Question regarding filter bank

[evaldsurtans]

Great job on implementing paper!

Question: why did you use python_speech_features.fbank instead of librosa.feature.melspectrogram ?
Both transformations are the same, right?

[onceforall]

they are almost same except the fbank discards the IDFT procedure.so it can maintain more source info of the audio.

Thank you for answering, I suspect that you mistaken melspectrogram/filterbank for MFCC. Because as far as I understand you use IDFT only for MFCC. So python_speech_features.fbank should be the same as librosa.feature.melspectrogram right?
