The lower left corner of the Audio Tool window is the status message display area. If any status information or error messages occur while using Audio Tool, the information is displayed here. For example, the current audio format is displayed there.
The lower right corner of the Audio Tool window displays the length of a recorded file (e.g., Length: 0:08.5). Whenever a sound segment is selected in the display canvas, brackets appear indicating the length of the selection (e.g., Length: 0:08.5 [0:00.9]). These brackets also appear when recording is initiated, and display the length of the newly recorded data (which is updated periodically).
