Sonoris Multiband Compressor

The Sonoris Multiband Compressor was developed to be a versatile multiband compressor suitable for mastering or mixing. It is meant to be a compressor that can be very transparent but also have some “character”.

It has three independent frequency bands followed by three compressors based on the Sonoris Compressor. The three bands are created with special designed filters to avoid phase cancellation problems. These filters are known as Linkwitz-Riley crossover filters and have a very natural, analog like quality. By design they mix back flat. Unlike linear phase filters they don’t introduce delay and are more efficient in use.

Transparency can be achieved by selecting auto-release and opto envelope emulation together with two soft knees. If a more warm sound is needed you can for example choose RC envelope emulation with a harder knee.

The SMBC has three high resolution gain reduction meters and a transfer graph, so you can actually see what you are doing. The ratio is allowed to be lower than 1 so it’s also an expander. Maximum ratio is infinity for limiting action.

The individual bands can also set to limiting, what results in a multiband limiter!

The output section of the SMBC also features a limiter. This guarantees that the output will never exceed the 0dB point. This limiter can also be used as an effect to “warm” up a signal.

The SMBC is able to process one channel only. With this feature, in combination with the Sonoris MS Codec, it is possible to perform very powerful processing in the MS domain.
