I haven't tried it yet. I also have the Mind Work Station which is software that runs on my PC. I think I can import the LifeFlow MP3 to it and add audiostrobe if it's not already there.
To output the audiostrobe I plug my Proteus into the headphone jack on my computer and get the sound and strobelight that way. I do this because the audiostrobe feature only creates a flashing screen on the computer if I don't go through Proteus.
My Mind Work Station enables me to create my own entrainment sessions using all of the entrainment methods and frequencies.
I know you can program Proteus too but the Mind Work Station is so much easier and much more powerful in terms of what you can do with it.
Lately I've been experimenting with gamma frequencies, but can't report anything spectacular yet.
