About ACQ files

An .ACQ file is primarily a proprietary data acquisition format created by AcqKnowledge software from Biopac Systems. These files store complex physiological data - such as ECG, EEG, and GSR signals - recorded via Biopac hardware for life science research. While highly efficient for storing multi-channel waveform data, the .ACQ format presents significant accessibility hurdles. It is a closed binary format, meaning it cannot be opened natively in standard analysis tools like Microsoft Excel or MATLAB without specific plugins or the original expensive software license. This proprietary lock-in makes sharing research data with colleagues or publishing findings difficult. To overcome these constraints, researchers typically convert .ACQ files to CSV or TXT for universal compatibility with spreadsheet software, MAT for advanced numerical analysis, or PDF and JPG for visualizing waveform graphs in reports. Users may also encounter .ACQ files generated by Siemens LMS Test.Lab or other legacy acquisition systems, all of which benefit from conversion to open standards.

Convert.Guru analyzes your ACQ file, detects the exact format, and lets you read the text inside.

The ACQ Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ACQ converter.
