dspstate~ Reference

Report current DSP settings

dspstate~

Description

dspstate~ can be used for calculations that require the sampling rate of current DSP processing block size. You can also use the leftmost outlet to trigger some event when the audio is turned on or off.

Examples

Trigger an action when audio is turned on or off use sample rate to calculate timings

Discussion

dspstate~ outputs state information automatically whenever the audio is turned on or off. You can also get the information by sending a bang. Connecting a signal to the dspstate~ object's inlet reports information about that signal, although currently, all signals have the same sampling rate and vector size. Note that dspstate~ will not output anything if the audio is not turned on in its window.

Arguments

None.

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.

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

bang

Triggers a report out the dspstate~ object's outlets, telling whether the audio is on or off, the current sampling rate, and the signal vector size.

signal

If a signal is connected to the dspstate~ object's inlet, dspstate~ reports that signal's sampling rate and vector size, rather than the global sampling rate and signal vector size.

Output

float

Out second outlet: Sampling rate of the connected signal or the global sampling rate.

int

Out left outlet: If the audio is on or being turned on, 1 is sent out. If the audio is off or being turned off, 0 is sent out.

int

Out third outlet: Current DSP signal vector size.

int

Out fourth outlet: Current I/O signal vector size.
