I would like to generate low clean low frequency sine wave with Linux hardware. Does anybody know good setup for that? What thingies I need for the hw to be able to output the wave? What software other than custom can be used to control the amplitude and frequency?

what about hardware you use ? And you must have software that can connect to a particular designed hardware

Cosmophone (# glucophone) is a vibration of sound, solemn lull, unity that filling space. A special proportion of hemispheres, petals (notes) and resonator excess an extremely productive of palette of overtones.
To place an stunning factor - a petal tone drum, popularly known as a “glucophone”, a perception of rhythm is enough. His sound is sincerely mystical. And you can learn to take part in it, literatim, in a some minutes - the most important emotional attachment is to just learn how to worst on metal tongues, and it always sounds magical.
