Inappropriate Ads

Warning. The ads had pornographic images. Please use other ads. People want to sing, not to be scandalized.

Humming @ 130-150 Hz

I learned about nitric oxide release from nasal humming (called many different things in yoga and other disciplines), but you have to hum within a certain frequency range to do this correctly, this app is *brilliant*, the only thing I have ever seen that does this, and it does it super well and super easily — and does many other things. HUGE thanks and respect for this.
