Hi!

I am building an audiogame based on Allegro, but I encounter some problems during the process. As I've said before, I'm an absolute beginner, so excuse me for asking this stupid things.

I'd like to have multiple versions of the same sound playing, which I can control seperately. The last is possible with Voice Control, but I need to specify a voice so I can adjust it.
Now I'm trying to make a function like this:
place_objet(x_position, y_position, ID);
The ID will name the voice where the sound is playing, but these are automatically asigned. Thus I can't do things like:
asigned. Thus I can't do things like:
place_objet(20, 30, 1); // Object #1
place_objet(50, 90, 2); // Object #2

So, I have to obtain the voice where the sound is playing with allocate_voice, but at the same time I already need this voicenumber, because it should be my ID.

I know this is not very common, but does someone get my point and maybe can provide some help?

I just don't know how to do this in another way.

My problem is that I want to make multiple objects at the same time. And if Allegro gives me a voicenumber, and I store that, and then build up a new object (from the same function) it'll override the original one, isn't it?

Or just use the value returned by play_sample().

Better to allow only 1 instance of a sound to play at once.

The more sounds you play the lower the sound quality. If you get too many playing at once it will sound awful and you lose the point of playing sounds in the first place.

Also remember the old saying KISS, Keep It Simple, Stupid.

You don't select the voices number yourself... If you have any sound program running (Winamp), you could have ANY voices busy and unavailable to Allegro - and it probably won't be as simple as voices 0 and 1.
You'll have to uniquely identify your objects, without relying on the voices numbers.
Something like:

edit: argh, I just saw the word "classes" in your post.. I should have made it C++ instead of C++-like.

There is a design flaw (IMHO) in Allegro's sound handling which makes it difficult to play a sample using a specific voice. You have to let Allegro find a voice and then manipulate that voice channel.

By the way, am I right that adjust_sample(*spl); adjusts the first one that it finds. So, if you make two samples, the first one is always adjusted, even if you call adjust_sample() multiple times?

If I play one sound with my own created class all is fine, but when I try to play two sounds, they're played at the far left side of the stereofield.
And now I wonder why that's happening. I thought that it maybe had something to do with the play_sample-function. But after reading this I guess that it is a problem in my class or something.

The pan variable is currently declared in the function itself (which is declared in the class), but that seems to trouble.

I know that this stuff isn't really common, although I hope to find a good solution quite soon.

I don't know if someone is able to understand it, but here we go...

The class:

class rock {
public:
       
       int rock_x;
       int rock_y;
       rock();
       ~rock();
       void adjust_rock(void);
};

• The variables that are not declared in this piece of code are declared globally.

• I duplicate the code from the main-function to obtain a new sound (all in one loop).

One last question: Is it true that Allegro adjusts the volume when you pan a sound, and if so, can I prevent Allegro from doing that?

I meant: are there differences between the way adjust_sample and voice_set_pan works?

Some programs/mixers/whatever boost the volume of the left channel when you pan to the left. But others just cut down the volume of the right side (which is better in my opinion).

Edit: I found it! I needed set_volume_per_voice().
