Sirax Mastering Suite by Aurora DSP is an all-in-one mastering plug-in that combines dynamics processing, precision EQ, stereo enhancement and advanced metering in a streamlined workflow.

Nine modules take your mix to a polished, release-ready master: Glue for bus compression, Smooth for taming harshness and resonances across four bands, Dynamics with broadband and multiband compression, a 10-band EQ, Stereo for width and spatial balance, Color for saturation and harmonics, Clipper, Limiter with true peak protection and PumpUp for extra density and presence after limiting. The first seven stages can be reordered at will, while Limiter and PumpUp stay at the end of the chain. The integrated Master Assistant analyses a section of your audio and proposes settings that you can review, modify and apply. Sirax suits individual tracks as well as full albums, for electronic and acoustic productions alike.
