Cobalt Saphira from Waves is an advanced harmonics shaping plug-in tool for mixing and mastering that allows for adding rich harmonics to tracks in order to impart an analog musicality, depth, and "glue," without resorting to compression. Excelling on groups & sub-mixes and in mastering situations, the software provides rich harmonic enhancement that can be creatively tailored to taste.

Four control sections include Edge and Warmth for separately controlling and balancing even and odd harmonics, and a 4-band EQ for shaping the frequency spectrum of each type of harmonics. Seven different harmonics modes with graphical representation provide visual feedback of changes made in the harmonic structure, while tape modeling with five tape speeds allows for adding wow and flutter modulation for extra "musicality and depth."
