Abstract
A method for displaying reference waveforms to facilitate visual identification of different points such as maximum points and minimum points of an audio clip is provided. The reference waveform includes points that correspond to points on the original audio waveform, except that some or all points on the reference waveform are accentuated to easily identify the positions of the corresponding points on the audio waveform. The reference waveforms are especially useful when an audio waveform (or at least a portion of the clip) has low volume which makes the visual identification of the maximums and minimums of the waveform difficult. Displaying the reference waveform which accentuates the peaks and valleys of the original waveform facilitates the identification of these maximums and minimums.
