SoundIn is a convenience UGen to read audio from the input of your computer or soundcard. It is a wrapper link::Classes/UGen:: based on link::Classes/In::, which offsets the index such that 0 will always correspond to the first input regardless of the number of inputs present.

On Intel based Macs, reading the built-in microphone or input may require creating an aggregate device in AudioMIDI Setup.
