The CPU Cut button in the header bar reduces FOAM’s processing load by scaling density and bubble size by 0.75x, resulting in fewer simultaneous bubbles.

​
When to Use

  • Running on a laptop or low-spec machine
  • Using multiple instances of FOAM in a session
  • Experiencing audio dropouts or glitches

​
How It Works

CPU Cut reduces the bubble count without changing the fundamental character of your sound. The tonal quality and spatial properties remain the same — you just get fewer simultaneous bubbles.

​
Other CPU Tips

  • Reduce Rate — fewer bubbles per second means less CPU
  • Reduce Topology — foam physics simulation is CPU-intensive
  • Lower Cascade — chain reactions multiply bubble count exponentially
