The simplest gravitational waves are those with constant frequency. The waves given off by a spinning, non-axisymmetric neutron star would be approximately [[monochrome|monochromatic]]: a [[pure tone]] in [[acoustics]]. Unlike signals from supernovae or binary black holes, these signals evolve little in amplitude or frequency over the period it would be observed by ground-based detectors. However, there would be some change in the measured signal, because of [[Doppler shift]]ing caused by the motion of the Earth. Despite the signals being simple, detection is extremely computationally expensive, because of the long stretches of data that must be analysed.

The [[Einstein@Home]] project is a [[distributed computing]] project similar to [[SETI@home]] intended to detect this type of gravitational wave. By taking data from LIGO and GEO, and sending it out in little pieces to thousands of volunteers for parallel analysis on their home computers, Einstein@Home can sift through the data far more quickly than would be possible otherwise.<ref>{{cite web|url=http://einstein.phys.uwm.edu/|title=Einstein@Home}}</ref>
