The 2D Morlet/Gabor filterbank is currently created in the spatial domain and transformed to the spectral domain afterwards. It would be cleaner to construct it in the spectral domain from the start (…

## Describe the question
A clear and concise description of what the question is.
**Summary of work:**
Audio signal is transformed into frames (log-mel-filterbank energies features) with frame widt…

For reproducibility it would be useful to have these two mel filters. These are the two types of filters I have seen the most so correct me if there are other more important types of mel filters.
