LFP codec — lossy compression of local-field-potential recordings via adaptive SVD and wavelet-packet thresholding

lfpack — LFP codec for Neuropixels recordings

IBL Brain-Wide Map LFP dataset — 699 recordings, 384 channels, session-clock aligned. How to access →

Lossy codec for local-field-potential (LFP) recordings from Neuropixels probes. Achieves >100× compression with median RMSE < 25 µV via an 8-stage pipeline (bad-channel detection → dephasing → highpass → interpolation → CAR → decimation → Cadzow → adaptive SVD + wavelet-packet thresholding).

pip install lfpack
