timer interrupt for timing and use the 8 khz PC speaker for sound based on the timer - or are they? A friend of mine at work coded something like this a very long time ago. Surprisingly it still works in a DOS window. He fires it up every now and then and we have a ball listening to some good old fashioned 8 khz PC speaker music. He actually encoded some old AC/DC songs. Just consider it an ancient form of MP3.
that's what I want but this function is from borland (I use dev C++ and I prefer to have standart codes).
for beep I must know api first?
API is complicated )=
rob, I have seen what you wrote somewhere but how do i control the sound? (if you can give me more details).
last and likeable
I didn't get you or you didn't get me.
I am not traing to play songs XD
thank you all [:
Win32 API maybe?
The manual page is pretty straight forward (http://msdn.microsoft.com/en-us/libr...77(VS.85).aspx). What do you want to know?
If we wanted to implement Windows "Beep" in Borland code, it would looke like this:
I don't think that makes it hard to do or deal with.Code:BOOL WINAPI Beep(
__in DWORD dwFreq,
__in DWORD dwDuration
)
{
sound(dwFreq);
delay(dwDuration);
nosound();
}
Obviously, learning the ENTIRE Windows API is complicated, but understanding individual functions is (generally, and certainly in this case) simple.

I compiled this code (with borland)
and all I heard was the silence..Code:#include <stdio.h>
#include <dos.h>
int main()
{
sound(700);
delay(3000);
nosound();
return 0;
}
when I tried to compile the API part I got errors.
Can you get other sounds out of the system? Is the PC speaker connected?
The Beep() function requires that you include <windows.h>

Sadly, many mobo's and cases don't have much for built in speakers. Mine has a tiny "speaker" type of thing about 1/2 inch around on the mobo. (no internal speaker on the case). When I run this program on it, it does play the sound, but it sounds faint, and rather tinny, reflecting the tiny size of the mobo speaker.
But that's the speaker's limitation, not the program's. This is on a WindowsXP box, btw.
For better sound, you'll have to either get a real internal PC speaker (about 3 inches across), and connect it to your mobo, or get the output of the program routed out to your external speakers.
Does anyone know how to do the latter?
> rob, I have seen what you wrote somewhere but how do i control the sound? (if you can give me more details).That's about as much control as you're gonna get.Code:void beep_num_times(int num)
{
int i;
for (i=0; i<num; i++)
putchar('\a');
return;
}
ok thanks.
humm first of all mat, the speaker do was connected (I am not so fool XD)
ya I know.
have I mantioned that I want my program to run on linux too (I forgot the word)
Adak, you are a little bit complicated XD
rob, I got you.
by the way it's better to use delay instead of the "for"
ohh and the sound doesn't have to be heard trough the speakers, It can be heard trough the processor..
Erm, a delay does something different from a loop. If you want to play more than one beep you will need a loop. Maybe with varying delay times.Quote:

The processor doesn't emit sounds... unless you blow it up.Quote:

So with the right programming, you could have it play your favorite music, but it wouldn't sound like a good stereo would sound, believe me. :)
Your processor sends the stream of commands to the speaker, so it can play sounds, but the cpu itself, can not play any sounds.
A "beep" or '\a' in C, is just a beep - it is not sound that can be used to play music. It's just noise. Beep and sound should not be confused, or mentioned together, except to note that a beep is not a single pitch (frequency), of sound. Sound and beep are very different things.
> It plays music, but it doesn't equal the sound of the old PC internal speakers.
In other words, the world of technology is traveling backwards :)
If you want to play sounds I suggest you use normal speakers -- the Beep() API isn't supported in Vista x64 anyway.
Bubba has already suggested OpenAL, which I'd recommend -- or libbass or fmod.
why the program that Adak brought me and the program that Rob brought me doesn't work?!
"A "beep" or '\a' in C, is just a beep - it is not sound that can be used to play music"
that's what I am traing to do, I don't wanna play music..
zac what you brought me isn't simple at all, I just want to "play" frequency.
Because there is something missing in your hardware setup? If your system doesn't have a speaker (or the speaker is not connected, broken, etc), then you are not going to get a sound out of it.Quote:

