PSP MasterQ2 from PSP Audioware was designed it to be a creative tool for mixing and mastering, wherever its features and quality are needed for the job.

The MasterQ can operate at sampling rates ranging from 44.1 to 192kHz and offers seven filters—12, 24 and 36dB/oct low-cut and high-cut filters, low shelf and high shelf filters which can be switched to peaking filters and low-mid, middle and high-mid peaking filters. Each of these includes adjustable frequency and Q over a wide range. The EQ graph displays an overview of the EQ curve, as well as the individual characteristics of each filter. In addition to its powerful filters, PSP MasterQ2 also offers you a selection of limiting and “soft-clipping” algorithms to help you shape your signal and keep it from digitally peaking.

PSP MasterQ2 also employs 80-bit extended floating point computations in all filters to deal with accumulation errors, allowing for optimal filter operation—at even the lowest frequencies with high gain and Q factor settings. PSP MasterQ2 uses the proprietary Frequency Authentication Technique (FAT) algorithm. FAT is a double sampling technique which allows for proper filter operation at the highest frequencies and utilizes high order linear filters to prevent errors from the audio bandwidth caused by double order sampling. This technique results in double sampling without sample rate conversion artifacts.
