Detailed Description

This class implements the mixer.

Constructor & Destructor Documentation

Mixer::Mixer ( EventContext *  context )

inline

Create a new mixer.

Parameters

context

event context

Member Function Documentation

void Mixer::addSid

(

sidemu *

chip

)

Add a SID to the mixer.

Parameters

chip	the sid emu to add

void Mixer::begin	(	short *	buffer,
		uint_least32_t	count
	)

Prepare for mixing cycle.

Parameters

buffer	output buffer
count	size of the buffer in samples

void Mixer::clearSids

(

)

Remove all SIDs from the mixer.

void Mixer::event ( )

virtual

Timer ticking event.

Implements Event.

sidemu* Mixer::getSid ( unsigned int  i ) const

inline

Get a SID to the mixer.

Parameters

i	the number of the SID to get

Returns

a pointer to the requested sid emu or 0 if not found

bool Mixer::notFinished ( ) const

inline

Check if the buffer have been filled.

void Mixer::reset

(

)

Schedule mixer event.

uint_least32_t Mixer::samplesGenerated ( ) const

inline

Get the number of samples generated up to now.

bool Mixer::setFastForward

(

int

ff

)

Set the fast forward ratio.

Parameters

ff	the fast forward ratio, from 1 to 32

Returns

true if parameter is valid, false otherwise

void Mixer::setStereo

(

bool

stereo

)

Set mixing mode.

Parameters

stereo

true for stereo mode, false for mono

void Mixer::setVolume	(	int_least32_t	left,
		int_least32_t	right
	)

Set mixing volumes, from 0 to VOLUME_MAX.

Parameters

left	volume for left or mono channel
right	volume for right channel in stereo mode

Member Data Documentation

const int_least32_t Mixer::VOLUME_MAX = 1024

static
