PyEDFlib -EDF/BDF Toolbox in Python

PyEDFlib is a free Open Source wavelet toolbox for reading / writing EDF/EDF+/BDF files.

import pyedflib
import numpy as np
import os

file_name = os.path.join(pyedflib.util.test_data_path(),
                         'test_generator.edf')
f = pyedflib.EdfReader(file_name)
n = f.signals_in_file
signal_labels = f.getSignalLabels()
sigbufs = np.zeros((n, f.getNSamples()[0]))
for i in np.arange(n):
    sigbufs[i, :] = f.readSignal(i)

Description

PyEDFlib is a Python library to read/write EDF/EDF+/BDF files based on EDFlib.

EDF stands for European Data Format, a data format for EEG data, first published in 1992. In 2003, an improved version of the file protocol named EDF+ has been published.

The definition of the EDF/EDF+ format can be found under edfplus.info.

The EDF/EDF+ format saves all data with 16 Bit. A version of the format which saves all data with 24 Bit, called BDF, was introduced by the company BioSemi.

The PyEDFlib Python toolbox is a fork of the python-edf toolbox from Christopher Lee-Messer. and uses the EDFlib from Teunis van Beelen.
