Saturn2001’s sound journal

[Saturn2001]

I just started working with audacity to build and modify some audio. My need was based on making the best sound files I’ve come across so far, even better. There are a lot of great stereo files out there, but so many of them have these nulls in unexpected spots. There is nothing worse than being ready and wanting to finally orgasm, and when that moment comes, there is a long quiet spot in the file, lol. I needed an orgasm file that I could just quickly swipe to that pulses well and lends to the orgasm. I literally stimmed today with a paper and pencil, and wrote down time blocks of sections of my favorite audio files with descriptions and intensities of the sensations, so I could dissect them on audacity later on.

There are days where I can easily stim to orgasm 3-4 times a day with no problem. I’ve found this is due to properly utilizing power, electrodes, and playing the right files to not overnumb the body parts.

I’m also trying to develop a way to design sequences that will work well with movies. This opens up many new aspects that need to be taken into consideration, stuff far beyond the original scope of the manufacturer. I have made a few observations in my work today...

For faster pulsing, the response is not horrible, but what needs to be done is any lower tempo signals need to be driven at a lower amplification/amplitude in the audio track, so the higher tempo signals can be turned up (amplify feature in audacity) on the audio track; this way there will be a balance of intensity. Otherwise short pulses will feel much weaker than longer or sustained pulses. This is why so many files give people the “unexpected” surprises they feel at certain points. Some people like that; I particulary do not.

Also, on the 2B, there is a slight input lag after a short period of no input. This can be rectified by adding in a 1/2 second burst of sound just before the intended sound is played. The short burst will not be felt; it just serves to “wake up” the amplifier in time for the intended sequence.

I am normally very busy with my career, but I currently happen to be stuck away from civilization for several days, and have absolutely nothing else to do, so I started working on a soundtrack to a very well produced virtual reality movie. I can say for a fact that with the audio done properly, it is EXTREMELY convincing, literally mind blowing when just the right sounds are synched properly to the video. Its far better than I thought it would be. I never initally even had any interest in pornographic material while simming, but the new VR POV stuff is just amazing. I’m still trying to figure out how certain sound envelopes and channel balance lend themselves to deeper or more tingly electrode sensations based on what is seen in the movie, which is what makes truly makes an estim soundtrack so much so convincing.

I could be wrong, but it seems the 2B does not reproduce frequencies, just amplitude? Higher and lower frequencies seem to feel very similar. It seems to me the duration of the signal is what ultimately leads to the depth of the sensation.

The 2B definitely does reproduce frequencies but they are digitally interpreted with the highs and lows 'trimmed'.
See my explanation here: https://www.e-stim.net/viewtopic.php?f= ... 762#p14762

Personally I don't have a problem with this because I don't particularly enjoy the missing frequencies or their resultant spikes.

[Saturn2001]

So its generally done with a different pulse width modulation, as I understand. Can you tell me what frequency ranges the 2B uses, and any frequencies you’ve found in particular seem to process the best or most efficiently by the 2B?

[Stimaddict]

The 2B's frequency range is generally between 50Hz and 5-6Khz, although it tails off towards the higher frequencies. In reality very high frequencies cannot be felt even using a StereoStim device, but they can still potentially cause damage which is why the 2B ignores them.

It's not as simple as 'liking' this or that frequency but I'm probably happiest in the low to mid-ranges. Continuous stimulation doesn't really do it for me. I prefer a moving range of frequencies in a stimfile to produce a mixture of waveforms and their consequent sensations.

Thanks for the info. Same here on the continuous. Your Bastard file is my benchmark and go-to. Nothing else I’ve found even comes close to it.

I think you've definitely found what I've noticed, except I think of describing it as follows:

- lower frequency sounds, and I believe to an extent, lower frequency-modulated sounds, will tend to "feel louder/stronger" and thus need a lower amplitude.
- conversely, higher freq sounds occur more quickly and thus need higher amplitudes for a similar feel.

I've discovered this playing with the web page, Electron. I've actually downloaded all of the code and have been building a version of it to allow for loops, saving/loading sequences of sounds, etc. Still very beta. But, it allows for quick experimentation with understanding the freq/amp relationship I described.

For example, if I have a sound segment at 200hz (freq) at a volume level of 30 (amplitude), but then segue to a segment at 2000hz (at the same volume level), the higher freq doesn't feel as strong. So I can adjust that sound segment to have a vol/amplitude of 50, and it feels equivalent to the 200hz/30amp sound.

So sure enough, a lot of sound tracks may produce everything at the same volume/amplitude level, while varying the frequencies of segments throughout. Those unexpected jolts tend to arise when the volume output is set high (say at 60, again, an arbitrary value) to accentuate a high freq sound, then the place a low freq sound envelope right after it at the same volume/amplitude level...and Wow! You really feel that sound. Also as you say, some really like that flash of pain/change, others do not.

I'm similar to you, where I prefer to have a more consistent "feel" throughout changes of the waveform (freqs), and thus strive to create audio tracks with varied amplitudes across the changing freqs. It is definitely more work to sync and figure things out. That is where the Electron web site helps (https://electron-btstim.herokuapp.com/), as you can quickly try out various waveform to see what works well at what volume level. I hope someday I flesh out my version a bit more and I'll share here with everyone. I don't run it on a widely accessible server - I just run XAMP or WAMP on a local machine and access it that way.

Anyway, good thoughts and discussion. I hope you share with us your new audio track so we can try it out.
