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 ...

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 ...

i was about to add a bit here about why the DFT picks that out but i decided against it. the first book i read on the FFT was julius o smiths and he begins it by being all, okay, imagine a 3d vector, okay, now, imagine a big N-dimensional vector, look, it's so simple! and at the time i was like ...

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

i can understand it fine, except maybe DFT and FFT

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


this would be the most convenient way of doing things, but would also be a hell to implement without some big brain shit, maybe i gotta just suck it up and get utasm working before i go under the bridge ...

holy shit my mind just opened

this would be great and also would remove most of the reason i wanted a beat insertion keybind

Writing an .SM compiler from scratch:

ok now doing some further experimenting, i think maybe it's more learning how to configure it properly using waveform settings.

i wonder if you could throw it into adjust sync with two tabs that let you use fieste's sync or graeme's sync, and i wish i could tell it to use a specific waveform ...

i think this shit is perhaps cooked, especially on this song where it just cannot morally decide if it is syncable (is 192.67 bpm)
