Traditionally, DAWs use the acronym ADC
(for Analog to Digital Converter
)
to refer to the audio signal from your system's audio input device.
Far be it from us to stir those waters.
You can have multiple Hz.ADC
instances (typically 0, 1 or 2) in your scene
to capture signals from your system audio input devices.
// This JavaScript snippet creates a mono audio signal src from
// channel 1 (the Right channel) of the selected, presumably
// 2-or-more-channel, Audio Input.
let adc = ascene.NewAnode("Hz.ADC",
{cfg:"mono", preset:{numchan:1, chanoffset:1}});
// now wire adc into your scene.
