Any performance issues with creating multiple addAudioSprite calls?

In my game I’m using around 60-70 sounds, with maybe a dozen loops in amongst them. As such I thought it would make sense to use an AudioSprite rather than loading dozens of individual files.

Creating the AudioSprite and the JSON is fine, but I’m now discovering you can’t do things like fade the sounds or play multiple markers at once. The only way you can do this, as far as I can determine, is to use multiple addAudioSprite calls and handle them each separately:

	this.musicBG = this.sound.addAudioSprite('sfx', { volume: 0 });
	this.musicBG.play('bg_music', { loop: true });

	// I can now tween the audiosprite instance

	this.tweens.add({
		targets:  this.musicBG,
		volume:   1,
		duration: 1000
	});

	//	Create another audio sprite to play sound effects without interrupting the BG music

	this.soundFX = this.sound.addAudioSprite('sfx');
	this.soundFX.play('yowza');

My question is: is this the way to do it? Is there any performance impact in creating multiple AudioSprites in this way? Almost all of my game sprites are separate prefabs, so they’ll have their own addAudioSprite/playAudioSprite calls. I don’t anticipate there being many sounds playing at once - maybe 3-4 at most - but don’t want to cause unnecessary memory issues.

That is the way to do it, but I’m not sure of the memory consequences. You could still use more than one sprite file, e.g. split up the music and sound effects.

Thanks Samme. I was thinking of exactly the same thing, but having tested it with a few concurrent loops and sounds, I think it’ll work fine as-is.
