zirkoniumspatializationserver's Issues

implementing hoa-light object

Name

hoalight

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

server patch modularization

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

hoa-light object share the speaker definition

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

zirk_id: polar positions

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