Helix World makes explorable scenes respond with matching spatial sound
Helix World lets you steer a generated scene from one image while it produces the next video and stereo soundtrack together, so turning the camera also turns the sound field. It runs at 24 frames per second on one NVIDIA H800, with each control input applied in roughly 1.3-second generation chunks. On the HelixBench spatial-acoustic test, it scores 41.8 versus 12.7 for EchoWM, the only other compared world model that generates sound.
