Simple Synthesis |
|
From the Insert menu, choose Synthesis, and then choose Simple from the submenu to generate a simple waveform of a given shape, pitch, and length.
-
From the Insert menu, choose Synthesis, and then choose Simple from the submenu.
-
Choose a shape from the Waveform shape drop-down list to specify the shape of a single period of the waveform.
-
In the Length box, specify the length (in seconds) of the generated waveform.
-
In the Start Frequency box, specify the frequency of the waveform you want to generate or the starting frequency of the range you want to sweep.
Notes:
-
Aliasing can occur with many of these waveforms when using high frequencies because they are not band-limited.
-
When you choose Filtered noise from the Waveform shape drop-down list, Start Frequency determines the low-pass cut-off frequency.
-
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.
The available frequency range is limited by your current sampling rate. The highest frequency available will be the Nyquist frequency.
-
Drag the Amplitude fader to set the peak level of the waveform.
When Filtered Noise is selected in the Waveform shape drop-down list, the amplitude is affected by the frequency.
-
Choose a position from the Insert new waveform at drop-down list to determine where the generated waveform will be placed within the current data window.
