public class ChannelIn
extends SynthUnit

ChannelIn unit. Provides mono signal from audio line in or microphone. When you create this unit, you must specify which channel you want to use. To enable audio input, the flag Synth.FLAG_ENABLE_INPUT must be passed to Synth.start() or Synth.startEngine().

If your computer does not support "full duplex" operation, then it cannot record and playback simultaneously. In that case, you must also specify Synth.FLAG_DISABLE_OUTPUT to allow "half duplex" operation. Many older PC cards such SoundBlaster AWE32 and AEW64 are only half duplex. Most of the newer PCI bus soundcards, such as SoundBlaster Live, are full duplex.
