How to embedding audio stream data to k-vector (512)

[buaapengbo]

Hi, thank you for open source it !

I read your paper and tests/integration_test.py , my question is that I want to know the way you use, to embedding the audio stream data with D = 512.
Actually it's like the question here
The way you generate train data or test data from a audio stream.

Is that like librosa.feature.mfcc(y=X, sr=sample_rate, n_mfcc=40) ?
In your paper, say:
In this system, audio signals are first transformed into frames of width 25ms and step 10ms, and log-mel-filterbank energies of dimension 40 are extracted from each frame as the network input. These frames form overlapping sliding windows of a fixed length, on which we run the LSTM network. The last-frame output of the LSTM is then used as the d-vector representation of this sliding window
How can I reproduce this part ~

I appreciate it, waiting for your response!
Thanks,
Bo
