Why are you using "use_mel_posterior_encoder"?

Hi I'm sungwoo Moon. First of all, thank you for your sharing your code.

I'm looking at your code and I'm wondering why you use 'use_mel_posterior_encoder'. In the paper vits1, it says that we use spectrogram like vits1, but I wonder if there is a difference in TTS performance.

Thank you.
