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 - 852 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 feature is custom tones, you can enter any Hz value and your PC will generate those tones 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.

The ability to play the tones using your computer keyboard also makes it into a fun musical instrument.
