EDFbrowser : View EDF and BDF Files on Windows

In the medical field, some instruments record the electrical signals when plotted against the time. Such instruments include EEG (electroencephalogram for recording brain activity), ECG (electrocardiogram for recording heart activity), EMG (electromyogram for recording muscle activity) and more. The data recorded by these devices is stored in EDF and BDF files. Now you can view EDF and BDF files on your Windows PC with the help of EDFbrowser.

EDFbrowser supports EDF, EDF+, BDF, BDF+ file formats. These files are all used to record data against the time. When you open these files with EDFbrowser, you are going to see a long graph of the electrical activity on the y-axis and time on the x-axis.

Of all the formats supported, EDF is the oldest and stores the data n 16 bit format. The BDF file format is similar to the EDF file format except that it stores the data in 24-bit format which allows for more information to be stored. EDFbrowser comes with a converted that can convert data from many different devices stored in their own proprietary formats into EDF or EDF+ formats. According to the developer, EDFbrowser sets the gold standard for EDF file format.


EDFbrowser can combine several EDF files and join them into a large EDF file. You can select part of a file and export it to a smaller EDF file, image file or a PDF file. The file can be printed on a printer that is connected to your Windows PC. It can also stream the data directly from a monitoring device (such as EEG) provided that an interface is available.

EDFbrowser offers an online manual and sample EDF file so that the users can fully test this software without first using it with their own EDF files.

EDFbrowser is available for Windows and Linux. It is source code is also available and it can also be compiled for the macOS according to the developer.
