Audio input and on/off
adc~ is the audio-to-digital converter for a signal-processing patch which can be used to route signal inputs from external devices or inputs into your patch. It can also be used to turn MSP's signal-processing on or off entirely.
|| You can create a adc~ object that uses one or more audio input channel numbers between 1 and 512. These numbers refer to logical channels and can be dynamically reassigned to physical device channels of a particular driver using either the DSP Status window, its I/O Mappings subwindow, or an adstatus object with an input keyword argument. If the computer's built-in audio hardware is being used, there will be two input channels available. Other audio drivers and/or devices may have more than two channels. If no argument is typed in, adc~ will have two outlets, initially set to logical input channels 1 and 2.
||on/off-flag (0 or non-zero) [int]
|| A non-zero number turns on audio processing in all loaded patches. 0 turns off audio processing in all loaded patches.
|| A list comprised of integers, sets the logical input channels for each signal outlet in order from left to right.
|| Double-clicking on adc~ opens the DSP Status window.
|| Opens the DSP Status window.
| 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 512). If the second number is 0, the outlet sends out the zero signal.
|| Turns on audio processing in all loaded patches.
|| 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.
|| Turns off audio processing in all loaded patches.
|| Closes the DSP Status window if it is open
The signal arriving at the computer's input is sent out, one channel per outlet. If there are no typed-in arguments, the channels are 1 and 2, numbered left-to-right; otherwise the channels are in the order specified by the arguments.
