Despite the final mix being complex, as sound design was often competing with the music in the mix, we still created a detailed and absorbing sound design track. We tackled Planet Unknown in stages creating separate audio projects for ambience, rocks, impacts, robots driving, robots moving, vocalisations and music.
To create unique and interesting fire sounds for the meteors we recorded a fire poi artist named Natatie Bibi. The sounds were recorded relatively simply using an H5 Zoom recorder. We then created an instrument in Izotope Iris using different layers of the cyclical fire sounds. When played on a midi keyboard the results were dense and the obvious cyclical nature lost. These mutations were used throughout for the meteor fire effects.
