I feel like the verbal guidance on the TMI hemisync tracks is more of a neussance then anything.  I have been also meaning to remove the vocals from these tracks.  I am hoping that the conversions neccessary to do this will not affect the quality and effectiveness of the frequencies.

Seraphis:

Which hemisync products do you use? 

I personally feel that although I most definitely would like to attend a TMI program, it seems to be an overall waiste of money.  Sure, the experience of actually being there, interacting with the other participants, and experiencing the overall energy of the place is unique and gratifying in its own way, but the whole purpose of the programs can easily be achieved in one's own home for free.

Yes, sometimes the voice can be distracting, but sometimes it helps me to concentrate, especially when I'm at the edge of sleep.
About removing the voice parts, when you just cut it out it won't affect the frequencies. What I have noticed though, RAM/TMI apparently have taken some care to time the length of the different stages of their tapes, so I found the structure of most recordings is quite good, and if long voice passages are cut out, it might be good to replace them with copied snippets from before and/or after the cut point. I once made a loop of a nonverbal passage which I liked, and found it wasn't as good as it was in it's original position. Clicks of course have to be avoided, so take care to cut at zero-crossings or make gentle crossfades.

Yes, the vocal guidance does assist in bringing my awareness back if I am drifting off too deeply.  However, it also tends to disrupt my altered states, which is very bothersome.  I'm a music producer, so the actual process of editing should be no problemo.  I was more worried about the conversion in and out of my editing software lowering the quality of the original frequencies.  I suppose I can try to boost them with some equalization.  I'm not exactly sure how subtle the frequencies are or what it would take for them to be damaged.  Ill give it a shot and see how it goes.  Maybe I'll throw some of my own vocals in there for the warm up...  I usually do something different than what Monroe instructs.

I use ear buds and Monroe's voice seems to come in at the perfect time. I like that he's passed on because I feel a closer connection to the ethereal when I listen. But I still dig the non vocalized tracks too. It's just that I don't feel I can stay as focused.
