The official homepage describes BioSig as a GPL software library for biomedical signal processing, covering data acquisition, artifact processing, quality control, feature extraction, classification, modeling, data visualization, and many biosignal domains. BioSig grew as a family of related components: BioSig for Octave and Matlab, BioSig for C/C++, rtsBCI, BioProFeed, and BCIx. The projects page describes the C/C++ part as a library for reading and writing biosignal data formats and notes use in converters such as save2gdf, mexSLOAD, SigViewer, and Python bindings. ### Adoption history The official NEWS file records long-running adoption milestones: prominent SourceForge activity in 2006, Windows tools and many supported formats by 2008, Debian-related packaging work by 2012, Debian 10 inclusion for libbiosig/biosig-tools in 2019, Homebrew support in 2015 and 2018, PyPI availability from 2020, and Windows PyPI support in 2024. The input package metadata lists Homebrew, Debian, and Ubuntu package names, reflecting its role as a scientific format-conversion and signal-processing toolkit that is useful outside its original Matlab/Octave environment. ### How it is used Homebrew installs command-line tools such as `save2gdf`, `biosig2gdf`, `rec2bin`, `bin2rec`, and related converters. The project documentation points users to supported data formats, function references, mailing lists, bug reports, and the Git repository. BioSig is most often relevant when a biosignal data file must be read, converted, or normalized across EEG/ECG and related research formats, especially around GDF and EDF-like workflows. ### Why package nerds care BioSig matters to package nerds as a classic SourceForge-era scientific package that survived into modern package managers. It carries a large format-support surface, C/C++ libraries, Matlab/Octave roots, Python/R bindings, and CLI converters across decades of research computing. ### Timeline - 2000: BioSig SourceForge project created. - 2004: BIOSIG 0.60 and 0.65 releases noted; online help uploaded. - 2005: BioSig4C++, SigViewer, BioProFeed, rtsBCI, and biosig4octmat subprojects noted. - 2006: BioSig for Python started; SourceForge activity and ranking milestones noted. - 2012: Debian/Wheezy packaging work noted for libbiosig, biosig4c++ tools, mexSLOAD, and biosig4python. - 2019: libbiosig/biosig-tools included in Debian 10. - 2020: Homebrew formula availability and PyPI availability noted. - 2024: 64-bit Windows PyPI support noted. ### Related projects - BioSig is related to biosig4octmat, biosig4c++, rtsBCI, BioProFeed, BCIx, SigViewer, libbiosig, GDF, EDF/BDF-style biosignal formats, EEGLAB, Octave, Matlab, Python, and R bindings. ### Sources - - - - - - source_facts.executables - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Other Package-Manager Records - Debian apt - biosig-tools - 3.9.0-1: normalized package name match | Debian stable package indexes: biosig-tools from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | format conversion tools for biomedical data formats | https://biosig.sourceforge.io/ - Debian apt - libbiosig-dev - 3.9.0-1: normalized package name match | Debian stable package indexes: libbiosig-dev from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | I/O library for biomedical data - development files | https://biosig.sourceforge.io/ - Debian apt - libbiosig3 - 3.9.0-1: normalized package name match | Debian stable package indexes: libbiosig3 from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | I/O library for biomedical data - dynamic library | https://biosig.sourceforge.io/ - Debian apt - octave-biosig - 3.9.0-1: normalized package name match | Debian stable package indexes: octave-biosig from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Octave bindings for BioSig library | https://biosig.sourceforge.io/ - Debian apt - python3-biosig - 3.9.0-1: normalized package name match | Debian stable package indexes: python3-biosig from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Python3 bindings for BioSig library | https://biosig.sourceforge.io/ - Ubuntu apt - biosig-tools - 2.6.0-1ubuntu1: normalized package name match | Ubuntu 24.04 LTS package indexes: biosig-tools from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | format conversion tools for biomedical data formats | https://biosig.sourceforge.io/ - Ubuntu apt - libbiosig-dev - 2.6.0-1ubuntu1: normalized package name match | Ubuntu 24.04 LTS package indexes: libbiosig-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | I/O library for biomedical data - development files | https://biosig.sourceforge.io/ - Ubuntu apt - libbiosig3 - 2.6.0-1ubuntu1: normalized package name match | Ubuntu 24.04 LTS package indexes: libbiosig3 from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | I/O library for biomedical data - dynamic library | https://biosig.sourceforge.io/ - Ubuntu apt - octave-biosig - 2.6.0-1ubuntu1: normalized package name match | Ubuntu 24.04 LTS package indexes: octave-biosig from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Octave bindings for BioSig library | https://biosig.sourceforge.io/ - Ubuntu apt - python3-biosig - 2.6.0-1ubuntu1: normalized package name match | Ubuntu 24.04 LTS package indexes: python3-biosig from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Python3 bindings for BioSig library | https://biosig.sourceforge.io/ ## Combined YAML source View the package source record on GitHub.
