do we need to normalize the data before feeding it to the cnn?

[babaee74]

In case of image we know the maximum is 255 and we normalize it easily. and here the output signal of UrbanDataset is not normalized, is it a good approach to normalize each spectorgram with respect to itself?

if we normalize each audio spectogram based on its max and minimum, we kind of miss the amplitude features, am i right?

Thank you for you answer
