I see this was recent...and the answer was correct. However, if you get the chance, get some of TMI's spacial angle modulation (SAM) downloads. SAM is more powerful than hemisync and can present higher entrainment frequencies than hemisync can; the brain only responds up to about 20Hz hemisync, but SAM can get you into gamma, 40Hz and up. Some of the most wonderful experiences I've had are in the gamma frequency realm. I don't think they are still calling it SAM but it is still spacial angle modulation pretty much.
