• positional audio

• configurable upon init

• no obvious exposure for movement of sound

• orientation was flipped (up vector should match voxel’s coord system)

VOXEL-AUDIO FORKHTTPS://GITHUB.COM/JANDET/VOXEL-AUDIO/TREE/INTERACTIVE

• moveTo method to alter position upon avatar update

• orientation up vector fix (0, -1, 0) to (0, 1, 0)

• spec and compatibility updates

• make Gain configurable

NICE TO HAVE:

• exposure of raw node and context would enable more complex audio graph building

• auto bind position to voxel item w/ listeners on position movement

POSITIONAL-AUDIOHTTPS://NPMJS.ORG/PACKAGE/POSITIONAL-AUDIO

• Wrappers to make working with audio graphs and nodes easier (2D)

• Context

• Panning Sound

• Listener

• Directional Mixin

FUTURE IDEAS:

• Incorporate 3D properly

• Environmental convolution

• More clear how to build custom audio graphs upon it

• Format for transitioning “sheet music” to web audio nodes
