| contents | We introduce a novel logarithmic spectral estimation method for dark matter searches using gravitational-wave detectors, integrating established dark matter search techniques with insights from computer music analysis. By leveraging symmetries between the time and frequency domains, this method matches the computational efficiency of FFT based algorithms without, unlike such algorithms, compromising precision. We apply this approach to data from LIGO's third observing run, directly comparing its performance with that of a previous search. Our results show a consistent 15 percent improvement across nearly the entire frequency range, without additional computational costs. With potential for further refinements, this method already offers a solution capable of maximizing the scientific potential of current and future gravitational-wave observatories. |
