Playing the audio file

Audio files display in the Labelbox editor with a waveform for visualization and basic player controls. Use the play/pause button to begin audio playback, and press the back/forward 10-second buttons to quickly replay or advance playback. You can also click anywhere on the waveform to instantly move the playhead to your desired location.

Classifying the audio file

The classification questions added to the labeling project during project setup will appear in the left-hand panel. Labelers may use their mouse or the specified keyboard shortcuts to activate various questions and apply the relevant values.

Submitting the audio label

Once the labeling task is completed, the labeler may click Submit (or press E) to submit the completed label and advance to the next asset.
