I am a total outsider not well-versed in the Buddhist tradition, and apologize in advance if some of the terms/names I'll write are placed out of context or misused.
To cut the story short, I am looking for a transcription (and possibly translation into English) of a certain Tantric overtone singing (Rgyud Skad) fragment, used as a sound effect at the end of each level in Painkiller 2004 videogame.
According to my research, I believe it to be a sample from Yamāntaka mantra as performed by Gyütö Monks on this album, 4th track, starting at 0:32 time mark.
I tried to make sense of the chanting by reading Meditation on Vajrabhairava and attempting to "sync" the text by looking at the places where performers play the bell — obviously, I have little to no idea of what I am doing and that didn't ring any bells (pun intended) :)
