#X text 8 46 Adc~ and dac~ provide real-time audio input and output
for Pd \, respectively \, whether analog or digital. By default they
are stereo but you can specify channel numbers as in:;

#X msg 37 273 set 5;
#X text 98 266 The "set" message to either dac~ or adc~ resets the
channel or channels. This requires Pd to restart DSP and so should
only be done at setup time \, not while audio is being computed.,

#X text 288 418 updated for Pd version 0.47;
#X text 35 348 If more than one dac~ outputs to the same channel \,
the signals are added. More than one adc~ may read the same input channel.
;
#X text 15 173 The actual number of channels Pd inputs and outputs
is set on Pd's command line or in the "audio settings" dialog. You
can open patches that want to use more channels \, and channel numbers
out of range will be dropped (dac~) or appear as zero (adc~).;
