Acustica’s Coral is a mastering channel strip with transparent EQ and detailed dynamic control.
A wide-band equaliser and 'Chimera' mastering compressor can be linked or switched from stereo to middle side operation, then combined in a central section that includes an elliptical filter, a preamp simulator and three routing configurations to improve workflow flexibility.
The mastering wide-band EQ has an unique and innovative design including four EQ bands and two filters section with gentle slopes and sub-Bessel configuration.
Coral's 'Chimera' mastering compressor is also unique and innovative, thanks to the high number of rectifiers in the detector section, but also due to its application of a soft-clipping strategy. The compression applied to large dynamic areas is gentle and gradual, preserving transients without hard cutting.
Conventional dynamic compressors usually use a hard-clipping strategy, which flattens short transients and peaks abruptly (kind of a limiting strategy): when applied to a large audio portion, the result may be a bright yet harsh sound.
The EQ’s strategy is also based on being applied gently and gradually on large portions of the audio band (so a large and smooth bell), impacting the overall spectrum balance in the most transparent way.
We have also added an elliptical filter, which is often used in the vinyl mastering domain and is also appreciated in other fields for the low-frequency stereo control.
As with Acustica’s SAND release, they have created a BUNDLE including each individual module, enabling the use of each component separately, with a significant saving in term of CPU.
Known as CORAL REEF, it includes:
