Sound Generator Settings
The last tab of the Sound Generator, the one with the gear icon, holds the settings that apply to the Sound Generator as a whole rather than to one particular sound: the sampling rate it generates at, and the scale of the resonance curve. To open the Sound Generator, choose .
Changes on this tab take effect at once. These settings are not part of a Sound Generator profile: choosing a profile leaves them as they are, and saving one does not store them.
Sampling Rate
- Sampling Rate
-
The number of samples per second, in Hz, at which the Sound Generator computes its sound. The default is 44100 Hz. You can choose 11025, 22050, 44100 or 48000 Hz, and VoceVista Pro also offers 88200, 96000, 176400 and 192000 Hz.
The sampling rate sets the highest frequency the generated sound can contain: half the sampling rate, which is 22050 Hz at the default. Overtones above that frequency are left out (see Number on the Fundamental and Overtones tab). A lower rate therefore cuts the sound off at a lower frequency, while a higher rate lets it contain higher frequencies.
Generate adds the sound to the current recording. If that recording has a different sampling rate, the sound goes into a new recording at this rate instead. So when you want to add generated sounds to an existing recording, set the rate to the rate of that recording.
The sampling rate is shared with the rest of VoceVista:
-
It is the same setting as Sampling Rate in the Sound Generator category of the Advanced Settings. Changing it in one place changes it in the other.
-
It is also the rate at which note sliders and piano keys play.
-
When the Sound Generator is chosen as the Input Device in the Recording Settings, recordings from it use this sampling rate too.
Resonance Intensity Scale
|
Available in VoceVista Video and higher
These settings only have an effect in VoceVista Video and higher, the editions with resonances. |
The resonance curve shows how strongly the resonances of the Sound Generator amplify each frequency. It is drawn on the spectrum when Show resonance curve is checked on the Resonances tab. The curve has an intensity scale of its own, separate from that of the spectrum, so you can fit the curve to the view without changing how the spectrum itself is shown.
- Top
-
The level, in dB, at the loud end of the spectrum’s intensity axis. Raising it moves the curve toward the quiet end, and lowering it moves the curve toward the loud end. The default is -20 dB, and you can set values from -100 to 50 dB.
- Range
-
How many dB the scale spans, from Top down to the quiet end of the axis. A smaller range makes the peaks and valleys of the curve taller, while a larger range flattens them. The default is 150 dB, and you can set values from 10 to 250 dB.
Change these settings when the curve runs off the edge of the spectrum, or when it is too flat to read.
