PyEDFlib -EDF/BDF Toolbox in Python

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

>>> import pyedflib
>>> import numpy as np
>>> f = pyedflib.EdfReader("data/test_generator.edf")
>>> 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)


pyEDFlib is a python library to read/write EDF+/BDF+ files based on EDFlib.

EDF means [European Data Format](http://www.edfplus.info/) and was firstly published [1992](http://www.sciencedirect.com/science/article/pii/0013469492900097). In 2003, an improved version of the file protokoll named EDF+ has been published and can be found [here](http://www.sciencedirect.com/science/article/pii/0013469492900097).

The EDF/EDF+ format saves all data with 16 Bit. A version which saves all data with 24 Bit, was introduces by the compony [BioSemi](http://www.biosemi.com/faq/file_format.htm).

The definition of the EDF/EDF+/BDF/BDF+ format can be found under [edfplus.info](http://www.edfplus.info/).

This python toolbox is a fork of the [toolbox from Christopher Lee-Messer](https://bitbucket.org/cleemesser/python-edf/) and uses the [EDFlib](http://www.teuniz.net/edflib/) from Teunis van Beelen. The EDFlib is able to read and write EDF/EDF+/BDF/BDF+ files.
