 - A `Sound` represents a distinct audio source, derived from an `AudioBuffer` or a URL string pointing to an audio file, with advanced filter management.
 - A `Playback` refers to the act of playing a `Sound`, with additional properties such as position in a 3D audio scene, gain-node for volume control, and methods for fading audio in and out.
 - A `Group` encapsulates multiple `Sound` instances to handle them as one entity, allowing for synchronous control of playback.
