Scale Amplitude The Scale Amplitude command increases or decreases the amplitude of the selected audio data, but maintains the shape of the waveform. To scale amplitude: In the Graphic Editor window, select the audio data you want to scale. From the Edit menu, choose Audio > Scale Amplitude. The Scale Amplitude dialog box appears. In the Change audio to 'N' % of current field, enter a value between 1 and 500. A setting of 100% is neutral which does not change volume level. Settings below 100% decrease amplitude and setting above 100% increase amplitude. Click OK. The amplitude changes, but the shape of the waveform does not change.
