Array Expand Compress

Resizes an array by expanding or compressing it using interpolation. The output size equals factor x input size.

For example, a 512-element input with factor = 0.5 produces a 256-element output, and factor = 2 produces a 1024-element output.

Useful for stretching or shrinking spectra, lookup tables, or any array data.

input array

expand with factor=2

expand with factor=0.5

Settings

bypass

Bypasses the module processing when activated (ON).

  • OFF (0): Module processes normally
  • ON (1): Input passes directly to output without processing

array in

Array input flow(s).

array out

Array output flow(s).

factor

Compress expand factor:

  • if factor < 1, provides a compression.
  • if factor > 1, provides an expansion.
  • if factor = 1, no changes.

mode

Interpolation mode used to calculate the new array:

  • linear interpolation -- blends between neighboring values for smooth results. Best for audio and continuous data.
  • accumulation -- adds input values into the nearest output bin. Useful for histograms or spectral data. 
     newIndex = trunc(factor*oldIndex);
 output[newIndex] := output[newIndex]+input[oldIndex]
  • no interpolation -- nearest-neighbor mapping, no blending. Best for arrays of discrete values such as colors or indices. 
     inIndex = trunc(outIndex/factor);
 output[outIndex] := input[inIndex]
Common Settings

info

show manual

Button. Opens the manual page of the selected object (or of its parent module for a control) in the web browser. If no page exists for this object, an error is traced in the trace panel.

For more details about information/help creation, see create-help-file.

description

Free multi-line text attached to the module, saved with the patch. It is only meant as an internal note for the patch designer: it is not displayed in the interface.

ID's

visible only in god mode, see setup-panel-tab-expert.

unique ID

Read-only, not saved. Current private numeric ID of the object, used internally to identify it (for example as the target of a bind ID).

preset ID

Read-only, not saved. Private ID used to store and recall the values of this control in presets.

recreate ID

Button. Generates a new unique ID, original ID and preset ID for the object. Use it if you experience difficulties in Polyphonic mode or if two objects share the same ID. Preset values and binds referring to the old IDs are lost.

Object Remote Address

absolute

Read-only, not saved. Absolute address of the object in the Usine objects tree, built from the workspace root. This is the address to use to reach the object from scripts, the objects panel or remote messages. Only shown for objects that are registered in the objects list. See objects-address.

local

Read-only, not saved. Address of the object relative to the current patch, valid inside that patch only. See objects-address.

user addr

Free user-defined address for the object (empty by default). When set, the object is also registered in the objects tree under this name, so it can be reached independently of its position in the workspace (the value is also reported in the mouse-over and mouse-down chunks). Changing it rebuilds the objects list. Only available on objects that support a user address. See objects-address.
