Title: [SOLVED] Getting the actual volume of a sound/music
Post by: WilliamKappler on September 17, 2021, 02:04:13 am

I have a use where I need to know the actual, post-attenuation (for 3D sounds) volume of sounds/music. It seems that, according to the API docs, there is no such function; there are only ways to get the various parameters that determine the attenuated volume. Is there some functionality I am missing to get the actual volume, post attenuation?

For instance, I set the sound volume to 0.5, but it's attenuated to half of that based on distance, I would want to know it is now 0.25.

The way the sound is attenuated is documented and I could reproduce it on my program's end, but it would of course be better if I could just ask SFML. That would cover the possibility of the formula changing in the future.

There's no way to retrieve it.
SFML uses OpenAL underneath which will do the calculation. Not sure if OpenAL even reports the current "volume".

Understandable. I'll just use that formula to get (approximate?) it on my end. Should be good enough. Thanks!
