rand~

Band-limited random signal

Description

Use the rand~ object to generate a signal consisting of random values between -1 and 1 generated at a frequency specified by its input. It interpolates linearly between these values.

Examples

Use rand~ to create roughly band-limited noise, or as a control signal to create random variation

Arguments

initial-frequency [number]

Optional
Unitshz

Sets the initial frequency. The default value is 0. If a signal is connected to the inlet, the argument is ignored.

Attributes

Common Box Attributes

annotation [symbol]

Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.

background [int] (default: 0)

Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.

color [4 floats]

Sets the color for the object box outline.

fontface [int]

Sets the type style used by the object. The options are:

plain
bold
italic
bold italic

Possible values:

0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'

fontname [symbol]

Sets the object's font.

fontsize [float]

Sets the object's font size (in points).

Possible values:

'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'

hidden [int] (default: 0)

Toggles whether an object is hidden when the patcher is locked.

hint [symbol]

Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.

ignoreclick [int] (default: 0)

Toggles whether an object ignores mouse clicks in a locked patcher.

patching_rect [4 floats] (default: 0. 0. 100. 0.)

Sets the position and size of the object in the patcher window.

position [2 floats]

g/s(set)

Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.

presentation [int] (default: 0)

Sets whether an object belongs to the patcher's presentation.

presentation_rect [4 floats] (default: 0. 0. 0. 0.)

Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.

rect [4 floats]

g/s(set)

Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).

size [2 floats]

g/s(set)

Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.

textcolor [float]

Sets the color for the object's text in RGBA format.

textjustification [int]

Text Justification

Possible values:

0 = 'left'
1 = 'center'
2 = 'right'

varname [symbol]

Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.

Messages

int

Arguments

input [int]
The frequency at which a new random number between -1 and 1 is generated. rand~ interpolates linearly between random values chosen at the specified rate. If there is a signal connected to the inlet, the int is ignored.

float

Arguments

input [float]
The frequency at which a new random number between -1 and 1 is generated. rand~ interpolates linearly between random values chosen at the specified rate. If there is a signal connected to the inlet, the float is ignored.

signal

The frequency at which a new random number between -1 and 1 is generated. rand~ interpolates linearly between random values chosen at the specified rate.

Output

signal

A signal consisting of line segments between random values in the range -1 to 1. The random values occur at the frequency specified by the input.
