@loopzy the number 3 comes from the calculation of RNN. You can see the following image about how torch.nn.LSTMCell is calculated.
where x is calculated by three matrix, Wii, Wif, Wig,which can fused together.
That makes the number 3.
from lyra.
@loopzy, kernel_size = 3 means that the first conv1d layer looks at 3 logmel frames: 1 logmel frame in the future (a frame look-ahead), 1 frame in the present and 1 frame in the past.
RNN layer takes 1 feature vector each time but this feature vector can be computed from 1 logmel frame look ahead and many frames at present and in the past

Thanks! I guessed that too. But in that way, the 3*1024 vector is a combination of 3 copies of 1024 vector and I am not sure.
Also, it is strange that he first conv1d of conditioning stack has kernel_size=3 while the model accepts only one logmel feature in each time. Do you have any ideas about that?

Thanks a lot!
