Are we extracting a constant value (in the same index within "audio") as the target y-value?

y_cur = audio[receptive_field_size]

Hi, I am a grad student at Georgia Tech, trying to learn WaveNet through your implementation. Thanks for building this. I have a question though: why is this line extracting y_cur like this? If you always extract "receptive_field_size" index from "audio," we would be extracting the same y-value for every audio segment in X. I was wondering if this is the intention?
