Fade in audio

[tobx]

Hello,

I have some experience with rust, but not all that much. It is difficult for me to grasp all of this, so I hope for some help here. My goal is to play and slowly fade in audio (smoothly, sample by sample) for a configurable duration.

So, using symphonia-play as a starting point, is this here the recommended point to hop in and do the fade in calculations:

But how can I get the actual samples from decoded to do the math with?
