miku & rin coz they're cute

I'd get Miku and Luka (takoluka edition).

Miku and Luka, entirely because I don't like the Future Rin design much.

If it was regular Rin, it'd be perfect, and thus I would pick Miku and Rin.

ZOMG

y-you got taiga making chocolate for you!?!?

also.. happyy easter!

!

Plain characters like me are only good enough for cloned manko... Fine, I'll have sex with teh Rei!

she's older than you sick fuck

AAAAAAHHHHHHHHHH WTF IS THAT

what is my waifu doing here????

I could not ヽ(;´Д`)ノ

YURI POWAR!!!

I wish I was as interested in anything as OP is in whatever he's talking about

Well actually I'm implementing the techniques that were used for VOCALOID2. But a VOCALOID1-like engine could be an interesting future project.

sorry

Hello I'm back with another update to my VOCALOID project. It's not as big an improvement as last time - and in fact, there's no new features - but I felt like it was worth posting. I've been trying to rectify the major issues before I move onto implementing the Excitation plus Resonance model.

The first thing I attempted to tackle was all the added noise at high frequencies.
Here's the original spectrum: https://files.catbox.moe/fq55bo.png
And here's the reconstructed spectrum (with no transforms applied): https://files.catbox.moe/gq7jff.png
You can clearly see the high frequency artifacts. The first thing I tried was something mentioned in the paper. In the paper, specifically the WBVPM section, it was mentioned that there are two approaches for a non-integer size discrete fourier transform. The first one is repeating the signal while second is upsampling it. I went with second as the former is patented and also because the second is easier to implement. It is mentioned that increasing the repetition count of the signal (or in the case of upsampling, the upsampling factor), and then discarding the higher frequencies, can improve the estimation by reducing artifacts. In the case of repetition, it is also mentioned that quadratic interpolation can be used in the resulting spectrum, however I am not sure if this can be done for upsampling and as such, I have not tried to implement it for now.

Here's the result after applying an upsampling factor of 3: https://files.catbox.moe/qcgnzq.png
Here's the original audio: https://files.catbox.moe/f7g8ta.wav
The original reconstruction: https://files.catbox.moe/da0m1i.wav
And now with the improved reconstruction: https://files.catbox.moe/513ycn.wav
You can see an improvement, especially at lower frequency, however the high frequency artifacts largely persist. So they have to be arising elsewhere. I realized the source was the reconstruction of the signal (AKA the "synthesis"). I had previously implemented a synthesis method that was quite different from the one used in the study, because I did not understand the method in the study at first. My synthesis method worked by taking each voice pulse and for each sample where the voice pulse is the closest voice pulse to that sample, setting the value of that sample to the interpolated value of a spline representing a time domain version of the upsampled voice pulse with a step corrospondin between the ratio a sample in the regular time domain and the upsampled time domain. Now, in some cases, estimation inaccuracies and differences from any transformations that were applied result in these regions of samples being bigger than the actual sample itself. In these cases, we take advantage of the period nature of the voice pulse and repeat it (i.e. sampling before the start is equivalent from that offset from the end, and sampling after the end is the same as that offset from the start). However, this method results in discontinuities in some cases.
Here is an example of such a discontinuity: https://files.catbox.moe/jnnxfj.png
I began to try to implement an interpolation system. In this system, we could calculate the gap between pulses - or in the cases of inaccuracies in the other direction (i.e. overlapping pulses) - the overlapping area, and interpolate between one pulse and the other linearly. However, this was approach was complicated significantly by the non-integer (and potentially differing) sizes of the pulses as well as numerous edge cases. For this reason, I struggled to do so and spent over an hour trying to figure out how to do it corrrectly. About half way through, I decided to check the paper again and this time I understood the actual synthesis method properly, largely because of a diagram I had missed the first time.
In the actual method, each pulse is is expanded in a manner similar to that of the border interpolation technique used in WBVPM analysis, except kind of in reverse. In this technique, for each voice pulse, we generate extensions on both sides with each extension having the size of the border interpolation ratio of the size of the voice pulse. Then we apply a trapezoidal window to the voice pulse which starts at zero at each side of the extended voice pulse and becomes 1 on either side after protrusion of twice the border interpolation size on each side. Then we overlap and add the voice pulses.
This technique fixes the discontinuity issue because it effectively results in each border-interpolation-length side of each voice pulse being interpolated with the corrosponding section for the other voice pulse linearly over a period of twice the border interpolation size. However, this only holds perfectly when the fundamental frequency is the same for both voice pulses (and thus they are the same size) and they are spaced out at onsets that are exactly the period of the fundamental frequency apart. However, when this in not the case, some amount of modulation occurs that results in some voice pulses being attenuated while others are accentuated. This is especially noticeable when there are large inaccuracies in the fundamental frequency estimation and/or the voice pulse onset sequence.
Here's the same section from before. Notice how now it does not have a discontinuity: https://files.catbox.moe/p26914.png
Now here's a zoomed-out version: https://files.catbox.moe/zacw8w.png
Now here's a section with large inaccuracies in the MFPA estimation that clearly shows large modulation artifacting: https://files.catbox.moe/efk1vx.png
Here's the new spectrum: https://files.catbox.moe/f94zse.png
You can see that while the high frequency artifacts are now gone, there are now more low frequency artifacts. In fact, the overall amount of artifacts is actually higher than before.
Here's the reconstructed audio: https://files.catbox.moe/ympfi0.wav
While I ended out solving this issue by fixing large inaccuracies in the MFPA system, it is interesting to note that my approach is more resilient to estimation inaccuracies. Perhaps for a future improved vocal synthesizer, it would be worth exploring a variant of my periodic continuation technique adapted with an interpolation method that could handle changes in pulse onset and f0.

