Using a Single Speaker to Play Multiple Sounds

Tehgates64 · January 6, 2025, 10:49am

Hi,

I’m wondering if it is possible to play multiple sounds from a single speaker. The reason is I have characters speaking several lines of dialog, which means I would need dozens of speakers parented the characters, which would be cumbersome. I could use several Play Sound nodes, but the sound wouldn’t be location specific (louder when closer, etc). Does anyone have any ideas on how the get around this?

Kind regards

Hi,

Well playSoundNode was modified to allow exactly that.

You could try it with a haxe trait and replace the sound file, it should be possible I guess:

github.com

armory3d/iron/blob/main/Sources/iron/object/SpeakerObject.hx

package iron.object;

import kha.FastFloat;
import kha.audio1.AudioChannel;
import iron.data.Data;
import iron.data.SceneFormat;
import iron.math.Vec4;
import iron.system.Audio;

class SpeakerObject extends Object {

#if arm_audio

	public var data: TSpeakerData;
	public var paused(default, null) = false;
	public var sound(default, null): kha.Sound = null;
	public var channels(default, null): Array<AudioChannel> = [];
	public var volume(default, null) : FastFloat;

	public function new(data: TSpeakerData) {

This file has been truncated. show original

There is also another sound library called aura that extends speakers and works with armory3d:

Good luck

yeah it works… well maybe it would be best to make the same modification the playSoundNode has.

Also there is no way to change volume with a node…

Hey Lapiz,

Thanks for getting back to me. Yeah if I can have a trait that switches out the speaker sound file and then plays it that would be ideal. Then I could make this functionality a custom node. Do you know where the modified playSoundNode is or what the Haxe trait might look like?

The Aura engine looks useful, but I don’t really understand how to use it - I’m not much of a programmer.

Regards

Youre in luck. Its already been merged.You can update this files in your armory folders or wait for the next month release.

github.com/armory3d/armory

SpeakerNodes: setSound and setVolume

armory3d:main ← t3du:SpeakerNodes

t3du

These functions allow to modify both sound and volume, so the same speaker can b…e reused with a different sound and volume. So good now iron is included in the same repo! ![image](https://github.com/user-attachments/assets/6b0f6a5f-ed48-498f-9ef6-f6b8ea36a948) [Using a Single Speaker to Play Multiple Sounds](https://forums.armory3d.org/t/using-a-single-speaker-to-play-multiple-sounds/5868/3)
