Auto-harmonization relies on an inputted audio signal, which is analysed to detect a note’s pitch, before applying an instant harmony to the original note, by resampling the incoming audio.
This effect, which is a little bit like shining light into a prism to reveal the rainbow colours which make up white light (hence the name Prismizer), caught the ear of a number of artists, including Jacob Collier and Imogen Heap.
