Signal Generator Dialog

To open the Signal Generator dialog, select File > Tools > Signal Generator.

Audio Properties: Opens the Audio Properties dialog in which you can select sample rate, bit depth, etc.
Global Gain: Adjusts the global level of all combined layers.
Number of Layers: Determines the number of layers, for example, the number of independent signals to be combined.
All Channels/Left Channel/Right Channel: Determines whether the settings on the tab are applied to the left or right channel of the selected layer, or to both channels. This option is only available for stereo files.
Copy: Copies all settings of the current layer.
Paste: Pastes the settings to the selected layer.

Note
Clicking Paste replaces the source, frequency, and level settings on all tabs, not just on the selected one.
Generate: Applies the settings.

Source Tab

Waveform: Allows you to select a waveform for the selected layer.
Width: If you select one of the pulse waveforms, you can set this parameter to the width of the pulse, specified as a percentage or a number of samples.
Angle (0-359°): Sets the phase of the signal for the selected layer.
Adjust Signal Length to End on a Cycle Boundary: If this option is activated, the generated waveform ends with a complete cycle, regardless of the phase setting.

Frequency Tab

Envelope Section

In this section, you can set up the frequency envelope of the selected layer. The envelope consists of four frequency values and three duration values in between the frequency values.

If you want to set a static frequency (no envelope curve), make sure that all time values are set to 0, and set the frequency with the Median Freq. 2 parameter.

Vibrato Section

In this section, you can add a vibrato to the frequency of the selected layer. You can select a waveform for the vibrato, set the frequency, and adjust the intensity.

Change Frequency at Cycle Boundaries

If this option is activated, the vibrato is not continuously applied from sample to sample, but recomputed after each cycle.

Linear Frequency Variations

If this option is activated, the frequency varies linearly.

Level Tab

Envelope: In this section, you can set up the amplitude envelope of the selected layer. The envelope consists of three level values and three duration values in between the level values. In addition, Silence Before and Silence After allow you to include a period of silence before or after the signal of the selected layer.

Note
Overall Gain determines the overall level of the layer.
Tremolo: In this section, you can add a tremolo (continuous level variation) to the selected layer. You can select a waveform for the tremolo, set the frequency, and adjust the intensity.
Change Level at Cycle Boundaries: If this option is activated, the tremolo is not continuously applied from sample to sample, but recomputed after each cycle.
DC Offset: Allows you to add a DC offset to the signal of the selected layer.
Overall Gain: Allows you to set an overall level for the selected layer.
