I'll adapt volume files.

Yes please!

yes please also, i have no idea what or how to make a FOC

[Electro]

{snip}It is for new FOC-stim boxes but if there are users interested to test-drive the normal-box restim version, I'll adapt volume files.{/snip}

I know this was discussed a little bit before, but in general is the FOC stim usually a higher or lower difference in volume range for the same perceived intensity as Stereostim? I can test this out and make my own adjustments and share the volume file, but might not be able to get to it for about a week. If the highest point is 100% on both, would there be a bigger range with FOC or less? I'm asking this because normally I 'close' the gap between top and bottom a bit for most of your stereostim stuff when I adjust volume files and so I'm trying to get a baseline on how far I might want to move the numbers around when I start.

I'll place off topic answer into spoiler

Comparing to stereostim, FOC has much smoother experience, dynamic range (the range of volume you can use) is order of magnitude wider, because it is current-controlled so it doesn't snowball out of control.
What does that mean in practice?
If you have a stereostim, and you set calibration at i.e. 75% level, in one hour you cannot expect to reach 100% without it being too much at some point.
With FOC you can easily start at 50%, and if you go below, i.e. 30%, on stereostim you will usually not feel anything (because voltage-controlled, the current decreases non-linearly), while on FOC you will still feel it at 30%. It is amazing for something like this creation that is supposed to be riding the border between pleasure and pain.

"Conversion" of FOC volume files to stereostim can generally be done by reducing dynamic range (i.e. shifting lowest points up) but that also pulls breaks up, and would pull them up the most, which is not good because here breaks are supposed to reset your desensitization :)

So I have created a python script that only shifts the points above a threshold.
In this case I used it like this

Code: Select all

python .\shift-funscript.py '.\Twisted Tales.volume.funscript' 30 40

This leaves all points at value 30 or below untouched (so breaks are not increased) and reduces distance to max by 40% (so if a dot is at 40, then it will move to 64, but if it is at 90 then it will move to 94 - this is compressing dynamic range making it suitable for stereostim).

Yes please!

yes please

I have created 3 new volume versions, you will find them in the subfolders "ss_mild", "ss_normal" and "ss_spicy" that were created by compressing foc by 60, 40 and 20 percent respectively. I have replaced default ones with these from ss_normal. I'd love to get feedback if that one is good, and if i.e. it should be just a bit more or less spicy I will replace it with shift of 5-10% more or less. If you tell me that spicy is way too spicy, then I will replace it with one that is between current spicy and normal etc.

When you test just calibrate according to text on screen and then see how it goes for you :)

Also, if I get feedback for these so I know which compression % is best for your boxes, I will also create stereostim volumes for other new stuff I am testing at the moment (almost everything in progress is for FOC).

I have also shared my scripts in "tools" folder so you can play and create your owns. For any feedback/questions about it please lets not bring this thread offtopic, write PM or direct on discord.
Thanks!

tl;dr For the edger477 funscripts with Stereostim, normal is probably spicy enough, will test that next time and report back.

I guess since it's off topic because it's about FOC compared to Stereostim, I'll spoiler this to reduce thread muck, but since it's about the creation of funscripts for these two videos and it's not a new release with a highly active thread, I still think it belongs here.

My initial run with spicy is calibrated for the beginning, the lower level stuff still felt low, the edging stuff felt strong until about 3/4 of the way through the funscript when the volume ran too high and nothing felt good anymore because it was too high. So gap between lowest and highest levels is too much, which was more or less what I expected. I took notes on which volume levels felt right and I might just look under the hood at the numbers in OpenFunScripter to get an idea whether mild or normal seems right and then I'll pick one and see where things stand from there.

I think that just means the electrical interpretation is different, with audio devices if you put a normal linear potentiometer instead of an audio specific potentiometer, the first 1/4 turn will be an exponential increase to what seems like 80% when output to speakers in terms of volume increase, it's just the way that audio electronics work. We're not using speakers, but the input levels through an audio amplifier are similar. It seems that when you control current more directly on a linear scale, you'll get what you describe. It's all about how the levels are being handled with the different electronics. If you are seeing the numbers go up higher on the screen compared to the level of perceived output sensation, I could understand why that seems to be smoother as an effect on its own. Of course there are differences that would make FOC better too, but I think it's a combination of those too as well. I'm sure if both were measured to skin(versus a resistor) and the current levels were calibrated out to a similar range that the same current levels would probably feel a similar level of intensity using the same carrier frequencies.

If you have a stereostim, and you set calibration at i.e. 75% level, in one hour you cannot expect to reach 100% without it being too much at some point.

