The paper introduces the software Spectangular for spectral disentangling via
singular value decomposition with global optimisation of the orbital parameters
of the stellar system or radial velocities of the individual observations. We
will describe the procedure and the different options implemented in our
program. Furthermore, we will demonstrate the performance and the applicability
using tests on artificial data. Additionally, we use high-resolution spectra of
Capella to demonstrate the performance of our code on real-world data. The
novelty of this package is the implemented global optimisation algorithm and
the graphical user interface (GUI) for ease of use. We have implemented the
code to tackle SB1 and SB2 systems with the option of also dealing with
telluric (static) lines