yo dude I got confused @_@
Everything seems to be ok, I use my speakers everyday..
and what is the difference between "beep" and "messagebeep"?
There is a difference between "the speakers" and "the PC speaker". The latter is a speaker inside your PC case. the former is where the sound comes from when playing an Audio CD or an MP3.
The main difference between MessageBeep is that it plays the sound in "the speakers" (except if you don't have a sound card and you use -1 for input - in which case it uses "the PC speaker"). Beep on the other hand is using "the PC speaker" all the time.

Thank you for the patients.
So I need the "beep" function.
but as I mentioned in my last post - it doesn't work :(
You don't have Vista x64 do you? If so then it won't work.
Otherwise you could be playing a frequency that you can't hear or the speaker can't play.
Beep() is definitely the wrong path to take. You've been told how to do what you want. Perhaps heeding some of the suggestions and trying them out would be better than insisting they are not right for you....without having tried them.
Nope, I don't use vista at all, I use XP but I am planning to stop this "bad habbit" and use linux.
Give me a frequency that I can hear, so I'll try again.
I need the whole code for an example so I could understand, cause as I said I don know API or what ever you wrote.
thanks again.
In other words you haven't tried...
Read the manual, it's pretty straight forward. It's not going to teach you C, it will tell you how to use the API though.
I tried the sound function (borland).
I'll try this too.
The borland code I posted, definitely works on WindowsXP --- if you have an internal speaker. You may need to take off the side of your case and get in a quiet room to hear it though. It is quite soft, if you have one of the modern type of speakers (the 1/2 inch around type).
My compiler (dev Cpp) doesn't recogonize the "DWORD"..
Code:#include <windows.h>
#include <winbase.h>
BOOL WINAPI Beep(
__in DWORD dwFreq,
__in DWORD dwDuration
);
int main()
{
sound(100);
delay(2000);
nosound();
getchar();
return 0;
}
That's strange, as they should be declared in windows.h - and you shouldn't need to:Quote:

Did you mean to have two spaces before DWORD, or just one?Code:__in DWORD dwFreq,
__in DWORD dwDuration
certainly works on XP (I just tested it) when compiled with gcc-mingw 3.4.2.Code:#include <windows.h>
int main()
{
Beep(1000, 500);
return 0;
}
If that makes no sound when compiled with dev-c++ using gcc, then you haven't got a speaker inside your PC, or it's not connected correct (or something is broken in some other way).

Why would that make ANY difference?Quote:

Humm "sound" "delay" and "no sound" doesn't work at all,I think they need "dos.h" and to be compiled with borland only.
Anyway I tried this one:
No errors or warnnings but I didn't hear any sound ):Code:#include <windows.h>
int main()
{
int i;
for (i=0;i<100000;i++)
beep(i*10,200);
getchar();
return 0;
}
beep or Beep - note that C is case-sensitive, so "beep" and "Beep" are not the same function.Quote:

Both of them can make only silence.
I feel so stupid "><
Have you tried to compile my code with your compiler?
No, but aside from Beep instead of beep, I don't see anything wrong with it. I'm not going to subject my colleagues with an incrementally increasing frequncy from around 20Hz to 1MHz for several minutes either.Quote:

lol
I don't expect you, me or anyone else to wait till the programm ends.
When I am using Beep, where should the sound be heard from?
From inside the comp' speakers or from my regular speakers?
Inside the computer.
So how can I check if I have this speaker?
You said you knew you had it!? Give up on the idea of using the speaker inside the PC.
Use the libraries that others have been suggesting.
I thought we were talking about the outside speakers.
OK, I'll try.
Any of the basic inbuilt sound commands like putchar('\a') and beep() will only work with the internal speaker (the thing that beeps when you start your PC).Quote:

OK.
Thank you all.
