The Sonoris Multiband Compressor (=SMBC) is a versatile three band compressor in VST, VST3, AU, AAX and RTAS format for Windows and Mac. It is an ultra clean processor, suitable for delicate material. It has three independent frequency bands, each followed by a compressor based on the Sonoris Mastering Compressor. The three bands are created with carefully designed Linkwitz-Riley crossover filters to avoid phase cancellation problems while having a very natural, analog like quality. By design they mix back flat. Unlike linear phase filters they don’t introduce ringing artifacts and are more efficient in use.
