# Instrument IX, Noise Drone Usable for creating atmosphere, as well as creating interesting risers and sources of noise for percussion. Any source of unpitched sound can be a noise drone, if it can be slowly modulated in many different directions. > [!cite] Lore > ![[9-agonys-paralyze.png]] > Agony's Paralyze (art by Dead Carcosa) ## Noise Drone From [[Signal Music, Atmosphere]]. This uses a bank of 8 bandpass filters, and uses `[rand~]` sources to slowly modulate the frequency, resonance, and gain, of each of the 8 bands slowly. This can create wind and thunder sounds. > [!example] > ![[image-106.png]] > A noise drone patch.
