The sine wave is a sound wave that has a single frequency with no harmonies. Because of these qualities, it sounds perfectly clear to the human ear. JAZ Records are releasing 'Sine Studies 3' by Loscil. . According to the press release, Locsil shapes sine waves, 'imbuing them with texture and colour through the use of layering, processing and distorting.' If you were being cynical, then you would say, well, that's all electronic music is really, but since we aren't cynical at NR, we won't. It's an accessible and enjoyable investigation and exploration of the possibilities of digital sine waves.
