Pip Abstractions is here: http://forum.pdpatchrepo.info/topic/8112/game-audio-designer-patches-pip-abs...
You don't need libpd for doing this. Unity built-in audio will do that
just fine (no needs to buy anything from the Asset Store):
[RequireComponent(typeof(AudioSource))] <- drag your sample on this component
public class ExampleClass : MonoBehaviour { void Start() { audio.Play(); } }
Libpd and Unity is mostly useful for generative music or fx that are
not part of Unity.
