FLAC - numcodecs implementation

Numcodecs wrapper to the FLAC audio codec using pyFLAC.

This implementation enables one to use FLAC as a compressor in Zarr.

Installation

Install via pip:

pip install flac-numcodecs

Or from sources:

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

Usage

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

from flac_numcodecs import Flac

data = ... # any numpy array

# instantiate Flac compressor
flac_compressor = Flac(level=5)

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

data_read = z[:]

Available **kwargs can be browsed with: Flac?

NOTE: In order to reload in zarr an array saved with the Flac, you just need to have the flac_numcodecs package installed.
