Great! Refreshing to see a ML post using some well-understood methods instead of throwing a random neural net from Kaggle at the problem...<p>Tangential:<p>> <i>Is a given audio file a sample of a kick drum, snare drum, hi-hat, other percussion, or something else? (...) Humans have no trouble classifying these two sounds, as we’ve likely heard them tens of thousands of times before.</i><p>Are people taught that in schools or something? Because I personally can't classify those sounds, don't know these names, and I'm not sure how I was supposed to learn them, other by playing in a band.
