A toolbox for biosignal processing written in Python.

🎙️ Announcements

🗒️ BioSPPy can now read EDF files directly! 
With the biosppy.storage module you can now load your EDF files!

🌀 New module for signal quality assessment 🌀
With the biosppy.quality module you can now evaluate the quality of your signals!
So far, the EDA and ECG quality are available, but more could be added soon. 

🫀 New module for heart rate variability (biosppy.signals.hrv)
🎊 New module for feature extraction (biosppy.features)

BioSPPy - Biosignal Processing in Python

The toolbox bundles together various signal processing and pattern recognition methods geared towards the analysis of biosignals.

Highlights:

• Support for various biosignals: ECG, EDA, EEG, EMG, PCG, PPG, Respiration, HRV
• Signal analysis primitives: filtering, frequency analysis
• Feature extraction: time, frequency, and non-linear domain
• Signal quality assessment
• Signal synthesizers
• Clustering
• Biometrics

Installation

Installation can be easily done with pip:

$ pip install biosppy

Alternatively, you can install the latest version from the GitHub repository:

$ pip install git+https://github.com/scientisst/BioSPPy.git

Simple Example

The code below loads an ECG signal from the examples folder, filters it, performs R-peak detection, and computes the instantaneous heart rate.

from biosppy import storage
from biosppy.signals import ecg

# load raw ECG signal
signal, mdata = storage.load_txt('./examples/ecg.txt')

# process it and plot
out = ecg.ecg(signal=signal, sampling_rate=1000., show=True)

This should produce a plot similar to the one below.
