TotalRecall is designed for precise scoring and timing of participant responses during verbal tasks, especially Free Recall. However, it can be used for many kinds of audio annotation. TotalRecall displays an audio recording as a self-scrolling waveform that automatically keeps up with audio playback.

Please visit our tutorial page for screencasts and tips for using TotalRecall.

System Requirements

TotalRecall currently runs on Mac OSX and Windows. A Linux version will be released shortly. We plan to support these these configurations.

!Total Recall requires a Java Runtime Environment, version 5 or higher. Most computers come with Java pre-installed, so you can probably download and run the program without worrying about system requirements. If it turns out you don't have Java, you can download it free here.

Bugs and Feature Requests

Please report all feedback and bug reports to:

You can also email that address to request new features for the next release of the program.



TotalRecall is free and open-source software, released under the GNU General Public License, version 3. We encourage other groups to modify and improve the program. Please drop us a line if you're interested in developing TotalRecall or borrowing its code.


TotalRecall uses the OpenMary TTS signal processing library (`signalproc.jar`) for bandpass filtering (BSD). The default audio playback implementation is derived from's BasicPlayer (GPL). Drag and drop support in Linux thanks to FileDrop (Public Domain).
