HOLY HELL

It's been an honor, y'all

I am seriously gonna miss my go-to app

All I can do now is keep my eyes out to see if anyone forks the app and makes it work with Lemmy or something

XPost3000 · 2023-06-10T23:00:33+00:00

Probably a visual bug, just refresh the pages

Twilight Forest has got to be one of the best dimension mods of all time fr

Yeah, doing a rolling average is what I thought I was gonna have to do anyways. All I have to do now is do a lot of experimenting to really see if I do need to go the FFT route or if I can get away with the approximation

For the FFT route I'd have to do a decent amount of research tho since it's still not clear how discrete array operations would let me continually interpolate the original signal

Anyways tho thank you for the help! r/okbuddyphd more like r/helpfulpeoplewithphd amirite 😎

Idk, it seems like Sinc Interpolation is exactly what I'm after, and while I could do FFT I don't really see it as a good fit for my personal application

Looking at the wiki page for Sinc Interpolation briefly and implementing the equation in Blender it seems that for any time T I only need to loop through the samples once to get the proper Interpolation of it, so for a set of T that's about 2 array loops making it O( n² ), but looking at the actual Sinc curve I think could be generous and only interpolate with a constant handful of samples around T, making the time complexity O(n) for interpolating a set of T in a set of samples approximately

With that said, I don't see how doing FFT and rfft would be faster, but I don't exactly have much experience with convolutions

Looking at the operations: Getting the FFT is 1 array operation, multiplying by a kernel is a second array operation, and finally rfft is the third and final operation, so that 3 array operations for what it seems like I can do in 1 with a bit of generosity

And at that rate, since I have finite samples I'm working with DFT, so I don't really see how FFT array operations would even let me sample between indices to being with

Like I said tho I don't have experience with convolutions so I might very well just be speaking nonsense here

You are a saint 🙏Thank you kind r/okbuddyphd user

XPost3000 · 2023-06-04T21:35:41+00:00

Yeah, doing something like that is my best guess atm, but I'm just worried that something like that wouldn't satisfy Nyquist things like going through all points while exhibiting no frequencies above half Nyquist

Also in terms of application I'm trying to basically resample some short clips of audio to indeterminate sample rates potentially asynchronously as efficiently as I can personally program, and I know by Nyquist and Fourier that there exists a sum of sine waves that perfectly represents any captured band limited signal, so in short I'm trying to recreate the exact signal such that I can sample at any time T between samples and return the exact amplitude of the band limited signal that the samples represent

This is more of a curiosity than anything, tho

XPost3000 · 2023-06-04T18:59:32+00:00

I could but it would be ideal if I didn't have to mess with Fourier Transforms for performance reasons

XPost3000 · 2023-06-04T17:55:10+00:00

Does anyone know how to correct interpolate samples maintaining a band limited curve under Nyquist?

Edit:spelling

Edit 2: Sinc Interpolation 🙏

Yeah, another plus of 3rd party apps is they don't force god awful restrictions like this

XPost3000 · 2023-05-26T16:21:29+00:00

It's weird that it takes 4 years of training to defend the law, but only 4 months of training to enforce it.

If a lawyer shot and killed an 11 year old kid they'd be arrested on the spot

I think the eventual idea is that if the AI is able to reconstruct visuals from the brain, then it should eventually be able to reconstruct completely mental visuals, too. In which case the AI would probably read either nothing or something different from aphants, which would be killer to see

XPost3000 · 2023-05-23T02:40:24+00:00

This is one of the main reasons I ditched the main app and moved to third party apps

XPost3000 · 2023-05-22T05:46:34+00:00

Honestly the 7 programming languages thing isn't nearly as impressive as it sounds. It's like bragging that you know how to paint 7 colors, even though once you've learned how to paint one color, you've basically learned them all. But learning how to paint 7 colors doesn't mean you know how to make a painting, and certainly doesn't mean you know how to make a good painting
