4. VOXEL-AUDIO FORK

• 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

5. POSITIONAL-AUDIO
HTTPS://NPMJS.ORG/PACKAGE/POSITIONAL-AUDIO
•
Wrappers to make working
with audio graphs and nodes
easier (2D)
FUTURE IDEAS:
•
Incorporate 3D properly
Context
•
Environmental convolution
•
Panning Sound
•
More clear how to build
custom audio graphs upon it
•
Listener
•
•
Directional Mixin
Format for transitioning
“sheet music” to web audio
nodes
•
