Shruti Drone is currently a prototype that makes it possible to create sustained sounds using additive synthesis. These sounds are reminiscent of traditional shruti boxes but with a modern twist. With a wide range of bass sounds to harmonium-like tones, organ sounds, and synthesizers, Shruti Drone offers a diverse sonic palette. Furthermore, the process is characterized by numerous modulation options that allow users to shape the sounds according to their preferences and create unique soundscapes.
