Half the fun of this project has been doing it in Python and performance hasn't been an issue so far, which says something about how fast Python is already. And indeed native would be ~50x-100x faster.

I must defend the design choice for the dictionary of arrays though, this has been a very conscious choice:

  - The "dictionary-of-arrays" approach allows lookups in constant time O(1), irrespectively of how much data has already been stored (compared to one big array)
  - The dictionary structure allows me to throw away data in the middle easily (without having to handle growing arrays), because the "dictionary-of-arrays" has already been chunked. The audio looper will use only some parts of the recorded audio, leaving big parts in between unused.
