In the Praat object window are listed all the audio clips and associated data derived from them. The verb buttons on the right hand side will change depending upon the type of object selected

Using the menu commands Read : Read from file... a WAV or MP3 file may be read in and added to the objects. Select an audio clip and click the Edit button. An edit window will open.

By default, this will show the audio waveform on the top half and the pitch contour on the bottom half. Clicking on the graph will select a single point of the audio clip. Clicking and dragging will select a portion of the audio clip. Readout of either instantaneous or average values will be indicated on the axises.
