saw~

Antialiased sawtooth oscillator

Description

Use the saw~ object to generate an anti-aliased sawtooth wave.

Examples

Spectral comparison of saw~ and phasor~

Arguments

initial-frequency [number]

Optional
Unitshz

Sets the initial frequency of the oscillator. The default is 0.

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

frequency [int]
In left inlet: Sets the frequency of the oscillator.

float

Arguments

frequency [float]
In left inlet: Sets the frequency of the oscillator.

signal

In left inlet: Sets the frequency of the oscillator.

In right inlet: (optional) A sync signal. When the control signal crosses from below 0.5 to above 0.5, the oscillator resets itself. A phasor~ object works well for this purpose. The classic use is to set this control signal to your fundamental frequency and "sweep" the left frequency input in a range somewhere several octaves higher than the fundamental.

synctrig

Arguments

trigger-value [float]
Sets the value which an input signal crosses at which the oscillator will reset itself.

Output

signal

An antialiased sawtooth waveform. An ideal, straight-line sawtooth wave generated in a computer contains aliased frequencies that can sound irritating. saw~ produces a nice, analog-esque output waveform.
