pitchshift~

Ztx-based real-time pitchshifting

Description

Use the pitchshift~ object to load a perform pitch-shifting on an input signal.

Arguments

channels [int]

Optional

An optional argument can be used to specify the number of channels of the signal to be processed (default = 1).

Attributes

enabled [int]

Enable or disable pitchshifting.

pitchshift [float] (default: 1.)

Set the pitchshifting as a factor of the original pitch (i.e. 2.0 = doubling of pitch, .5 = halving of the original pitch, etc.).

pitchshiftcent [int] (default: 0)

Set the amount of pitchshift as positive or negative cent values (i.e. 100 = semitone up, -1200 = octave down). Cents may be specified as ints or floats.

quality [int]

Pitch shifting output quality.


Possible values:

'basic' ( Basic quality (the default) )
'good' ( Good quality )
'better' ( Better quality )
'best' ( Highest quality )

reportlatency [int]

Enable/disable reporting latency, in samples, introduced by the pitchshift~ object's calculations. Latency is output from the object's right-hand outlet in the form of a message in the form latency [number-of-samples].

usecents [int]

Enable/disable the use of cent values in the second inlet of the pitchshift~ object to specify pitch change.

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]

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

getlatency

The word getlatency, followed by a zero or one, toggles reporting the latency, in samples, introduced by the pitchshift~ object's calculations. Latency is output from the object's right-hand outlet in the form of a message in the form latency [number-of-samples].

signal

The pitch of signal(s) in the left input(s) will be shifted. A signal in the rightmost inlet defines the shifting as a factor of the original pitch or in cents (when usecents is enabled).
