Global classifications only
Classifications can be applied at the file-level only. The editor does not currently support classifications at the timestamp level, for example, Agent speaking from 1:05 to 1:38.

Navigate audio files

Audio files display in the 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 to your desired location.
