I tried most things here  none worked on my Ubuntu VM  Here is a quick hack  credits goes here    include  lt iostream gt  int main       system  quot  speaker-test -t sine -f 1000  amp  pid     sleep 1 0s  kill -9  pid quot       It will basically use system s speaker-test to produce the sound  This will not terminate quickly though  so the command runs it in background  the  amp  part   then captures its process id  the pid  1 part   sleeps for a certain amount that you can change  the sleep 1 0s part  and then it kills that process  the kill -9  pid part   sine is the sound produced  You can change it to pink or to a wav file

If you re using Windows OS then there is a function called Beep     include  lt iostream gt    include  lt windows h gt     WinApi header   using namespace std   int main           Beep 523 500      523 hertz  C5  for 500 milliseconds          cin get       wait      return 0       Source  http   www daniweb com forums thread15252 html  For Linux based OS there is   echo -e   007   gt  dev tty10   And if you do not wish to use Beep   in windows you can do   echo   G    Source  http   www frank-buss de beep index html

There are a few OS-specific routines for beeping    On a Unix-like OS  try the  n curses beep   function   This is likely to be more portable than writing   a  as others have suggested  although for most terminal emulators that will probably work  In some  BSDs there is a PC speaker device   Reading the driver source  the SPKRTONE ioctl seems to correspond to the raw hardware interface  but there also seems to be a high-level language built around write  -ing strings to the driver  described in the manpage  It looks like Linux has a similar driver  see this article for example  there is also some example code on this page if you scroll down a bit    In Windows there is a function called Beep

You could use conditional compilation    ifdef WINDOWS  include  lt Windows h gt  void beep       Beep 440  1000      elif LINUX  include  lt stdio h gt  void beep       system  echo -e   007   gt  dev tty10       else  include  lt stdio h gt  void beep       cout  lt  lt    a   lt  lt  flush     endif
