The plugin keeps the unpredictable, characterful sound that made the first version popular while adding full AUv3 compatibility. It works as an effect in hosts like Logic Pro for iPad, AUM, or GarageBand, allowing you to stack multiple instances across tracks for rich, textured delays. The warbly tape-style echoes, pitch instability, and lo-fi degradation remain intact. From the same developer behind Osculatrix and FrobulatorAU, NebulizerAU continues the pattern of free, no-tracking experimental AUv3 tools for iOS.

NebulizerAU works well for adding movement and vintage character to pads, vocals, guitars, or full mixes. The simple interface gives you the essential controls so you can dial in the right amount of chaos quickly, while the DSP delivers the same wayward, musical results as the original standalone app.

Key features include:

  • Classic warbly, malfunctioning tape delay sound
  • Full AUv3 effect plugin support for use in any compatible host
  • Lo-fi degradation, pitch instability, and characterful echoes
  • Simple, focused interface for quick sound shaping
  • Low CPU usage for stacking multiple instances

App price: Free.
No in-app purchases.
