adc~

Audio input and on/off

Description

The adc~ ("analog-to-digital converter") object outputs one or more signals (one per outlet) with audio from hardware input devices.

Examples

Arguments

inputs [int]

Optional

If adc~ has one numeric argument, it determines the number of outlets that produce signals from audio input hardware starting with logical input channel 1. If adc~ has more than one argument, it is taken as a list of logical input channels assigned to its outlets. If no arguments are supplied, adc~ will have two outlets, initially set to logical input channels 1 and 2.

If a symbol is provided as the first argument to adc~, its output will come from a named inport port in the Max mixer. If adc~ instances in a patcher hierarchy share the same name they will use the same mixer input port.

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]

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

Arguments

on/off-flag [int]
A non-zero number turns on audio processing in all loaded patches. 0 turns off audio processing in all loaded patches.

list

Arguments

input-channel-designations [list]
list comprised of integers sets the logical input channels for each signal inlet.

(mouse)

Double-clicking on adc~ opens the Audio Status window.

open

Opens the Audio Status window.

set

Arguments

logical-output-channel [int]
logical-input-channel [int]
The word set, followed by two numbers, sets the logical input channel for one of the object's signal outlets. The first number specifies the outlet number, where 1 is the leftmost outlet. The second number specifies the logical input channel (from 1 to 1024). If the second number is 0, the outlet sends out the zero signal.

start

Turns on audio processing in all loaded patches.

startwindow

Turns on audio processing only in the patch in which this adc~ is located, and in subpatches of that patch. Turns off audio processing in all other patches.

stop

Turns off audio processing in all loaded patches.

wclose

Closes the Audio Status window if it is open

Output

signal

Audio from hardware input devices is output as a series of signals, one per outlet.
