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. Cycling '74 MSP MSP I/O start, stop Turn Audio On and Off TEXT_HERE start, stop Turn Audio On and Off TEXT_HERE (signal) Audio In Ch 1 TEXT_HERE (signal) Audio In Ch 2 TEXT_HERE Number of inputs 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 Audio 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. Enable/disable audio processing A non-zero number turns on audio processing in all loaded patches. 0 turns off audio processing in all loaded patches. Set the logical input channels for each signal inlet list comprised of integers sets the logical input channels for each signal inlet. Open the Audio Status window Double-clicking on adc~ opens the Audio Status window. Open the Audio Status window Opens the Audio Status window. Set the logical input channel for a signal outlet 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. Turn on audio processing in all loaded patches Turns on audio processing in all loaded patches. Turn on audio processing only in the patch in which this adc~ is located, and in subpatches of that patch 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. Turn off audio processing in all loaded patches Turns off audio processing in all loaded patches. Close the Audio Status window Closes the Audio 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.
