Training with raw un-normalized mel features was resulting in a clean synthesis

[berger-ulak]

Hello all,
In this answer @sharathadavanne suggests to train waveglow model with raw un-normalized mel features. Can someone explain what does it mean?

Do we need to un-normalize wav files or is there any parameter in settings?

Hi @berger-ulak go ahead and use the waveglow code as it is. It works perfectly fine.

In the issue you tagged, I was trying to improve the wavegan performance by using normalized features, which did not help me.

@sharathadavanne , thank you sir!
