cross~

Third-order crossover filter

Description

Use the cross~ object as a pair of symmetrical low+high pass 3rd order filters with lowpass and highpass outlets you can use separately or in combination to form a crossover filter.

Examples

Split a signal into high and low frequency components

Arguments

cutoff-frequency [float]

Unitshz

Obligatory. The argument sets the initial cutoff frequency for the lowpass and the highpass parts of the output signal.

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

cutoff-frequency [int]
In right inlet: Converted to float. Sets the filter cutoff frequency for both the lowpass and the highpass parts of the output signal.

float

Arguments

cutoff-frequency [float]
In right inlet: Sets the filter cutoff frequency for both the lowpass and the highpass parts of the output signal.

clear

Sets the filters' output memories to 0(this is helpful in case you blow it up).

signal

In left inlet: Any signal to be filtered.

In right inlet: Sets the filter cutoff frequency for both the lowpass and the highpass parts of the output signal.

Output

signal

Out left inlet: The lowpass-filtered input signal.

In right inlet: The highpass-filtered input signal.

Together the lowpass and highpass filtered signals coombine to produce a flat frequency response equivalent to the input signal. The phase response for the filtered output is, however, slightly altered.
