PIXI Sound Filters

[TR-i]

Does anyone have some example code on how to implement PIXI sound filters? Tried parsing the code on the example page but it's pretty obtuse.

Is your question about how to create a new Filter Class, or how to bind an existing Filter Instance to an existing SoundInstance?

Are you wanting to run filters on mobile devices during intensive gameplay?

Just want to experiment with the built-in filters.

I understand the goal but I do not understand the problem.

Have you created a SoundInstance?  Have you created a Filter?  Are you aware of the "filters" (array) member of the SoundInstance?  If so push the created Filter instance into that array (or create the array).  Done.

Think of it like adding a Filter to a DisplayObject.

All I know is, this throws an error:

const sound = new PIXI.sound.Sound.from('data:audio/mp3;base64,' + audiodata);
sound.filters = [new filters.TelephoneFilter()];

As does this:

const sound = new PIXI.sound.Sound.from('data:audio/mp3;base64,' + audiodata);
sound.sound.filters = [new filters.TelephoneFilter()];

Option 1.  What's the error?  (F12, console message).

Try the full package reference ...

const sound = new PIXI.sound.Sound.from('data:audio/mp3;base64,' + audiodata);
sound.filters = [new PIXI.sound.filters.TelephoneFilter()];

Too much haste

[TR-i]

sound.filters = [new PIXI.sound.filter.TelephoneFilter()];

Throws an error.

sound.filters = [new PIXI.sound.filters.TelephoneFilter()];

Does not.

However, there seems to be no change in the sound after adding the filter. Tried Distortion and Reverb filters- no difference.

Sorry that was my bad on the typo, too much haste on my part!  Yes, package name is PIXI.sound.filters.  I have corrected in original post to avoid errors propagating to others.

Sound.from returns Sound.  Sound has member "filters" which is a passthru to this.media.filters.  I can see nothing specifically wrong with that code, so some debugging is needed - check whether WebAudio is being used perhaps?
