Detailed Description

A mixer.

Take n input signals and output the wieghted sum of the signals using the "gain_*" inputs.

Parameters

[in]	signal_i	The ith signal
[in]	gain_i	The ith gain
[out]	signal	The output

Constructor & Destructor Documentation

Mixer()

yase::Mixer::Mixer

(

int

n

)

Construct a new mixer.

Parameters

n	The number of signals to mix

Member Function Documentation

get_amplitude_input()

double yase::Mixer::get_amplitude_input

(

int

i

)

The integer index of the gain input for the signal input i. If there are n inputs to the module, then "gain_i" is signal number n+i.

Parameters

i	The index of the input

init()

void yase::Mixer::init ( )

virtual

This method should be overridden by derived classes. It will usually be called once, after all modules and connections objects have been added to a synthesizer, but before the synthesizer starts running.

Implements yase::Module.

set_amplitude_input()

void yase::Mixer::set_amplitude_input	(	int	i,
		double	value
	)

Set the gain of input i to value. This method is faster than set_input("gain_i"), which should only be used during setup.

Parameters

i	The index of the input
value	The value to set the gain to

update()

void yase::Mixer::update ( )

virtual

This method should be overridden by derived classes. It will be called repeatedly by a synthesizer at a frequency determined by SAMPLE_RATE.

Implements yase::Module.
