required: no
minimum: -100
maximum: 0
default: -30
unit: dB

osc

title: Oscillation
description: Oscillation can be useful to make the image move back and forth during long periods of sound. A value of 0 specifies no oscillation.

initial_zoom

title: Initial Zoom
description:

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.
  100% = no zoom
< 100% = zoom out (make the image smaller)
> 100% = zoom in (make the image larger)

type: float
readonly: no
required: no
minimum: 0
maximum: 5000
default: 100
unit: ‘%’

zoom

title: Zoom
description:

The amount that the audio affects the zoom of the image.
< 0% = Image will zoom out (get smaller) with more sound
  0% = no zoom
> 0% = Image will zoom in (get larger) with more sound

type: float
readonly: no
required: no
minimum: -100
maximum: 100
default: 0
unit: ‘%’

left

title: Left
description:

The amount that the audio affects the left offset of the image.
  0% = no left offset
> 0% = Image will move left with more sound

type: float
readonly: no
required: no
minimum: 0
maximum: 100
default: 0
unit: ‘%’

title: Right
description:

The amount that the audio affects the right offset of the image.
  0% = no right offset
> 0% = Image will move right with more sound

type: float
readonly: no
required: no
minimum: 0
maximum: 100
default: 0
unit: ‘%’

up

title: Up
description:

The amount that the audio affects the upward offset of the image.
  0% = no upward offset
> 0% = Image will move up with more sound

type: float
readonly: no
required: no
minimum: 0
maximum: 100
default: 0
unit: ‘%’

down

title: Down
description:

The amount that the audio affects the downward offset of the image.
  0% = no downward offset
> 0% = Image will move down with more sound

type: float
readonly: no
required: no
minimum: 0
maximum: 100
default: 0
unit: ‘%’

clockwise

title: Clockwise
description:

The amount that the audio affects the clockwise rotation of the image.
  0% = no clockwise rotation
> 0% = Image will rotate clockwise with more sound

type: float
readonly: no
required: no
minimum: 0
maximum: 360
default: 0
unit: degrees

counterclockwise

title: Counterclockwise
description:

The amount that the audio affects the counterclockwise rotation of the image.
  0% = no counterclockwise rotation
> 0% = Image will rotate counterclockwise with more sound

type: float
readonly: no
required: no
minimum: 0
maximum: 360
default: 0
unit: degrees

window_size

title: Window Size
description: The number of samples that the FFT 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.
