This Open Ephys plugin allows the user to mix, weight, and apply a rolling average to bandwidths of interest on a single channel. Its output can be thought of as a real-time power signal for waveforms with complex but well-specified frequency components. It can be paired with the crossing detector plugin to trigger events when the output power reaches a threshold to trigger events based on waveforms of interest.
It was developed to detect absence seizures in mice in real time based on their spectral properties as described in Sorokin et al, 2016.
The Open Ephys team has added the multi-band integrator to its collection of supported plugins! See their documentation to install and use with the latest version of Open Ephys (0.5.3 and later): https://open-ephys.github.io/gui-docs/User-Manual/Plugins/Multiband-Integrator.html

The example data set contains mouse EEG recordings and annotations for seizure start/end times for plugin testing and future development. See ExampleData/ExampleDataNotes.txt for details
This plugin and install procedure has only been built and tested on Windows. It depends on the Dsp library and a subset of the Boost libraries, making it tricky to install. Installing the latest version of Open Ephys and its built-in plugin installer here instead is highly recommended. To install for Open Ephys version 0.4.5, try the following:
Copy multi-band-integrator/Source/ to plugin-GUI/Source/Plugins/MultiBandIntegrator.
Copy multi-band-integrator/Builds/VisualStudio2013/MultiBandIntegrator to plugin-GUI/Builds/VisualStudio2019/Plugins/MultiBandIntegrator.
In Visual Studio 2019, open the Plugins.sln solution and add the MultiBandIntegrator project (File -> Add -> Existing Project... and select Builds/VisualStudio2013/Plugins/MultiBandIntegrator/MultiBandIntegrator.vcxproj)
To get Boost to work:
Properties -> Configuration Properties -> C/C++ -> General, click drop-down for Additional Include Directories and select <Edit...>\plugin-GUI\Source\Plugins\MultiBandIntegrator\boostAcc to the upper window and click "ok" to add it as an additional include directoryTo get DspLib to work:
Build Dependencies -> Project Dependencies... and check that DspLib has a check next to itBuild Dependencies -> Project Order... and check that MultiBandIntegrator is lower than DspLib in the build orderProperties -> Configuration Properties -> Linker -> Input, click drop-down menu for Additional Dependencies and select <Edit...>DspLib.Lib to upper windowBuild the plugin
