RECORD, MONITOR AND REVIEW BIOSIGNALS IN ONE WORKFLOW
g.Recorder is a dedicated biosignal acquisition, recording and review environment for neuroscience research. It enables researchers to configure g.tec amplifiers, acquire and visualize high-resolution biosignals in real time, monitor signal quality and electrode impedance, record precise event and trigger information, and review recordings immediately after an experiment.
g.Recorder supports EEG, ECoG, ECG, EMG, EOG and other biosignals from g.tec amplifiers, including g.HIamp, g.USBamp and g.Nautilus. Recording workflows can include multiple biosignals, digital triggers, experimental events and, with g.Recorder Professional, synchronized video. Wireless EEG recordings can be acquired with g.Nautilus, while high-speed acquisition supports applications requiring high temporal resolution, including TMS-EEG and evoked-potential experiments.
Researchers can calculate and visualize evoked potentials during or after recording, replay acquired data, monitor signal quality and impedance, and store recordings in HDF5 format for subsequent analysis in g.BSanalyze or MATLAB. Paradigm Presenter and external interfaces can be used to synchronize experimental stimuli and triggers with the recorded biosignals.
From amplifier configuration and signal-quality checks to synchronized acquisition, recording, review and analysis-ready data, g.Recorder provides a complete workflow for reliable biosignal recording in neuroscience, BCI, TMS-EEG, evoked-potential, sleep and multimodal research.

HIGH-SPEED TMS-EEG RECORDING
g.Recorder supports high-speed EEG acquisition for experiments combining transcranial magnetic stimulation (TMS) with EEG. EEG channels can be acquired at high sampling rates without applying recording filters, while the exact timing of the TMS pulse can be recorded through the amplifier’s TTL trigger input.
After acquisition, recordings can be reviewed and processed for evoked potentials and TMS-related artefact correction. This workflow supports experiments investigating TMS-evoked responses, motor cortical stimulation and other time-critical neurophysiological effects.
REAL-TIME EVOKED POTENTIAL ANALYSIS
g.Recorder provides real-time evoked-potential visualization for time-locked biosignal responses. Researchers can define pre-trigger and post-trigger intervals, average responses across trials, and visualize evoked potentials for individual channels.
Multiple triggers can be analyzed simultaneously, including target and non-target events. Statistical differences between responses can be calculated and highlighted, making g.Recorder suitable for ERP, EP, P300 and other event-related neuroscience experiments.
MULTIMODAL BIOSIGNAL RECORDING
g.Recorder can combine multiple biosignal types within a single acquisition workflow. Depending on the connected hardware, researchers can record EEG, ECoG, ECG, EMG, EOG and additional sensor data while synchronizing triggers and experimental events.
This makes g.Recorder suitable for multimodal neuroscience studies where several physiological signals need to be acquired, monitored and stored together for subsequent analysis.
FROM RAW BIOSIGNALS TO ANALYSIS-READY DATA
g.Recorder provides real-time visualization and recording of high-resolution biosignals, with acquisition rates up to 38.4 kHz depending on the connected amplifier and configuration. Triggers, event markers and region markers can be recorded together with the biosignal data.
Recordings are stored in HDF5 format for subsequent analysis in g.BSanalyze or MATLAB. The Montage Creator allows researchers to define electrode positions and, where supported, measure electrode locations for spatial analysis and visualization.

SYNCHRONIZE EXPERIMENTS AND BIOSIGNAL RECORDINGS
g.Recorder integrates with Paradigm Presenter to synchronize experimental stimuli, triggers and biosignal acquisition. Researchers can create and run custom experimental paradigms while recording the resulting biosignals and event markers in the same workflow.
This enables time-locked experiments such as evoked potentials and BCI paradigms without requiring separate stimulus-presentation software. Paradigm Presenter communicates with g.Recorder via UDP to coordinate experimental events and recorded data.
PART OF THE G.TEC SOFTWARE ECOSYSTEM
g.Recorder is part of the g.tec Suite 2024, which combines g.NEEDaccess, g.HIsys, g.BSanalyze and g.Recorder in one software environment. The g.tec Suite 2024 simplifies software installation, updates and compatibility across the g.tec ecosystem.
Researchers can use g.Recorder for biosignal acquisition, recording and review, g.HIsys for real-time signal processing and BCI or closed-loop applications, and g.BSanalyze for advanced offline analysis. g.NEEDaccess provides access to the underlying APIs and interfaces for integrating g.tec hardware and software into custom research workflows.
