Great! Glad you've got the files available. I started working on this with the raw audio from the vid but the beats will make it way faster and more accurate. The file that is most helpful is JUST the stroking beats; the music confounds the beats that I mimic with stereostim beats.
When I'm not swamped with real life, I'll put together a step-by-step how-to guide on creating these; the more the merrier and I'm always up for trying out others' creations.
Here's a few tips to get you started.
1: Your first creations won't be that good. There's a learning curve both with how to create pleasing sensations and with using Audacity (assuming that you are using Audacity. If you're not, almost everything I can put together will be pointless to teach you).
2: I have found that the best way to make these is to start with a base file that acts as a library. I have a few at different wavelengths. My recent posts have been at 800Hz but I'm experimenting with 2MHz (2000Hz). To me, it provides a more smooth, less spikey sensation. I'll be looking for feedback when I make my next one to see what people prefer.
Anyhow, I created beats from 0.100 - 2.000 seconds in 0.01 second increments at the given wavelength. In Audacity, this can be done by the following steps:
1 - Start with a new file and add select "Track", "Add", "Stereo Track". You'll have a blank stereo track.
2 - Select "Generate" , "Tone", and I use Sine Waveform Frequency as discussed above amplitude 0.7 and length somewhere around 10 minutes is more than enough to create the library.
3 - Set "Selection start" (bottom of screen) to 0. Set the next box to "Length" and select 00h00m00.100s and press ctl-i to add a separator. to segregate the first 0.1 second from the rest of the track.
4 - With that section selected, select "Effect" and go to "Nyquist Prompt".
4a - Make sure "Use Legacy (version 3) syntax is checked otherwise this won't work!
4b - Copy the text below into the command box:
(mult s 0.5
(sum 1.5
(osc (hz-to-step (/ (get-duration 1)))
1 *table* -90)))
4c - Click "OK" (Pressing Enter continues to enter blank lines in the command box - doesn't hurt, but doesn't complete the action)
If this is done right, you should end up with a 0.100 second wave that comes up and down. With these settings, you'll always have some sound between beats. This is a personal preference, but I like to have constant stimulation, even during rest periods so I make sure every beat goes to a trough with some volume rather than going silent. Experiment with the first 2 numbers (0.5 and 1.5) to see what they do to the wave form. The duration number (1) in the section above denotes how many waves you get in the period selected. This number is inverse - if you want 2 beats in the selection, make the duration number 0.5. If you want 4, select 0.25, etc.
Repeat steps 3-4c for lengths of time increasing by 0.01 seconds until you have everything from 0.1 to a second or more. I use a macro to make this a lot easier but I'll leave that ingenuity to you based on your software and settings.
I also repeat each wave a second time and then go to the mid point and hit ctl i again to slice it in half. This way I can select half of one length and half of another to make for smooth transitions. For instance, if the CH is going from a 1-2-3-4 to a 1-2-345 beat, the transition from the 2-345 will be a long first half, a short second half to keep up with the 3 beat, then a short whole beat for the 4, then a short first half and long second half for the 5 beat leading into the longer 1 beat.
This is all really hard to describe by text but if you look at the files I've posted lately in Audacity, you can see that anytime there's a change in beat tempo, the beat starts at one speed, hits the peak, and then ends faster or slower. This is done with these half-beats.
Anyhow, once I've got all of the beats for a CH replicated, I fill in the blank spaces with roughly 0.5 second repeating beats just to keep the sensations going. At this point, everything is a constant volume.
I change up everything that doesn't correlate to a beat to about 50% amplitude right off the bat with a ramp up of 2-3 beats depending on my mood. So leading into a new round, the lead up would be at 50% (Use effects - Adjustable Fade). Then the 2 beats before go from 50-100% using the same function. Once all of the silence has been accounted for, I'll adjust each round progressively higher. Typically I start round 1 at 70% and end round 1 at about 75%. Round 2 goes from 72%-78% etc. until the final round which starts at 100% and goes as high as 120-130%, again, depending on my mood.
Everything has to be a smooth transition though; you don't want to start a beat without some sort of lead-in. Trust me, if you don't, it hurts.
Anyhow, I guess I just found the time to type out a primer on how to create these. I'm sure I've left some out and if you have questions, you can post them here, on the stereostim thread, or PM me. One way or the other, if you can post just the beats to Blue Angel, I can't wait to get it done to add to the list!
Enjoy!
