Public Member Functions
	Microphone (Robot *owner, Vector micRelPos, double range, MicrophoneResponseModel micModel, unsigned channels)
	Constructor e.g.
	~Microphone (void)
	Destructor.
void	init ()
	Reset distance values, called every w->step().
virtual void	objectStep (double dt, PhysicalObject *po, World *w)
	Check for local interactions with other physical objects.
void	resetSound (void)
	Reset sound buffer to 0 after one time-step in experiment.
double *	getAcquiredSound (void)
	Return frequencies of input sound.
void	getMaxChannel (double *intensity, int *channel)

Vector	getMicAbsPos ()
	Get absolute position of microphone.
Protected Attributes
PhysicalObject *	owner
	Robot/object with the microphone.
Vector	micAbsPos

Constructor & Destructor Documentation

Enki::Microphone::Microphone	(	Robot *	owner,
		Vector	micRelPos,
		double	range,
		MicrophoneResponseModel	micModel,
		unsigned	channels
	)

Constructor e.g.

: Microphone(this, Vector(0.5, 0.5), 5, micStepModel, 20); meaning: the mic is (0.5, 0.5) away from robot center, can hear sounds up to 5 units away, uses a step model to detect sounds and can distinguish 20 frequencies
