In the current FMOD Studio documentation, one reads this:

“The update thread typically runs every 20ms in its own thread, so the percentage indicates how much of the 20ms is used up.”

Should I assume from this that FMOD typically updates its audio no more than once every 20ms? That it cannot, for example, make two updates which are, say, 3 ms apart?

Related but separate: Is this 20ms update frequency derived from FMOD itself, or is this an observation made by the documentation writer about how game code typically behaves?

This is something that is controlled by the FMOD System, which can also be changed in the [`FMOD_STUDIO_ADVANCEDSETTINGS::studioupdateperiod`](https://fmod.com/resources/documentation-api?version=2.1&page=studio-api-system.html#fmod_studio_advancedsettings).
