pip install wavpack-numcodecs

Or from sources:

git clone https://github.com/AllenNeuralDynamics/wavpack-numcodecs.git
cd wavpack_numcodecs
pip install .

Usage

This is a simple example on how to use the WavPackCodec with zarr:

from wavpack_numcodecs import WavPack

data = ... # any numpy array

# instantiate WavPack compressor
wv_compressor = WavPack(level=2, bps=None)

z = zarr.array(data, compressor=wv_compressor)

data_read = z[:]
