Dance¶
Description
This effect/filter is an audio visualization effect that zooms, moves and rotates the image proportional to the magnitude of the audio spectrum.
Using the Zoom alone creates a cool pump effect in sync with the beats.
Parameters
Parameter |
Value |
Description |
|---|---|---|
Low Frequency |
Integer |
The low end of the frequency range to be used to influence the image motion (Hz) |
High Frequency |
Integer |
The high end of the frequency range to be used to influence the image motion (Hz) |
Level Threshold |
Integer |
The minimum amplitude of sound that must occur within the frequency range to cause the image to move (dB) |
Oscillation |
Integer |
Oscillation can be useful to make the image move back and forth during long periods of sound (Hz). A value of 0 specifies no oscillation. |
Initial Zoom |
Percent |
The amount to zoom the image before any motion occurs. This can be used to avoid black on the sides of the image when it moves. |
Zoom |
Percent |
The amount that the audio affects the zoom of the image. |
Left / Right |
Percent |
The amount that the audio affects the left / right offset of the image. |
Up / Down |
Percent |
The amount that the audio affects the up / down offset of the image. |
Clockwise / Counter Clockwise |
Degree |
The amount that the audio affects the rotation of the image. |
Window Size |
Integer |
The number of samples that the FFT[1] will be performed on. If Window Size is less than the number of samples in a frame, extra samples will be ignored. If Window Size is more than the number of samples in a frame, samples will be buffered from previous frames to fill the window. The buffering is performed as a sliding window so that the most recent samples are always transformed. |
Initial Zoom
100% |
no zoom |
< 100% |
zoom out (make the image smaller) |
> 100% |
zoom in (make the image larger) |
Zoom
< 0% |
Image will zoom out (get smaller) with more sound |
0% |
no zoom |
> 0% |
Image will zoom in (get larger) with more sound |
Left / Right
0% |
no offset |
> 0% |
Image will move left / right with more sound |
Up / Down
0% |
no offset |
> 0% |
Image will move up / down with more sound |
Clockwise / Counter Clockwise
0% |
no rotation |
> 0% |
Image will rotate with more sound |
