使用SoundJs更改全局音量

Question

I'm creating an application in HTML5 using CreateJS. By starting with the part of sounds, using SoundJS, I have seen that has many limitations. The createjs.Sound object has the method of play() and stop() . But play() executes only a specific sound and stop() for all the sounds of the stage.

I wanted to know is if there is any way to define a global volume for all sounds and be able to go up or down at any time, although it sounds one or ten at a time.

I had initially thought the option to create a global variable and use it as a parameter of volume when playing a sound. My problem is that I use several classes in different files, and they all have independent sounds. They would need that variable out comprehensive beyond the classes and methods. I'm programming with typescript.

I can't use the master volumen for my problem. In the documentation, I can find: createjs.Sound.volume = 0.5;

But it changes all the global volume. I need to separe the music and the sound effects in two different volume options.

Answer 1

There is no way to do audio "groups" for volume, playback, or panning at this time. You would have to store off instances you want to control into arrays/groups, and then iterate those groups to set those values on each instance.

This could be a handy feature, so feel free to log an issue on GitHub .

Answer 2

I make my own solution. I created two global boolean variables. One for the music and the other for the sounds. When I want to reproduce a new sound, check if this variable is set to True.

It works fine for me.
