Whenever I listen to this track, it feels like there is an additional sound applied to the singer's voice. The singer can sing very well, that's I know for sure, because I saw him live. By the way, in this track, there is an additional sound/feel used along with his singing; and that additional feel/sound makes the singing/voice more attractive and sharp. What is this technology/technique known as? Is this technology/technique applied by using only software or hardware or using both?
Listen from 0:18 to 0:57 ; 1:40 to 1:55 very attentively. I am Not talking about harmonization/echo here. I am talking about an extra layer of digital/computerized/artificial sound or something else which has been added in some/all parts of the track.
