A lot of Sonic Access has only a single voice -- in other words, it's not a double voice paraliminal throughout.
After the initial single voice intro, there's a double voice part. Then it goes into a long single voice part (over half of the meditation) with specific meditation imagery about the scene you're in, where you're walking, what you see and do.
For the sake of being complete, I'll also note that at the end, there's an invigorating song sung by a group. Chunyi Lin chants the heart sutra during the song or at other points.
If I don't get into a meditative state during the double voice part, I find it fairly irritating to listen to the single voice part consciously. The imagery is annoying to me - though it would be fine as half of a paraliminal.
I really like Sonic Access, but I wish it were all double voice. Sonic Access can be inspirational, even sublime, and I'm glad I have it. But the single voice part is a significant negative for me.
