What is White Noise?

White noise is made up of many different frequencies of sound combined together at equal intensity. Its name is analagous to white light which is a combination of all of the different colors of light in the visible spectrum.

What is Pink Noise?

Pink noise is a variation of white noise that places emphasis on bass, or the lower frequencies of sound. Its called pink noise, because if you were to do the same with the visible light spectrum you would get a pinkish color.

What is Brown Noise?

Brown noise is a variation of white noise that places stronger emphasis on the lower frequencies of sound than Pink noise. In the light analogy this would yield a deep red color. But since the noise coincides with a mathematical model called Brownian motion it is instead called Brown noise after the physicist Robert Brown.

흠...

백그라운드 기능 이용하려고 유료로 구매했었습니다. 덕택에 광고도 따로 나오지 않았었고요. 그런데 이번에 업데이트 받았더니, 광고도 다시 나오고 백그라운드 기능도 안되네요. 다시 유료 구매하라는 배너만 나옵니다. 이번에 프로그램 변경하면서 이전 구매자들 개선이 안되서 다음 업데이트까지 기다리라고 하는 것 같은데.. 혹시 누락될지도 모르겠어서 글 남깁니다. 아주 불편하네요. 확인 해 주시고 빨리 개선해 주셨으면 감사하겠습니다. 참고로 아이폰 4 이용자입니다.