The first thing I tried was switching to a magnitude-limited logarithmic scale for the ampltiude in the MFPA function instead of it being linear. However, this resulted in little to no effect. The next thing I tried was adjusting the size in periods of the window used for the peaks that are fed into MFPA, however again this resulted in little to no effect. Next, I tried implementing the harmonic peak selection algorithm I proposed in the previous post, but again this resulted in little to no effect.

Same, I use them as the emoji font on my computer. The blobs were cute.
Although I tend to use emoticons when I just want something simple like :) or :D

OP here.
Everything Ive said is of course alterable by those who can code the thing.
But to centralize the point, the main concept of the site is exactly inverse to everything else thats available today that a person can signup and then say whatever they want to whoever they want at any place (threads) they want. No, mine is everything is closed off from you by default. You can sense they are there (imagine faint blurred pixels), but you can't access them yet.

Anyway, to acutize the vision of some possible concepts..
- User grinds Words and Length of posts. Basically like the words per post in twitter or chans, user starts limited, and grow from there
- In the beginning there are only few 'Boards' one can travel in. Perhaps maybe one, 'Home Board' if you will, and boards have relative distances, thus it's easier to get to /sci/ from /x/ than to /mu/.
- At first user will only see what's happening on that particular day, and as time goes on, user will be able to see yesterday's posts, then 3 days earlier, then 2 weeks earlier, this goes on until even years earlier.
- There are no banning because of insulting words. Bad Words are basically privilege, those who got it are actually Frequent Timespender of the site, thats how they got them in the first place. The earned it. Racial slurs are RARE shiny pokemons, the mechanisms of getting this is unknown, but users understand that only someone who spends a lot of time on the site only finds them.
This mechanism avoids the whole concept of mods keeping a website altogether, there's no need, "if you want to evilpost, spend more time in the site and earn it first".
- No such thing as microtransaction shit. Money ruins things. le 4ch's vip pass is part of the downfall.
- Everything depends on Spent Time. Thus in the website Oldfags always have the best privileges.
- The whole Party system does feel hazy to me at this time. As time goes on, you stumble onto other individuals, and you understand because they're like you, they're of course part of some other party too. The Part is probably a removable concept; Im thinking because this World is "Total Limitation by Default at the Start", the amount of people you get to see are very limited at the start, but maybe they dont have to be "party". Maybe it could be a thread youre stuck with. or a 'place', whatever that is. But point is, you're stuck, and you work your way out.
But another point of this feature is I want a kinda forced socialization. Like how "you're good friends with th
