Description

Smooths an incoming signal across n samples. Each time an incoming value changes, it begins a linear ramp to reach this value.

Examples

rampsmooth~ performs linear smoothing on an input signal

Arguments

ramp-up-samples [int]

Optional

Number of samples for ramp-up

ramp-down-samples [int]

Optional

Number of samples for ramp-down

'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

signal

Each time an incoming value changes, the object begins a linear ramp over a specified number of samples to reach the new value.

ramp

Arguments

sample-count [int]
Specifies the number of samples over which a signal will be smoothed. Each time an incoming value changes, the rampsmooth~ object begins a linear ramp of the specified number of samples to reach the new value. The default value is 0.

rampdown

Arguments

ramp-down samples [int]
Specifies the number of samples over which a signal will be smoothed when an incoming value less than the current value arrives.

rampup

Arguments

ramp-up samples [int]
Specifies the number of samples over which a signal will be smoothed when an incoming value greater than the current value arrives.

Output

signal

The smoothed signal is sent out the outlet.
