Matrixn, it also is the only object that demands significant computational facilities. The only MSP object in VBAP implementation is Type can be smooth (linear cross fading) or fast (no Number of outputs, type of cross fading and the length The parameters are the number of inputs, the Object dac performs the digital-to-analog conversion. Signals to compensate different loudspeaker distances. The object Is_ delays is used to delay the loudspeaker It outputs each audio signal to each loudspeaker channel gained with corresponding gain factor. It receives audio signals from MSP object(s) and gain factors from vbap object(s), see Fig. The matrix- object performs the panning process MDAP and outputs the gain factors for all loudspeakerįigure 7: Panning directions used in 3-D spreading. Receives a bang, it performs calculations of VBAP and It takesĪs input the loudspeaker setup data from object define_loudspeakers, panning angle as azimuth and elevation parameters, and a parameter that controls The vbap object calculates gain factors depending on specified panning direction and on received The loudspeaker directionsĪre presented in order of the loudspeaker channel numbers. If the dimensionality is 3,įollowing number pairs are (azimuth, elevation) coordinates of the loudspeakers. If the dimensionality is 2, the following entries are the azimuthĪngles of the loudspeakers. The first parameter is the dimensionality of the When the parameter has valueġ00, the gain factors of all loudspeakers have nearlyįigure 4: The loudspeaker configuration is specified in define loudspeakers object.
In addition, when the value of the spreading parameter exceeds 70, the gain factors of all loudspeakers are faded in. The spreading parameter is equal to 7 value used Panning direction and the partial panning directions.įigure 6: Panning directions used in 2-D spreading.
The variable 7 presents the largest angle between actual In 2-D setups the number of panning directions isħ and in 3-D setups the number is 17, the layouts of directions are presented in Figs. Used if the user wants to select the triangles by hand. Read the loudspeaker configuration as a list and read It performs theseĬalculations when it receives a bang message. Outputs the matrices and the loudspeaker numbers ItĬhooses loudspeaker pairs or triplets and calculatesĪn inverse matrix L-1k for all of selected triplets. It is initializedīy specifying the directions of the loudspeakers. Needed calculations to form a data set that describes
