Build multimedia experiments and millisecond-accurate reaction-time studies — no code required. Trusted by research labs since 1997, and completely rebuilt for 2027.
Design a study in an intuitive interface or your favorite spreadsheet. Most researchers can build a working experiment in 15–20 minutes.
DirectRT is fully DirectX, with responses timed against the actual screen refresh — eliminating the 10–17 ms of error that plagues ordinary software.
Both programs write friendly, single-file output with variable definitions built in — plus utilities to merge data collected across many computers.
For three decades, psychologists, neuroscientists, cognitive scientists, and marketing researchers have run studies, dissertations, and published findings on Empirisoft software — across generations of Windows and generations of students. Software appears and disappears; this has quietly kept working.
MediaLab designs studies and manages participants. DirectRT delivers millisecond-accurate experimental control. Use either program on its own — or combine them into one seamless workflow.
The most versatile presentation and questionnaire tool for Windows. Build multimedia experiments and surveys with dozens of question types.
Present text, images, audio, video, PowerPoint, and web content — then export clean data straight to Excel or SPSS.
Purpose-built for cognitive and perception tasks that demand millisecond precision. Construct reaction-time experiments in a familiar spreadsheet.
Collect response data with precision ordinary software simply cannot match.
For the first time since the 1990s, MediaLab and DirectRT have been rewritten from scratch on the most modern Windows platforms and APIs. The same trusted workflow and full backward compatibility with your existing studies — now faster, sharper, and built for years of new capabilities to come.
Re-engineered on today’s development platform and APIs — the aging engine that capped what was possible is gone for good.
Your existing experiments, scripts, and data files carry straight across and simply keep working.
Every modern media format, full Unicode including right-to-left languages, and modernized TTL signaling for EEG, eye-tracking, and other lab equipment.
This release is a foundation, not a finish line — a steady stream of new features is already on the way.
“Powerful enough for the most demanding experiment, simple enough to master in an afternoon. That balance has guided every version since 1997.”
