Yes, I was able to convert audio to tacotron's mel spectogram and back to audio. I used TacotronSTFT's mel_spectogram function to properly convert the audio into mels. I then used Waveglow to convert it back, although the quality has declined a little bit. Here's how I did it.

def stft_to_tmel(stft):    
    stft = stft.unsqueeze(0)
    stft = torch.autograd.Variable(stft, requires_grad=False)
    
    mel = TacotronSTFT(filter_length=1024,
                                 hop_length=256,
                                 win_length=1024,
                                 sampling_rate=22050,
                                 mel_fmin=0.0, mel_fmax=8000.0).mel_spectrogram(stft)
    mel = torch.squeeze(mel, 0)
    return mel

Hey @jamescasia i've noticed that you just closed the issue: did you find a solution?

Thank you!
