1. add simple fade when volume.
2. do fade when adjust volume to maximal.
when to adjust volume we hope that the audio sample is smooth
we need to calculate the gradient step between each sample based
on the total change of the gradient (i.e. dst_volume - src_volume)
and the number of samples (nb_samples) and apply it to the target
sample.
I don't understand this. Why would you want any fading when you
want to
apply the audio gain uniformly over the whole duration of audio?
It is useful to transition into the new volume level.
The afade filter (or combining volume with afade) can already support
such a use case, no?
afade only fades from/to 0.
And it only operates at stream boundaries, but the volume filter
supports timeline 'enable' for mid-stream changes.
