Read full descriptionHide full description
A fun and free tone generation app. Choose Prime numbers, Healing frequencies; Earth Pulse derivatives, Schumann resonance (audible), and make your own Custom tones. Load and Save from Files (including Cloud). Choose the number of channels to generate tones with, from Mono (1 channel) all the way up to Atmos 9.1.6 (16 channels), with cool waveform graphs (pinch-able) to show each category of tone being generated, and a summary waveform graph for the entire mess that you have created! Three selectable Phase Adjustments can also be applied (None, Tri-Phase, and Five-Phase). And don't worry that you can't get a 16-channel amplifier and speaker setup connected to your Apple Device - you can click on the "Mix Spatial" button and get Spatial Audio output generated (best listened through Air Pods).
