An open-source, multi-platform graphical tool for marking word onsets




WavMark 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. WavMark displays an audio recording as a self-scrolling waveform on the screen which automatically keeps up with audio playback.


File Type
WavMark.mpkg Mac OSX installer
WavMark.msi Windows installer
WavMark.jar Multi-platform executable 0.1

Getting Started

Try opening the sample audio file in this zipped directory. If you don't change the directory structure, wordpool words to choose from should automatically appear in the wordpool display. Check the menu for actions and keybindings available to the user.

System Requirements

WavMark is written in pure Java, and should run on all platforms with a Java SE Runtime Environment, version 5 or higher (including Mac, Linux, Windows, Solaris, and others). Most computers come with Java pre-installed, so you can probably run the installers above without worrying about system requirements. If it turns out you don't have Java, you can download it free here.
