ZeroPadding1D at the ds2_gru_model

[Edresson]

Hi, I don't understand, because you use ZeroPadding1D in this model. you are adding 2048 zeros in the second shape dimension. example: when input shape is: (1,280,161) after pass in the ZeroPadding1D layer the output is (1,2328,161).

Do you want to keep the sequence fixed in 2048? if yes, is it necessary to calculate the number of zeros required for each of the inputs?

Thank you for your response.
