adc~ Reference

Audio input and on/off

adc~

Description

The adc~ ("analog-to-digital converter") object outputs one or more signals (one per outlet) with audio from hardware input devices.

Examples

Arguments

inputs [int]

Optional

If adc~ has one numeric argument, it determines the number of outlets that produce signals from audio input hardware starting with logical input channel 1. If adc~ has more than one argument, it is taken as a list of logical input channels assigned to its outlets. If no arguments are supplied, adc~ will have two outlets, initially set to logical input channels 1 and 2.

If a symbol is provided as the first argument to adc~, its output will come from a named inport port in the Max mixer. If adc~ instances in a patcher hierarchy share the same name they will use the same mixer input port.

int

Arguments

on/off-flag [int]
A non-zero number turns on audio processing in all loaded patches. 0 turns off audio processing in all loaded patches.

list

Arguments

input-channel-designations [list]
list comprised of integers sets the logical input channels for each signal inlet.

(mouse)

Double-clicking on adc~ opens the Audio Status window.

open

Opens the Audio Status window.

set

Arguments

logical-output-channel [int]
logical-input-channel [int]
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 1024). If the second number is 0, the outlet sends out the zero signal.

start

Turns on audio processing in all loaded patches.

startwindow

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.

stop

Turns off audio processing in all loaded patches.

wclose

Closes the Audio Status window if it is open

Output

signal

Audio from hardware input devices is output as a series of signals, one per outlet.
