generate_audio questions

Opened this issue · 0 comments

hi,recently, I've been trying different mel preprocessing methods. mel is [-4, 4],audio stays the same(mulaw_encode and mulaw_decode stay the same). But, the generated audio contains a lot of noise, mel is normal.

How can I deal with it? Looking forward for your response, thank you. @bshall
