Heartbeating sync'ed with dirtymetal pulsation for horrific effect

Took the heartbeat in https://freesound.org/people/PISEWO78/sounds/790012/ and synchronized with a different pitch of itself, resulting, in my view, in an horrific effect.

___
#technical specificities:
in audacity:
1. duplicated (new stereo track, copy the original)
2. the doubled version got: effect > pitch and tempo > change pitch > frequency > percent change > 117.505
3. doubled track 0.269 seconds ahead.

to not clip: volume of the original: -2.5 dB; volume of the doubled: -8 dB, manually lowered volume of it (I think -4dB) from the sixth beat.
