Member Function Documentation

void SpeakerLayout::readSpeakerFile ( const char *  filePath)
inherited

Reads the speaker listing file according to the specification.

SpeakerLayout * SpeakerLayout::defaultSpeakerLayout ( )
staticinherited

Returns a pointer to the default layout. If no default exists, it creates one.

Returns a reference to the default layout. If no layout has been set, it creates a stereo speaker layout.

void SpeakerLayout::setDefaultSpeakerLayout ( SpeakerLayout defaultLayout)
staticinherited

Use it to set a layout as default. Clients (e.g. a Panner) can then make use of this layout.

The default speaker layout is used by Panners, when not specified otherwise. If using multiple Panners, but only one speaker setup, is best to set the layout as default, and then forget about that; Panners will know to use such layout.

Note
As a suggestion, set the default layout before creating any Panners. Otherwise they'll have to rebuild their data.

void SpeakerLayout::addSpeaker ( float  azimuth,
float  elevation = 0.0,
float  radius = 1.0 
)
inherited

Add a speaker specifying its position in degrees from the center of the listening space.

Add a speaker to the layout. Parameters should be specified in degrees.

void SpeakerLayout::addSpeaker ( float  x,
float  y,
float  z,
float  xNorm,
float  yNorm,
float  zNorm,
float  gain 
)
inherited

Add a WFS speaker.

Add a speaker to the layout. Parameters should be specified in x,y,z.

Definition at line 164 of file SpeakerLayout.cpp.

References csl::Model::changed(), and csl::SpeakerLayout::mSpeakers.

void SpeakerLayout::normalizeSpeakerDistances ( float  radius = 0)
inherited

Returns the number of loudspeakers in the layout.

When speakers are not placed at the same distance from the "sweet spot" (the center of the listening space) it's common to assume they are at a fixed distance by setting all of them as if they were, and then the output data is delayed to compensate for this difference. See: ActiveSpeakerLayout.

Sets speaker distances to a fixed distance from the center of the listening space.

Parameters
radiusis optional. If not set, it finds the best radius by analyzing the layout.

If any of the speakers in the layout has an elevation other than 0, it returns true.

Prints the number of speakers in the layout and their position.
