FlxSoundFilters

Adds easy support for OpenAL filters and effects on FlxSounds.

Only works when using OpenAL! (so no HTML or Flash I think)

Not all OpenAL effects have been implemented yet!

Installation

• Run this command to install the haxelib

haxelib git flxsoundfilters https://github.com/TheZoroForce240/FlxSoundFilters

• Add "flxsoundfilters" to the project.xml

<haxelib name="flxsoundfilters" />

Example Usage

Using FlxFilteredSound (auto updates and stores filter)

var sound = new FlxFilteredSound();
sound.loadEmbedded("flixel/sounds/flixel.ogg");
FlxG.sound.list.add(sound);
FlxG.sound.defaultSoundGroup.add(sound);
sound.play();

sound.filter = new FlxSoundFilter();
sound.filter.filterType = FlxSoundFilterType.LOWPASS;
sound.filter.gainHF = 0.2;

Using regular FlxSound

var sound:FlxSound;
var filter:FlxSoundFilter;

function create()
{
    super.create();
    sound = FlxG.sound.play("assets/music/test.ogg");

    filter = new FlxSoundFilter();
    filter.filterType = FlxSoundFilterType.BANDPASS;
    filter.gainLF = 0.05;
    add(filter); //add so the filter will be destroyed automatically by the state (or destroy manually when not needed)
}

function update(elapsed:Float)
{
    super.update(elapsed);
    if (sound != null && sound.playing)
    {
         filter.applyFilter(sound);
    }
}

Adding an effect to a filter

var reverb = new FlxSoundReverbEffect();
sound.filter.addEffect(reverb);
reverb.decayTime = 3.5;
