AcqKnowledge is a flexible, feature-rich software platform for physiological data acquisition, stimulation, and signal analysis. Designed to support a wide range of research applications, it provides an intuitive user experience for recording, visualizing, and analyzing physiological signals in real-time or post-acquisition—without requiring any programming.
Whether you're working online or offline, AcqKnowledge offers a wide range of tools and transformations. Apply filters and analysis settings in real time, or take advantage of comprehensive post-acquisition analysis features. Switch between multiple display formats—Chart, Scope, X/Y, Overlapped Segments, Histogram, or FFT—at the click of an icon.
Record, display, and analyze physiological signals with real-time feedback and complete control. AcqKnowledge supports analog, digital, and calculation channels, letting you configure complex acquisition protocols with ease. Use preconfigured presets for common parameters like ECG, respiration rate, blood pressure, and heart rate variability—or create custom channel setups tailored to your experiment. Visualize data in multiple formats, including chart, scope, X/Y plots, histograms, FFT, and overlapped segment views—switch between them instantly with one click.
Customize your workspace fully: change waveform colors, grid scaling, background styles, axis divisions, and toolbar layouts. Save your preferred setups as presets for future use, including customized ECG grids or frequently used analysis buttons. Graph windows allow multi-view setups to inspect the same dataset from different perspectives.
Simultaneously record from multiple BIOPAC hardware systems—combine MP200, MP36R, B-Alert, and more within one session. On Windows, take advantage of integrated video sync: link data recordings to webcam or camera video feeds for synchronized playback. The data and video stay locked together, making it easy to navigate either file and jump to the corresponding moment in the other.
AcqKnowledge offers comprehensive stimulus delivery features. Configure single pulses, trains, or arbitrary waveforms for constant current or constant voltage stimulation. Integrate with stimulus presentation tools such as E-Prime, SuperLab, and Presentation, or sync digital events from virtual reality environments. Trigger events, categorize them, and link them directly to signal analysis workflows.
The software is also compatible with third-party tools and data formats. Import and export to MATLAB, Excel, text, Noldus Observer XT, SMI BeGaze, and more—ensuring smooth collaboration and cross-platform data sharing.
Speed up your analysis with powerful, automated routines for a wide range of signals, including ECG (with HRV and QRS detection), EEG, EDA, EMG, respiration, RSA, and impedance cardiography (ICG). Use AcqKnowledge’s Focus Areas to isolate regions of interest within a recording and apply your analysis only to those segments. This is ideal for comparing conditions (e.g., baseline vs stimulus) or excluding noise and artifacts.
A broad suite of transformations and filters is available both during and after acquisition. Perform cycle detection, FFT, and spectral analyses on selected data regions. Use expression evaluation tools, create journal notes, and export findings to Excel or as 3D plots. Scale and rescale axes, annotate recordings, and extract data with precision.
From amplifier selection to final export, AcqKnowledge simplifies setup and speeds up workflows. Preconfigured channel templates minimize time spent configuring experiments. The software includes an in-depth user guide, step-by-step video tutorials, and a searchable knowledge base.
