  • Anatomy of the Viewer's Audio Tab

    The Audio tab in the Viewer window is where you review, mark, and edit single audio clips opened from the Browser or the Timeline. You can see the audio waveforms of audio clips, and in addition to the editing functions, you can use onscreen controls to adjust the level and stereo pan settings (Figure 12.6 ).

    Onscreen controls and displays

    Editing digital audio requires different interface tools than editing digital video. When you open an audio clip in the Viewer, a graph of the audio waveform appears on the Audio tab, and the playhead travels across a stationary waveform image.

    The Audio tab retains the transport controls from the Video tab interface in the lower part of the tab, but it has its own set of onscreen controls in the upper part.

    Here's a brief rundown of the onscreen controls unique to the Audio tab (Figures 12.7 and

    12.8 ):

    Level slider: Use to adjust the amplitude or volume of the audio clip.

    Figure 12.7. Controls displayed in the upper half of the Audio tab.

    Pan slider: Use to adjust stereo panning or swapping of the left and right channels. Single channel (mono) clips use the Pan slider for left/right positioning of mono audio.

    Reset (X) button: Use to delete all marked points in the audio timeline and reset the level and pan values to their original settings.

    Drag hand: This is your handle for drag-and-drop editing. Drag to move the audio clip with edits to another window, such as the Browser or the Timeline.

    Audio tab ruler: This shows the timecode for the audio displayed. Edit point overlays appear along the ruler. You can adjust the time scale with any Zoom tool, selector, or slider.

    In and Out points: These appear in both the Scrubber bar and the ruler.

    Level line graph: Both a tool and an indicator, it graphs level changes by indicating the amplitude of the audio. You can also drag the Level line graph to adjust the overall level of your audio clip, or you can drag keyframes to create dynamic volume effects.
