Ok, good to know.

So that basically means we’re looking at:  
[audio]-\>[descriptor(s)]-\>[weighting]-\>[stats]-\>[flatten]-\>[prune]-\>[standardize]-\>[pca]-\>[(merge with others)]-\>[normalize]-\>[_ **query/whatever** _]  
?

It was just that. Thankfully all the `clue`s helped, but it was tricky to follow since things jumped around and were reused in places. Plus all the `;notation` too!

Is this in response to the weighing (weighting? (actually, are we using weight/weighing to mean two separate things now? (e.g. loudness-weighted descriptors vs weighing parameters in a query))) question or to the normalization stuff, or just a general comment?
