mc.dac~
Multichannel audio output and on/off
Description
The mc.dac~ ("digital-to-analog converter") object sends its signal inputs to audio hardware. Double-click on an mc.dac~ to open the Audio Status window to configure audio settings and hardware.
Arguments
outputs[symbol]
optional
When mc.dac~ has no arguments, it sends all channels of its connected multichannel input to audio output channels starting at logical channel 1.
When mc.dac~ has channel number arguments, it sends channels of its connected multichannel input to the specified audio output channel(s). If there are more channels in the multichannel input than channel arguments, the additional channels of the input are ignored.
If a symbol is provided as the first argument to a mc.dac~ object, its output will be sent to the Max mixer. If mc.dac~ instances in a patcher hierarchy share the same name they will use the same mixer output.

Sets the position and size of the object in the patcher window.
position[2 floats]
write-only

presentation[int]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 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]
write-only
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]
write-only
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.

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
A non-zero number turns on audio processing in all loaded patches. 0 turns off audio processing in all loaded patches.
- on/off-flag
[int]
list
A list of numbers sets the logical output channels for each channel in the multichannel input starting with the first input channel. For example, sending 3 4 5 to mc.dac~ will assign the first channel in an input multichannel signal to audio output channel 3, the second channel of the input to audio output channel 4, and the third channel of the input to audio output channel 5.
- output-channel-designations
[list]
(mouse)
Double-clicking on mc.dac~ opens the Audio Status window.
open
Opens the Audio Status window.
set
The word set , followed by a number, sets the logical output channels for the first channel in the input multichannel signal. For instance, set 3 assigns the first channel of the input to logical output channel 3. To assign multiple channels, use the list message.
- output-channel-designation
[int]
signal
The mc.dac~ object sends the audio in its multichannel input to audio output channels. The Arguments section describes how audio channels in the multichannel input are assigned to audio outputs. The signal must be between -1 and 1 to avoid clipping.
start
Turns on audio processing in all loaded patches.
startwindow
Turns on audio processing only in the patch in which this mc.dac~ 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
Audio
mc.dac~ produces no output internal to the application. Signals received in its inlets are sent to its assigned logical audio output channels. You can assign logical channels to device output channels in the I/O Mappings subwindow of the Audio Status window.
