chucker~ Reference

Segment audio and reorder it on looped playback

chucker~

Description

chucker~ takes a specified amount of audio data, stores the data in an internal buffer, divides the buffered data into equal sections, and allows the sections to be reordered on playback.

Arguments

buffer-size-in-ms [int]

An optional integer argument can be used to set the number of milliseconds to allocate for the recorded sound. (e.g. an argument of 8000 will allocate enough memory for a stereo output of 8 seconds)
Note: The actual allocation will be larger than what is specified by the argument, since the chucker~ object supports two buffers and provides for double-buffering.

Attributes

Common Box Attributes

annotation [symbol]

background [int] (default: 0)

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'

'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.

jspainterfile [symbol]

JS Painter File

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 [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

directions

Arguments

direction-specifier [list]
The word directions, followed by a 1 or 2 to indicate left or right channel and a list of integer values whose length is equal to the number of steps, sets the direction of playback for the sections. Playback direction is specified as follows:

1: forward (the default)
0: mute
-1: reverse

fademode

Arguments

mode [int]
Sets the fade method for segment smoothing. Modes include:
0: Classic (same as Max 5)
1: Pre-fade (fades use buffered audio, fade executes prior to segment transition)
2: Post-fade (fades use buffered audio, fade executes after segment transition)

freeze

Arguments

buffer-segment [int]
The message freeze 1 causes the current buffer segment to loop on playback. Sending the message freeze 0 resumes normal playback.

nstep

Arguments

number-of-steps [int]
The word nsteps, followed by an integer in the range 1 - 64, sets the number of equal portions into which the chucker~ object's internal buffer is segmented for playback.

signal

In left inlet: Left channel audio input.
In middle inlet: Right channel audio input.
In right inlet: An audio signal in the range 0. - 1.0 provides the audio sync input. This task is typically done using a phasor~ object's output as input.

smooth

Arguments

smooth-amount [float]
The word smooth, followed by a floating point number in the range 0. - 1.0, sets an amount of smoothing (crossfading) between the individual segments being reordered for playback.

steps

Arguments

channel and range [list]
The word steps, followed by a 1 or 2 to indicate left or right channel and a list of integer values whose range is between 1 and the number of steps and whose length is equal to the number of steps, sets the order of playback for the sections.
e.g. the message steps 1 4 3 2 1, steps 2 1 2 3 4, when sent to a chucker~ object whose number of steps is set to 4, will play the four left channel segments in reverse order, and the right channel in regular order. order
