Violet aka purple noise power density increases 6 db per octave with increasing frequency over the frequency range. It is also known as differentiated white noise, due to its being the result of the differentiation of a white noise signal. I created this by looping http://en. Wikipedia. Org/wiki/file:purple_noise. Ogg. Which is copylefted, however i claim that they can't be protected based on http://en. Wikipedia.

Typing (real words!) on a kinesis advantage keyboard with cherry mx brown mechanical switches. Recorded at my desk with rode procaster, triton fethead, focusrite scarlett 2i2 into audacity. Untreated room (hence dynamic mic) but noise remoived with audacity. I needed this for my own purposes so i thought i'd upload it. I hope someone finds it useful :).
