Detailed Description

Constructor & Destructor Documentation

SoundManager::SoundManager	(	ConfigObject< ConfigValue > *	pConfig,
		EngineMaster *	pMaster
	)

Initializes Mixxx's audio core

Parameters:

pConfig	The config key table
pMaster	A pointer to the audio engine's mastering class.

Here is the call graph for this function:

SoundManager::~SoundManager ( )

Destructor for the SoundManager class. Closes all the devices, cleans up their pointers and terminates PortAudio.

void SoundManager::checkConfig ( )

Here is the caller graph for this function:

void SoundManager::clearDeviceList ( )

Closes all the devices and empties the list of devices we have.

Here is the call graph for this function:

Here is the caller graph for this function:

void SoundManager::closeDevices ( )

Closes all the open sound devices.

Because multiple soundcards might be open, this member function simply runs through the list of all known soundcards (from PortAudio) and attempts to close them all. Closing a soundcard that isn't open is safe.

Here is the caller graph for this function:

QList< SoundDevice * > SoundManager::getDeviceList	(	QString	filterAPI,
		bool	bOutputDevices,
		bool	bInputDevices
	)

Returns a list of all the devices we've enumerated through PortAudio.

Parameters:

filterAPI	If filterAPI is the name of an audio API used by PortAudio, this function will only return devices that belong to that API. Otherwise, the list will contain all devices on all PortAudio-supported APIs.
bOutputDevices	If bOutputDevices is true, then devices supporting audio output will be listed.
bInputDevices	If bInputDevices is true, then devices supporting audio input will be listed too.

Here is the call graph for this function:

Here is the caller graph for this function:

const EngineMaster * SoundManager::getEngine ( ) const

Returns a pointer to the EngineMaster instance this SoundManager is using.

Note:: pointer is const at this point because this is only being inserted so that the prefs can find out how many channels there are and I feel uneasy about providing mutable access to the engine. Make it non-const if you end up needing a non-const pointer to the engine where you only have SoundMan.

SoundDevice * SoundManager::getErrorDevice ( ) const

Definition at line 475 of file soundmanager.cpp.

Here is the caller graph for this function:

QList< QString > SoundManager::getHostAPIList ( ) const

Get a list of host APIs supported by PortAudio.

Returns:: The list of audio APIs supported on the current computer.

Definition at line 193 of file soundmanager.cpp.

Here is the caller graph for this function:

QList< unsigned int > SoundManager::getSampleRates ( QString api ) const

Returns a list of samplerates we will attempt to support for a given API.

Parameters:

API	a string describing the API, some APIs support a more limited subset of APIs (for instance, JACK)

Returns:: The list of available samplerates.

Definition at line 281 of file soundmanager.cpp.

Here is the caller graph for this function:

QList< unsigned int > SoundManager::getSampleRates ( ) const

Convenience overload for SoundManager::getSampleRates(QString)

void SoundManager::inputRegistered	(	AudioInput	input,
		AudioDestination *	dest
	)		`[signal]`

Here is the caller graph for this function:

void SoundManager::outputRegistered	(	AudioOutput	output,
		const AudioSource *	src
	)		`[signal]`

Here is the caller graph for this function:

void SoundManager::pushBuffer	(	QList< AudioInput >	inputs,
		short *	inputBuffer,
		unsigned long	iFramesPerBuffer,
		unsigned int	iFrameSize
	)

If the framesize is only 2, then we only have one pair of input channels That means we don't have to do any deinterlacing, and we can pass the audio on to its intended destination.
