it is really minimal be warned

but at the beginning of main() set it up with


	auto audio = new AudioPcmOutThread();
	audio.start();
	scope(exit) {
		audio.stop();
		audio.join();
	}


and then when you want it to make sounds, call its functions like

     audio.beep();

or

     audio.playOgg("my-file.ogg");

you can convert things like wav and mp3 into the ogg format with 
various tools of the internet.



that's about all it does.

Thank you sooo much. Now it works. That is pretty much what I was 
looking for.

Thanks. Now, I would like to know if I could just use it like 
this instead:

import arsd.simpleaudio;

void main()
{
     AudioPcmOutThread audio = new AudioPcmOutThread;
     audio.start;
     audio.playOgg("shock.ogg");
     audio.join;
     audio.stop;
}

What happens if an exception is thrown in the middle of your 
function? It shouldn't really matter (at least not with the newer 
versions) since it will automatically exit the audio thread when 
the main thread exits, but still there's definitely no benefit to 
writing it without the scope guard.

I'm very minimalistic, I hate unnecessary complexity, I believe 
that simple is better than complex so I always try to use the 
least syntax and lines of code when I'm making a program. That is 
why I don't like the scope guard. Could I simply add the lines 
`audio.stop(); audio.join();` to the very end of main()?

Are you sure it is like this:
audio.stop();
audio.join();
and not like this:
audio.join();
audio.stop();
?

Alright, thanks. So let me see if I get this straight, .stop() 
will stop the thread and then .join() will return. But what 
exactly does .join() return?

More specifically, stop tells the audio output to stop. It 
finishes what it is doing and then exits. At this point, the 
thread terminates.

join() waits for the thread to finish terminating (which it won't 
do if you don't tell it to stop *first*) and then cleans it up. 
join will return any exception/error it happened to throw while 
ending.

ahh, okay, thanks. Now, one last question, if stop() actually 
makes the output, not the thread, stop, then start() makes the 
output, not the thread, begin?

It does both. start is from the base class Thread, it starts it 
which immediately opens the audio device and can feed stuff when 
it is necessary.

Thanks Adam. That worked on Windows, but now that I have switched 
to Linux Mint it is throwing this:
arsd.simpleaudio.AlsaException arsd/simpleaudio.d(1170): params

Your system probably uses PulseAudio which I don't like, so I 
don't support it in my code.

It *might* work to run `pasuspender -- ./your_program_here` but I 
don't know.

I can check more tomorrow.

That unfortunately didn't work. I would be very grateful if you 
could find out a way around it and tell me.

the work you do with your library, I have been using it for 
everything, I'm now training a neural network using your library.

Hi Adam, sorry to bother you, but I'm having a problem with 
simpleaudio.d. This problem was happening on Windows too. When I 
play a sound the program never ends, the terminal continues to 
run the program and I have to end it manually. Any ideas what 
could be causing this? I am using it just as you had instructed.

That happens if you don't call .stop() and .join() in order at 
the right time.

Did you use the scope(exit) like I said?

Thanks for the help.
I did use the scope. Here is my code:
         AudioPcmOutThread audio = new AudioPcmOutThread();
         audio.start();
         scope (exit)
         {
             audio.stop();
             audio.join();
         }
         audio.playOgg("bell.ogg");
The problem persists.

I recommend SoLoud - bindings are available here 
http://code.dlang.org/packages/bindbc-soloud . It's more powerful 
than simpleaudio, supports multiple formats, 3D audio, etc.

heh. not hard to be better than my method list:

http://dpldocs.info/experimental-docs/arsd.simpleaudio.AudioPcmOutThread.html#members

beep
boop
blip
noise
playOgg

it is meant to be something more like an Atari 2600 than a modern 
movie theater :)
