Should clones be able to start their own copy of a sound?

[ericrosenbaum]

This PR, “Audio effects state for clones,” introduced a new behavior that need discussion and possible changes.

It is related to the behavior of a clone starting a sound when another clone or the parent sprite has already started that same sound. In 2.0, the sound restarts. After the above PR, a new copy of the sound starts playing (with the clone's effects settings applied).

Example:
If you have a sprite with the sound "happy song", and you run "forever [start sound happy song]", it will restart the sound every frame, creating a stuttering sound. This is true in both 2.0 and 3.0. However, in 3.0, if you create a bunch of clones, and run "when I start as a clone [start happy song]", the clones will all separately start their own copy of the song.

Upside: you can make music using clones that play the same sound at overlapping times with different audio effect settings (pitch, pan, volume).

Downside: you get a potentially very loud sound instead of a stuttering sound if you make a lot of clones that play a sound simultaneously.

We should consider how often this downside case would occur in existing projects, if possible.

I'd say that the old behavior is less intuitive, since why would all clones share one speaker?

Discussed! @ericrosenbaum will follow-up with changes. :-)
