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.
This is a "happy birthday to you" rendition to celebrate the 15th freesound birthday (april 5th 2020). The sound has been made by researchers of the music technology group of universitat pompeu fabra (i. E. Where freesound happens!), and voctrolabs. The sound uses choir synthesis technology developed for the trompa eu project. This means that what you hear are not real singers but synthesized voices generated by a computer! the score adaptation for choir is based on a score published in the choral public domain library. Hope you enjoy it and. . . . Happy birthday dear freesound!.
These are recordings of a small female choir group i recorded for a college film back in 2012. Captured with a stereo mid side mic into pro tools at 96k for use with effects such as paul stretch. I uploaded the cleanest takes i got, room noise is there but isn't terrible.
