In Arduino for the
A simple Arduino-based oscilloscope program, developed to record and display sound input, but should also display a biopotential input from the sound card of any computer. Limited analysis functionality.

ECG Viewer – developed by John Ramshur
Open Source ECG display and analysis software. This software does not record ECGs but will open previously recorded files (in a couple of different formats) for sophisticated analysis. Developed in Matlab, but can be used as a standalone program. Well-documented.

Spikehound – developed by Gus Lott (one of gPrime’s creators)
Open Source software developed to record and analyze invertebrate extracellular signals through the sound card of a Windows computer, but should also effectively record human EMGs and ECGs. The analysis routines are very sophisticated.

BioSemi offers for download an Open Source biosignal display and analysis software, ActiView, that is based in LabView, but available as standalone versions for Windows, Mac and Linux. I have not tried the software and do not know how useable it is for non-BioSemi hardware. LabView users should be able to adapt the program for non-proprietary uses.

BrainBay – developed by Christoph Veigl
Open Source software developed to display in real time, save, and analyze specifically EEG signals, but also other human biopotentials. A standalone Windows application. This is part of the OpenEEG Project, and is very comprehensive, well-documented software. A detailed User Manual is available and also a manual with instructions for developers who would like to modify the software.

freeecg
Very basic oscilloscope software developed to display an ECG signal that arrives via the computer sound port. Very limited analysis capability. Windows-based. A linked site includes plans and instructions for building a very inexpensive ECG amplifier.
