The V-Chat worlds all automatically play their background sound loops. These were included in the originals as song1.wav and often song2.wav. After trying a few options I settled on using howler.js to play these sounds, which has proven really easy to use and works across every platform I’ve tested it on.
Today I added the original sound effects to the worlds. These are enter.wav and exit.wav, which used to play whenever anyone entered or left the chat room, and collide.wav which played whenever you bumped into the boundary of the world.
The entry and collision sounds react as you’d expect, but since there are no other users present they now play randomly.
I also reduced the volume of the background loops in several of the world, as they can get a little annoying!
