Question about calc_spectrograms

[linzwatt]

Hey, sorry to open this as an issue, but I was wondering why the complex procedure to create the Mel Spectrograms?
Pytorch has torch.stft and there is also torchaudio with Spectrogram and MelSpectrogram transforms

I understand this is a direct translation from tensorflow, but I wanted to know if you knew of any reason why the 'manual' process to compute STFTs ?

Actually，I don't consider too much when I upload this code, but I think there is a little difference between the two methods, maybe you will find the detail at Appendix D of the raw papaer https://arxiv.org/abs/2008.01160
