ambiNilla v.3.5

v.3.5 - signal rate version (ambiNilla3~) added

v.3 - 3rd order ambisonic added can switch between 0, 1, 2, and 3rd orders bug fixes

v.2 - 2nd order ambisonic can write raw ambisonic (undecoded) output to file

v.1 - 1st order ambisonic

Notes:

The encoder is derived from this ambisonic panner: https://github.com/cpmpercussion/SimpleAmbisonics/ I streamlined the workflow to support ease of transferring new coefficients to PD, and some math updates. Functions for elevation as well.

Instructions:

• open main.pd and and explore

or:

• Input speaker coordinates in the python script. Generate coefficient list.
• Place it in the 'ambiCoefficients' folder.
• Instantiate an ambiDec abstraction with the first argument as the list name and the second as the number of channels.
• Make sure the channel selector is set to the correct output or add a new channel count for your setup (or delete and remove the switch if not needed).
• Create as many catch~ speaker$1 as needed and route to dac~ 's (16 are included in the example patch).
• Instantiate one or more ambiNilla3 or ambiNilla3~ abstractions. Connect signal input and set the proper azimuth and elevation.
