They are similar in concept, but the way they deliver the energy to you feels different to me. HT4U’s AudioTalisman converter feels more like a spiritual download via the crown chakra (similar to radionics) while Maitreya’s Field Creator is processed by your body/aura.
It’s my opinion that Maitreya’s Field Storage Creator will be more effective for physical changes and I’m testing that now. I never got physical changes with the AudioTalisman Converter even though I’ve been using that tool for about 6 months now.
