Hi fellas ,
I want to know how to generate sound or ring tone via cpu like the way we did in Borland
turbo C complier's sound(),delay() and nosound() functions.
I am using devC++ and want to know libraries by which we can play with motherboard
and generate ring-tones.
best regards,
Chakra
Windows Beep(int hz, int duration) will do the combination of sound() and delay().

thanks for quick reply. :)
...and thanks for the link for those who browse other people's questions for learning new tricks... ;)
if you're looking for something besides a simple tone like a beep, the waveout functions are *fairly* straightforward. i'd be happy to share the code i've written for using them, but it's still in a scratchpad kind of state - not elegant whatsoever.
Just a warning in case Beep() doesn't work as expected...
I remember that Beep() has some strange "if" conditions. I seem to remember that if you have a soundcard installed, you'll just get the "Windows default sound" from your soundcard-speakers... But, that may only happen with some Windows versions (maybe it was only a problem with Win98 or WinNT ???).
The old Turbo C functions won't work because the new Windows versions (newer than Win98) don't allow user mode programs to directly access hardware. (You need to access hardware through a kernel-mode driver.)
M37h0d : thank you so much for help.
please give or pm any code you have regarding generating ring tones.
DougDbug : thanks for the info. :)
However , I did the same way what DougDbug explained here but was not impressive tone.
I want to create some the movie 'mission impossible' like ring-tones.
I was wondering how to do calculation to generate sounds.I did some random stuffs.
UNTESTED (since I'm not running Windows) -
Is that Mission Impossible?... either that or Batman or Spiderman.Code:#include <iostream>
#include <windows.h>
void b() {
std::cout << '\a' << std::endl;
}
int main() {
while (true) {
b();
Sleep(1500);
b();
Sleep(1500);
b();
Sleep(500);
b();
Sleep(500);
}
}
I tried to play with assembly language to generate sounds but it's a big pain in neck.I don't
want to remember horrible instructions to generate a simple ring tone. LOL
So I want the calculation tips to generate sounds.Please provide me any charts or something
like that.
best regards,
Chakra
Why assembly?...
If you want to generate "real" music, you'll probably need to use some sort of a sound library.
I am on .net bro , I want to have fun with PC internal speaker.I am using Beep() function
via Dll-import technic of C#.I am not even using c++ .... I am just converting yours
tips to C#.Currently I have no serious reasons to use c++ exclusively because my job lies
to web and commercial application development.I love c/c++ but I got no time to play with.Maybe in future ,I will battle with only on c++ grounds. ;)
Why I tried to play with assembly I don't even know why.Even the program did not compile
on my system and I don't want to know why. LOL
best regards,
Chakra
So I can play guitar tones using these 'beep's' ? Like, can I pitch the sound xP that'd be kinda cool, even tho Guitar Pro is already made, and is prolly easier to use than this xD
Sorry to interrupt this thread, but what the h377 is xP and why does it riddle every post you make????Quote:

as i said before, the windows wave* functions are really pretty straightforward.Quote:

notes in even temperament (the more or less standard tuning scale used for most keyed instruments) can be related to each other by a factor of 2^(n/12) where n is the difference in number of semitones (notes, including sharps/flats).
the note A is an integer. A4 is 440 Hz.
here are the msdn and other webpages i've been using so far:

i also found this, but decided i'd rather learn the low level stuff first rather than someone else's library

OpenAL will do this in much fewer lines of code and with less pain. Combine that with freealut which loads wav files and there really is no substitute.
Bubba and M37h0d thanks for your precious information. :)
What you explained me is beyond my question. Hehehe
What I actually wanted was to generate sound from internal PC speaker.Just a ring-tone nothing
more.Well I am not serious c++ programmer.I have only played with Turbo C++ not high and
heavy APIS. ;)
Well I got the function Beep(int,int) which does that.But I don't understand how to put values
on it what I got from a ring-tone web-site.
for ex:
Code:g,8p,16a#.,8p,16g,16p,16g,8c6,8g,8f,8g,8p,16d.6,8p,16g,16p,
16g,8d#6,8d6,8a#,8g,8d6,8g6,16g,16f,16p,16f,8d,8a#,2g,4p,16f6,8d6,
8c6,8a#,4g,8a#.,16g,16p,16g,8c6,8g,8f,4g,8d.6,16g.
I am curious to know how sound() function works.If you have time and goodness
please explain me.

either way the self-quoted excerpt above is relevant to your interests.
e.g:
if A4 = 440Hz, what is the frequency of C4?
counting the semitones, we have: A#,B,C = 3
therefore C4 = A4*2^(3/12) = 440*1.189 = 523.25 Hz
thanks for the method , you told me exactly what I was looking for. :)
