adstatus

Report and control audio driver settings

Description

Use the adstatus object to control Max audio settings.

Examples

adstatus lets you monitor and change audio parameters from within your patch

Arguments

Controllable-settings: [symbol]

The first argument is a symbol that specifies the setting to be controlled by the adstatus object. Some settings require an additional integer argument. The possible settings are:

cpu: Reports current CPU utilization.
cpulimit: Reports and sets the CPU utilization limit as a percentage from 0-100.
driver: Lists the available audio drivers and allows the current one to be changed.
info: Reports the number of function calls and signals used in the top level
input (Requires an additional argument specifying a logical channel number (used by the adc~ object) between 1 and 512): Lists the available audio driver input channels and allows the current setting to be changed.
iovs: Reports the available I/O vector sizes of the current audio driver and
latency: If supported by the audio driver, reports the input and output latencies of the driver in samples.
numinputs: Reports the number of input channels of the current audio driver.
numoutputs: Reports the number of output channels of the current audio driver.
option (Requires an additional argument specifying the option number (starting at 1): If the current audio driver uses the numbered option, reports the available choices for setting the value of the option.
optionname (Requires an additional argument specifying the option number (starting at 1): If the current audio driver uses the numbered option, the name of the option is reported.
output (Requires an additional argument specifying a logical channel number (used by the dac~ object) between 1 and 512): Lists the available audio driver output channels and allows the current setting to be changed.
overdrive: Controls the setting of overdrive mode (where the scheduler runs in a
sigvs: Reports the available signal vector sizes and allows the current signal vector size setting to be changed.
sr: Reports the available sampling rates and allows the current sampling rate setting to be changed.
switch: Turns the DSP on or off.
takeover: Controls the setting of scheduler in audio interrupt mode.
timecode: If supported by the audio driver, reports the current timecode value.

Messages

bang

In left inlet: Reports the current state of the setting. In many cases, messages are sent out the adstatus object's left outlet to set a pop-up menu object to display the current setting with a set message. In these cases, the numerical value of the setting is sent out the adstatus object's right outlet. The exact behaviors are listed in the Output section below.

int

Arguments

input [int]
In left inlet: Changes the setting. In most cases, the number will correspond to the index of the menu item whose value was set by the bang message to adstatus.

  (inlet1)

Arguments

input [int]
In right inlet: If the adstatus object is used with the input, iovs, output, sigvs, sr settings, an int in the right inlet sets the value numerically rather than by using a menu index (see the reset or loadbang messages). For all other settings, a number in the right inlet behaves identically to one in the left inlet.

float

Arguments

input [float]
In left inlet: Changes the setting. In most cases, the number will correspond to the index of the menu item whose value was set by the bang message to adstatus.

loadbang

In left inlet: Reports the state of the setting upon loading the patch. In many cases, messages are sent out the adstatus object's left outlet to set a pop-up menu object to display the current setting with a set message. In these cases, the numerical value of the setting is sent out the adstatus object's right outlet. The exact behaviors are listed in the Output section below.

override

Arguments

flag [int]
In left inlet: The word override, followed by a 1, turns on override mode for the setting associated with the object. When override mode is enabled, any change to the setting is not saved in the MSP Preferences file. The message override 0 turns override mode off. By default, override is off for all settings. However, some settings are specific to audio drivers and may not be saved by the driver.

set

Arguments

logical-channel-number [int]
In left inlet: The word set, followed by a number between 1 and 512, changes the logical channel associated with an adstatus input or adstatus output object. The current real audio driver input or output channel set for the new logical channel is sent out the object's outlets.

set

Out left outlet: When a bang message is received or when the value of the setting that has a menu-style output is changed, the word set, followed by a number with a menu item index (starting at 0) is sent out. Here are details of outputs from the left outlet for specific settings with menu-style outputs:

4. time code flags

5. time code frame rate

various

Out left outlet: For many settings, a series of messages intended to set up a pop-up menu object are sent out the left outlet when the reset or loadbang message is received by adstatus. See the reset message in the Input section for more details.

The following settings have a menu-style output: driver, input, iovs, output, sigvs, sr, switch, and takeover.
