Once you’ve opened a waveform file you will notice a toolbar in the bottom left-hand corner.
The Playbar is for playback of the specific file. The time and level rulers located across and left of the sound file allow you gauge the location and amplitude of the sound file. There is also a zoom control which allows you to change the view both the horizontal and vertical axis of the sound file.
After you open a file, you can play it by clicking the Play All button on the Transport bar or by hitting the spacebar.
Click to position cursor in the data window. A flashing cursor (spanning the height of the display) will display itself. Click the Play button on the Transport bar or hit the spacebar. The file plays from the cursor position.
You can play audio in a continuous loop by selecting Loop Playback in the toolbar, options or by pressing Q on the keyboard.
You can play specific portions of audio data by creating selections in the waveform display. Drag the mouse within the data window. Notice that the waveform is selected as the mouse is dragged. Click the Play button or press the spacebar. Now only the selection plays.
