How to make a long beep in c++?

Question

I'm making a program in c++ that reads Morse Code and prints it to the terminal, and gives the user the option to hear it. I know that, in order to make a "beep," you can use:

cout<<'\a';

However, since Morse Code contains with longer and shorter beeps, I would like to know how to make longer beeps than what would be produced by this command.

I'm using a Mac.

@FredOverflow, How about... oh wait, `long long long is too long for GCC`. — chris, Apr 24 '14 at 16:30
I have no objection to humor, but you should flag it as such so people won't think you are being helpful. — Dale Wilson, Apr 24 '14 at 16:31
You might want to use a serious audio library, such as OpenAL, depending on how much functionality you need. http://en.wikipedia.org/wiki/OpenAL — glampert, Apr 24 '14 at 16:48

If you write multiple bells. i.e. cout << "\a\a\a\a" it will come out as a longer beep.

However you also need a way to write the "silence" between the beeps, and the bell sound may be different from one environment to another, so this is not really a good approach.

There is no standard library support for controlling sound on the computer, but if you look for platform-specific functionality, you are likely to find it, and ultimately this will give much better results.

A Mac will play the system alert sound for each beep, so they won't in general combine to a long tone. Macs don't have motherboard piezo buzzers like some machines do. – Potatoswatter Apr 24 '14 at 16:42
Hence my comment that "the bell sound may be different..." – Dale Wilson Apr 24 '14 at 18:59
