Devices for the measurement of signals use different data formats to store the data on disk.
libRASCH provides a common interface to access such signals, regardless in which format they are stored. The library is written in C and is available for

• Windows
• Linux

libRASCH provides additional interfaces for

• Perl
• Python
• Matlab
• Octave (only for the Linux version)
• SciLab (at the moment only for the Linux version)

• C++ (object-oriented interface)
• Java
• R

libRASCH is published under the GNU Lesser General Public License. On this page you will find more about the license.

Up to now the main focus of libRASCH is to handle biological signals (e.g. ECG, eeg, blood pressure) but the design of the library allows to handle any kind of signals.

For downloading libRASCH, go to this page. An overview of the design of libRASCH can be found here.

At the moment the audience for libRASCH are programmers. In the future it is planned to provide tools and programs (based on libRASCH) which allows the average users to access and process signals through a graphical user interface.

If you have any questions or comments about libRASCH, please send an email to Raphael Schneider or subscribe the libRASCH mailing list.
