PSP sQuad

PSP sQuad is a bundle of four equalizer plug-ins inspired by the best features and characteristics of classic analog hardware-musicality and simplicity.

The four processors of PSP sQuad are PSP ClassicQ, a Neve-style EQ ; PSP ConsoleQ, an Amek-style EQ ; PSP preQursor and PSP RetroQ. These EQs are CPU efficient enough to be used at every stage of the creative process, from composition to tracking to final production/mixing/mastering.

The Processors in PSP sQuad have a number of features in common with each other, and with other PSP Audioware plug-ins :

- FAT double sampling. In the PSP sQuad bundle, unlike other PSP Audioware plug-ins, FAT is automatically switched on for low (below 50kHz) sample rates, and off for higher sample rates. This ensures the most accurate processing independent of the sample rate.
- 64-bit double precision floating point computations for ultra low accumulative errors in the filters.
- An optional second generation SAT(uration) option in the output of each plug-in. This both protects against digital clipping in software or hardware following the plug-in, and adds a smooth, overdriven sound to hard-driven signals. The SATuration algorithm is located after output level control in a plug-in's internal chain and its ceiling reference level is setup a fraction of dB below 0dBFS.
- All actual parameters like gain, frequency or Q may differ from displayed values which is a typical feature of analog equalizers.
