normalize~
Scale on the basis of maximum amplitude
Description
normalize~ performs real-time normalization of its input by multiplying each input sample value by a scaling factor - computed as the maximum output value (sent either as a signal or a float in the right inlet) over the maximum signal input value received thus far.
Discussion
You can change the maximum input value with the reset message or with a float in the left input. If no argument follows "reset" the new maximum input value (and the initial maximum input value) is 0.000001.
Arguments
initial-maximum-output-amplitude[float]
optional
The initial maximum output amplitude. The default is 1.
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]: 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'
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]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
JS Painter File
patching_rect[4 floats]: 0. 0. 100. 0.
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
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]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 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]
write-only
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]
write-only
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[4 floats]
Sets the color for the object's text in RGBA format.
textjustification[int]
Sets the justification for the object's text.
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
Converted to float .
- maximum-output-amplitude
[int]
float
In right inlet: The maximum output amplitude may be sent as a float instead of a signal . If a signal is connected to the right inlet, a float received in the right inlet is ignored.
- maximum-output-amplitude
[float]
reset
In left inlet: The word reset , followed by a number, resets the maximum input amplitude to the number. If no number follows reset , or if the number is 0, the maximum input amplitude is set to 0.000001.
- maximum-input-amplitude
[float]
signal
In left inlet: The input signal is normalized -- scaled so that its peak amplitude is equal to a specified maximum.
In right inlet: The maximum output amplitude; an over-all scaling of the output.
Output
signal
The input signal is scaled by the maximum output amplitude divided by the maximum input amplitude.
