Annotation

Annotation Pro is a tool for annotation of audio and text files. You can create many time-aligned annotation layers. It is very easy to select fragments of recordings, dynamically zoom to selection or to a point with the mouse scroll, play, re-play and loop the sound.

Spectrogram with the possibility of switching on/off the segment boudaries supports precise visual inspection.

Workspace

Workspace functionality enables comfortable file management, grouping files, opening previously stored file collections. You will not need to dig through folders and files in search for your recordings and annotations. Workspace automatically opens collections of pairs audio + annotation. Additionally, this option offers basic statistics for file collections, e.g. number of actions related to opening the file, modifications, re-plays or working status of file (accepted or not).

Graphical Representation of the Feature Space

Graphical representation of the feature space is an innovative solution applied to a general purpose annotation software tool. The graphical representation enables using non-categorial features for the annotated recordings or texts. Thanks to this solution it is possible to easily apply continuous (or any desired) rating scales to annotation of your data (e.g. annotation of emotion).

Perception Tests

Annotation Pro supports the design and conducting of Perception Tests. You can decide which operations will be available for the participants of your test: anonymity of the test, hiding file names, the number of signal repetitions, availability of editing options, which annotation layers are accessible during the test, etc.
