and is there a cheater chart anywhere that i can find what isochronic tones are what hz and/or what hz translate to 16th, 32nd, etc notes in what bpm?

I mean yes obviously two sine waves but doesn't each one have to be a specific frequency to properly stimulate the alpha/beta/delta waves, etc? I just know that the ones i have listening to are two distinctly different tones oscillating at different rates.
Well i did over simplify a tad. The tones are typically sine waves one is just set lower than the other and they are played in separate ears. The HZ rating of the binaural beat is the same as the difference for both tones. Still its not a huge mathematical ordeal C3 would be 130.812Hz Db3 is 138.591Hz if the two tones are played isolated in separate ears than the percieved beat is about 7.779 because 138.591-130.812=7.779. Does that sorta make sense kinda? Isochronics are a tad less confusing than binaurals but neither of them are insanely complex. Also a lot of brainwave stuff uses ramping, where they start in on place and end in another, for example a sleep oriented set of beats or tones may go from 13HZ to 9HZ to 6Hz to 2Hz. I really hope I'm not being too confusing

All these numbers are so confusing to me man, you got a link for where you learned about this? I'm super confused.

I'm not sure man its all knowledge I compiled from a bunch of places and other people who where working with it, I think wikipedia has a pretty accurate article on binaural beats though their isochronic article is lacking, but here is my cheater chart for isochronics.
32nd note LFO at a tempo of 140 is 18.6666/beta waves/somewhere around normal consciousness
16th note LFO at a tempo of 140 is 9.3333Hz/alpha waves/dreams/relaxation.
8th note LFO at a tempo of 140 is 4.6666Hz/theta waves/sleep.
1/4 note LFo at a tempo of 140 is 2.3333Hz/delta waves/deep dreamless sleep
32nd note Hz is the tempo divided by 7.5
16th note Hz is the tempo divided by 15
8th note Hz is the tempo divided by 30
1/4 note Hz is the tempo divided by 60
Also this is really helpful with binaural
http://en.wikiaudio.org/images/b/b4/MID ... _chart.png That is just a chart I think everyone should have a copy of though.
Also if anyone here is using reason I can e-mail you my rough combinator patches.

Note that for this to have a legitimate effect, the oscillation would have to be constant throughout the whole song and also the listener would have to be in a relaxed meditative state to be receptive to brainwave entrainment. Doubt it would work in a busy upbeat song with a bunch of stuff going on. If you made it a really prominent part of the track and had it go long enough I could see it having an effect but... who's gonna listen to a 9 minute track with 32nd note square wave wobbles?

I'm actually going for 16th notes/alpha waves

haha but you're right I think I said something about that earlier maybe. The most challenging part is to keep the song interesting and long. Right now I have the isochronic tone in a higher octave. Then the sub bass is also an isochronic tone and its all very heavily equalized. That way the mids are free to carry a melody and keep the song going. It's hard to keep interest but I think its possible. I'm definitely going for a chilled out trippy-ish song nothing super upbeat.

I know this is necro posting but I'd kinda just like to comment on my results. I found that it was possible to produce a track which featured working isochronic and was still interesting, however the listener cannot focus on the music draws the listeners attention away from the tones. Ether the tones are completely blocked out by the brain because of the music or the tones have to totally dominated the entire track to the point where you can hardly hear anything else.

I remember reading that they're completely subliminal and having some other sound to listen to actually helps? Like some products have music laid over top of the isochronics to keep your attention. All the ones I've heard have said not to pay attention to the tones but to focus on something else. Music would have to be minimally stimulating though. Already inducing trance state without the isochronics.
Try setting up an amplitude mod buss and route some tracks there for extra effect. Moar powar!

Haha I'll give it one last try I do want this to work. Maybe the tones shouldn't be exactly on the beat it may work better if they didn't match up with the song so I'll try that
