This standalone application (no installation needed) allows you to generate the purest of frequencies using your PC. Volume sliders are available for the six sacred Solfeggio frequencies: UT - 396 Hz - Liberating Guilt and Fear RE - 417 Hz - Undoing Situations and Facilitating Change MI - 528 Hz - Transformation and Miracles (DNA Repair) FA - 639 Hz - Connecting/Relationships SOL - 741 Hz - Awakening Intuition LA - 825 Hz - Returning to Spiritual Order Double precision sinusoids are generated in real time so frequency purity will be as high as your hardware is capable of. The use of high quality headphones or speakers is recommended. A Fibonacci arpeggiator is included, tick the tones that you wish to be included in the sequence and turn up the Fibonacci Arp Level. Optional white noise is available for added ambience. One neat extra feature is a custom tone, you can enter any Hz value and your PC will generate that tone exactly, very handy if you want to tune an instrument to a custom tuning like 432Hz. This freeware tool is great for experimenting with Cymatics or any other sonic experimentation.
