New "neural" voices (text to speech) - Low volume / different EQ and poor quality compared to previous voices

Hi Jose, thanks a lot for your reply!

To revert STORYLINE to the older version for skip the problem, in my opinion doesn't look good.. Possible to introduce both version of voices in different menu? In this case an user can choose what you need.

But really what is the advantage/benefit offered by the new "neural" voices? I have done some test and I am not so satisfy, mainly for the question of low volume and for the quality as well. 

For the matter of videos your suggestion is to re-encode with Handbrake? Will do cause I normally use it mainly to resize videos. Anyway I will be back to you asap.

An additional question for you, I have done  a lot of project by facing same problem related to audio quality. It seems during the preview the background music/music embedded in the videos sounds in stereo, as expected, by after a project has been published the general sounds are in MONO... Possible? 

I have done tons of experiment and also changed all settings available as well without the video compression, without find any solution for this... 
Could you please help me?

Thanks in advance!!
Regards
Roberto
