Vector scope

Usage

The vector scope tool is displayed when a stereo input is detected, otherwise the display will switch to Surround scope 22.1 provided if your edition of FLUX:: Analyzer includes this option.

Vector scope display in surround (with selection menu).

Modes in Surround :

L-R

Use only Left and Right Channels.

Front

Use a stereo down mix with all front channels.

Rear

Use a stereo down mix with all Rear channels.

Stereo downmix

Use a stereo down mix with all channels.

Lt/Rt downmix

Use a Lt/Rt down mix with all channels.

LR-Lfe

Use a mono summation of Left and Right + the Lfe (sub) channel.

Center-Lfe

Use Center + Lfe (sub) channel.

Front-Lfe

Use a mono summation of the front channels + the Lfe (sub) channel.

Note

Vector scope setup options

Fs

Over-sampling factor in multiples of FS, that is the incoming audio is up-sampled as necessary to reach this multiple times 48kHz. Increasing this value increases the display precision and reactivity, at the expense of a little CPU overhead.

Blending

Controls the amount of particle blending with the current image, from 1 to 100%. A higher value gives more priority to the incoming audio over past frames.

Fading

Controls 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.

Size factor

Controls the size of individual particles with respect to screen size.

Blur kernel size

Controls 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.

Note

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.

Color mode

This defines how the particle color is determined: * Static color: use only particle start color (see below) * Power grading: color is modulated by overall signal RMS power * Dynamic grading: color is modulated by signal dynamics * Pw+Dyn grading: mix of the two previous modes
