Over the Frail Dream

yeah one way of thinking about the DFT on an N-sample window/signal is it does N filters independently and the FFT is an optimisation that reduces a lot of redundant work between the filters. filters is a pretty broad term but for linear filters and dsp and stuff this isn't an analogy and is exactly ...

so glad you asked

theres two ways to understand fourier transforms. one understanding starts with the continuous + calculus and the other with the discrete + linear algebra. they both end up at the same place. on the linear algebra it makes sense to talk about dimensions; its the number of ...

for the actual syncing i don't and just assume onset strengths are good enough. hmm having ideas again

for the DFT thing it doesn't matter. it'll just extract whatever periodicity is there. that'll tell you if a rhythm at whatever bpm is present in the onsets you have. so really any kind of ...

an easy example of musical stress and onset strength not aligning is _234_234_234_234. you hear the gap as the beat

that's assuming the onset strengths are reliable indicators of what people hear as musical stress, which, since it fails to fire at all on some material you can easily hear drums in ...

that does not inspire confidence!

mine also has the 1.5x problem but you can detect it somewhat reliably if the onsets strengths follow the music stress by looking at the DFT of the onset times (when you only care about a couple frequencies you don't have to do a full FFT)

btw when i say this shit does it make sense to anybody

yeah it's like. convenient for serialisation. otherwise it has zero merits

the way to think about it is there are multiple equivalent ways to represent a chart and converting between them is extremely cheap. so whatever edit you are doing to a file you want to do it in whatever representation is ...

holy shit my mind just opened

had you started down the road of trying to do everything in row space all the time

fixed rmb + d/del to delete on drag + drag from any beat line + fixed catbox nuking the zip contents

i remember implementing the rmb cancel so idk whats going on there

i implemented rmb canceling on the release branch. the beta branch of AV is ignoring all right clicks
