I honestly don't know what to call this effect because i had no idea what is it called. This was a bit similar to that hallelujah effect though. Feel free to use it. Created in 3ml editor and edited it in audacity.
The gong sound comes from a 32" paiste brilliant gong played by jens zygar in the former red house studio in gelsenkirchen recorded by christian wagner.
Took a violin bow to a chinese guzheng and the results were pretty great. Good for ambience, drones and creepy stuff. Recorded with blue spark and blue bluebird condenser mics through a scarlett 6i6 interface. Uncut with a small glue compressor to minimize spikes.
