Waveforms

If you've ever worked with digital audio on a computer, you're probably familiar with waveforms (Figure 2.1). A waveform is a visual representation of an audio signal, showing changes in amplitude (verticaly-axis) over time (horizontal x-axis). The peaks and valleys in a waveform represent positive and negative pressure. If you zoom in while looking at a waveform in Audition, you'll find that you can see (and edit and tweak) the individual peaks and valleys quite readily (Figure 2.2). (I'll get into the editing and tweaking in Chapter 5.)
