High-density electrophysiology probes have opened new possibilities for systems neuroscience in human and non-human animals, but probe motion poses a challenge for downstream analyses, particularly in human recordings. We improve on the state of the art for tracking this drift with four major contributions. First, we extend previous decentralized methods to use multiband information, leveraging the local field potential (LFP) and current source density (CSD) as well as spikes. Second, we show that the CSD-based approach enables subsecond drift tracking. Third, we introduce an efficient online
