Signal Generator Dialog

This dialog allows you to generate complex synthesized sounds in mono or stereo.

  • 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.
