I have done binaural and isochronic tones for health cure and meditation It can be from Sleep apnea to anything. Name a disease and we have it. I can embed them with background voice without being heard -hypnotics do use my creations. This can be useful to any health company/doctors/meditation/yoga therapists just to include a tone inside their music,demo,song,lecture to get the desired result. Example: My sleep track tested by community people and found to be working to the desired result. I have a team that works tirelessly to achieve your desired results.
