Use this original version as the reference cut in an edit, before any later version, so listeners hear the first form first. No companion sound is documented for it in the supplied facts, so do not add a pairing on the basis of the title alone.
Sobre este som
This is Versão 1.0, an 18-second clip listed as the original version of the sound, with no voice, effect, character or source work documented in the supplied facts. No feeling, mood or origin can be tied to it from those facts alone, so it should be heard as the first version on its own terms, without assuming a scene, speaker or story behind it.
