|Nebula||Surround scope setup options|
Selects between various commonly employed surround speaker arrangements.
Toggles phase-correlation display on and off.
This parameter controls whether the intensity of the particles are modulated by the overall audio level variations. In essence, when enabled, the color nuances will vary according to the relative amplitude of a frequency, allowing to monitor the relative amplitude spectrum variations. When disabled, the color will reflect the absolute audio level. You can also think of this as a kind of auto-gain setting.
This controls whether color variations should be smoothed in time or not. When engaged, color variations is slowed down a bit, which makes overall level transitions more obvious.
You should to enable this setting when you want to visualize quick level variations such as those that frequently occur in movie soundtracks.
Adds a constant blend amount to the particle. This ensures some of the particle is always blended into the image even if its original magnitude is low.
A low value for this setting has the effect of stabilizing the appearance of particles. With large values more of the spectrum dynamics are taken into account, and only peaks mostly come through.
Toggles between linear and logarithmic blending of the current particle with old particles.
The default is off, ie. linear blending, which tends to favor the display of peaks.
Logarithmic blending on the other hand preserves more of the full dynamic range of the data, and gives some visibility to lower levels also.
Controls</link> display persistence, i.e. the “fade to black” amount for a frame. Lowering this value retains past particles longer, whereas increasing this make them disappear faster.
Controls</link> the size of individual particles with respect to screen size.
Controls</link> the radius of the blur effect applied to past particles. Particles are “smeared” more and more as they become older, depending on this setting. Naturally, a bigger value increases the smearing, at the expense of processing power.
Choosing the value for this setting is really matter of taste, although please keep in mind values that above 5 will require a sufficiently powerful graphics card in order to maintain a responsive display.
Determines the amount of particles to display, relative to the default number used for the current screen size.
Toggles automatic adjustment of particle size with screen size. When enabled, the overall aspect of the display will remain similar even if the view size changes.
This defines how the particle color is determined:
Determines the start and end colors used with “Power grading” color mode selected.