If I'm stimming for an hour and I set up a .5 or .6 per minute volume increase with Stereostim starting at 75%, I'm usually still feeling decent nearing 100%, which is substantially different from using volume funscripts that only touch 90% in the final 5-10 minutes and blast it at the cum sequence.

With FOC you can easily start at 50%, and if you go below, i.e. 30%, on stereostim you will usually not feel anything (because voltage-controlled, the current decreases non-linearly), while on FOC you will still feel it at 30%. It is amazing for something like this creation that is supposed to be riding the border between pleasure and pain.

Again, I think it's because the actual level of current difference between the two levels with FOC is actually a lower difference in current output between the two points relative to how an amplifier behaves compared to how FOC is designed to control current output.

So I have created a python script that only shifts the points above a threshold.
In this case I used it like this

Code: Select all

python .\shift-funscript.py '.\Twisted Tales.volume.funscript' 30 40

This leaves all points at value 30 or below untouched (so breaks are not increased) and reduces distance to max by 40% (so if a dot is at 40, then it will move to 64, but if it is at 90 then it will move to 94 - this is compressing dynamic range making it suitable for stereostim).

Also, if I get feedback for these so I know which compression % is best for your boxes, I will also create stereostim volumes for other new stuff I am testing at the moment (almost everything in progress is for FOC).

This is super helpful, thank you for releasing the tool. Assuming I haven't forgotten how to use python scripts and the compression shift works how I expect it might, I can play with some values and maybe give you a value that seems to work best for Stereostim(or at least for me).
..although if 30% can't be felt even a little bit in the first place, why not zero for every 30% break?

FOC FOC FOC

Spoiler: show

With FOC, the output current is linear with the volume and/or pot position.

With stereostim, the output voltage is linear with the volume.

But skin resistance is not linear, so when you increase the output voltage linearly, the current increases faster than linear. This causes the discrepancy in "dynamic range" between foc and stereostim. This can be corrected by choosing different volume funscripts for foc/stereostim. This should be automated at some point...

The other big factors are that FOC corrects for the phase shift between voltage and current, and stereostim does not. Skin resistance also changes over time, the moisturizer/electrogel needs considerable time to stabilize.

These three factors explain almost all the variance between foc and stereostim sensations.

By the way, subjective intensity is approximately current^2 to current^3. So a small difference in skin resistance makes a big difference in intensity.

I saved all the Twisted Tales scripts for now. Planning on building a FOC stim in the months ahead (once I get some free time on my hands). From everything I read up until now, FOC seems the way to go in the future.

Question is, can we somehow make FOC scripts from stereostim files? There's a plethora of content out there which can't be played with FOC stim right now... It should be possible theoretically, right?

[diglet]

It is theoretically possible, but:

- The FOC only does 3-phase, and there are very few 3-phase creations that are worth converting (imo). I will admit I started coding restim almost immediately after I discovered estim, so I never had the time to build a library of 'old favorites' that I want to replay.
- 'reverse calibrating' the audio files is more an art than a science, so it requires tons of sweat equity to get working.
- edger477 spent a lot of work making funscripts for many of the popular creations, so there already is a ton of content out there.
- creating good stim files with Restim is so much easier than it was, that you will almost certainly be able to create something better than the original with far less effort than what was put in the original.

I think it is an very interesting technological challenge, that is unlikely to be really useful in practice.

If you have specific files you want to replay on the FOC you can always request it, perhaps there is someone that is willing to attempt a manual conversion of your favorites.

On the topic of FOC vs stereostim funscripts.. Perhaps we could try to standardize that "volume.funscript" is designed for stereostim devices, which non-linear volume-intensity relationship, in order to stay consistent with the majority of existing scripts and reduce confusion?

I propose either of the following for scripts that are designed for use with FOC or similar linear intensity devices:
- volume-foc.funcscript
- intensity.funscript
- amplitude.funscript
- current.funscript

[diglet]

It's a good idea. I have looked into this exact implementation a few months back. But figuring out the precise volume / current curve for my stereostim box was more difficult than expected. So I postponed the research until later.

If anyone is interested in doing the research, basically I need a table that contains the restim volume in percent, with 100% being the maximum volume you use during a session, and the amplitude of the body current. You can also measure the body voltage, but that's not strictly needed. I seem to get different results every time I try to measure this. And if testing takes too long minor changes in skin moisture messes up the data.

He did not propose to have mapping table, just to add another funscript, volume-foc (or one of other names) that will be loaded instead of .volume when foc device is selected. Right now we have to keep 2 sets of scripts as both have .volume.funscript just different

[darthjj]

Yea, I was thinking it would be a good start to have the files clearly tagged before it gets too messy :) But in the long run it would be very nice if Restim could convert depending on what hardware you're using.
