Making a Frequency Slice

This procedure shows how to make a Frequency Slice which displays the evolution of the level over time, at the frequency indicated by a cursor.

To Make a Frequency Slice:

  1. Open or calculate a time frequency representation.
  2. Click Reposition frequency slice to display the horizontal frequency cursor and the frequency slice in the time frequency representation.
    Figure 1. On the left is a time-frequency representation before making a frequency slice. On the right, the spectrum resulting from the frequency slice is displayed below the time-frequency representation.
  3. Click and drag the horizontal frequency cursor to position the cursor on the time frequency representation.
    Tip: You can position the horizontal cursor: click Reposition frequency slice , then click the required position in the time frequency representation.
  4. Click Reposition frequency slice to undo the time slice.

The frequency slice is done.
