Generating simple waveforms
The Simple Synthesis tool is used to generate simple waveforms of a given shape, pitch, and length.
1.
From the Tools menu, choose Synthesis, and choose Simple from the submenu. The Simple Synthesis
dialog appears.
2.
From the Waveform shape drop-down list, choose a shape to specify the shape of a single period of the
current operator's waveform.
3.
In the Length box, specify the length (in seconds) of the generated waveform.
4.
In the Start Frequency box, specify the frequency of the waveform.
5.
If you want to sweep a range of frequencies, select the End Frequency check box and specify an ending
frequency in the box.
Select the
Log Sweep check box if you want to sweep the range logarithmically; when the check box is
cleared, the sweep is linear.
6.
Use the Amplitude fader to set the peak level of the waveform.
Note:
When you choose Noise in the Waveform shape drop-
down list, the amplitude is affected by the specified cutoff
frequency.
7.
From the Insert new waveform at drop-down list, choose a position to determine where the waveform is
placed in the data window.
8.
Click OK.
