Hoa Library (A high order ambisonics library) for Faust

Version :

Hoa.lib 1.3 for Faust (Download). The hoa.lib file contains the high order ambisonics functions in FAUST. This version isn't included in the Faust distribution (for now). Home of the project : https://framagit.org/wargreen/hoalibrary-faust

Functions :

  • encoder : encodes a signal in the circular harmonics domain depending on an order of decomposition and an angle.

  • decoder : decodes an ambisonics sound field for a circular array of loudspeakers.

  • decoderStereo : decodes an ambisonic sound field for stereophonic configuration.

  • optimBasic, optimMaxRe, optimInPhase : weights the circular harmonics signals depending to the ambisonics optimization. It can be "basic" for no optimization, "maxRe" or "inPhase".

  • wider : can be used to wide the diffusion of a localised sound. The order depending signals are weighted and appear in a logarithmic way to have linear changes.

  • map : encodes a source with distance compensation.

  • rotate : applies a rotation of the sound field.

  • encoder3D : encodes a signal in the 3D circular harmonics domain depending on an order of decomposition and two angle.

  • optimBasic3D, optimMaxRe3D, optimInPhase3D : weights the 3D circular harmonics signals depending to the ambisonics optimization. It can be "basic" for no optimization, "maxRe" or "inPhase".
