Porcupine accepts single channel, 16-bit PCM audio. Now the handle can be used to monitor incoming audio stream. A higher sensitivity reduces miss rate (false reject rate) at cost of increased false alarm rate. Sensitivity is the parameter that enables developers to trade miss rate for false alarm.
