DMG Audio’s Multiplicity is designed to take precision mastering to a whole new level. Potentially quite intimidating but also “shockingly powerful”, it features multiband compression, expansion, gating and dynamic EQ. It can be used to both repair and enhance signals, and all with what’s described as an unprecedented level of control. 

 Features 

1. 8 bands of crossover and dynamic EQ.
2. Dual-stage dynamic handling separates transients and dynamics.
3. Dual-timing release. No more pumping.
4. Beautiful, minimalist user interface.
5. Bit-transparent linear phase crossover and band-splitting.
6. Extensive graphing and feedback.
7. Windows VST, VST3 and AAX as 32+64bit
8. Mac VST, VST3, AU and AAX as 32+64bit
