About spec_augment

[ChristopheZhao]

hi,I have a little question about the function of spec_augment in data_gen.py

I noticed that before call this function,call the function of extract_feature,the last part of this function,Exchange of dimension of feature.

and i read code of you reference:

before call spec_augment,it transpose the dimension of features.but the the order of (all_frames_num, all_freqs_num) different as your's.
IIs there something wrong with my understanding somewhere?

and the same effect between np.swapaxes and np.transpose to a 2d array.
