Speaker definition object holds the information of speaker setup. This object is currently only used for vbap but this can be theoretically used also by the hoa-light object

Add support to zirk_id for polar positions: azimuth (0 - 360, -180 - 180, etc) & elevation (0 - 90).

The main server patch zirkonium_server.pd should be modularized by:

• setting clone numbers via creation arguments, ie. [zirkonium_server 16 16 32] could create a server with 32 IDs, 16 inputs, 16 outputs, etc
• moving #zirk-in and #zirk-out messaging into a wrapper patch
• adding a help file for documentation & testing
• testing

IO

• The pd object should have 4 inlets
• The pd object should have 1 outlet

Type

• The pd object is not a DSP object

Inlet

• The first inlet accepts bang / message
• When the first inlet receives a message, starting with "define_loudspeakers" the object interprets the message as a speaker definition formatted in the style of VBAP object and store the data internally
• The second inlet accepts float and it lets the user control the azimuth of the source (-180 ~ 180)
• The third inlet accepts float and it lets the user control the elevation of the source (0 ~ 90)
• The fourth inlet accepts float and it lets the user control the spread (0 ~ 100)

processing

• The pd object internally encodes/decodes higher-order ambisonics using HOA-light library and output the volumes of each speaker when the first inlet receives a bang

order

• The order of ambisonics is defined by the number of speakers automatically
