PLParEQX utilizes our X-Technology to provide phase-linear filtering at a very light CPU loading for Intel and AMD computers.

Whereas PLParEQ is an ultra-high quality phase-linear parametric equalizer for mastering use, the X-Technology series offers slightly lower quality at significantly reduced CPU loading, making them useful for routine mixing and tracking applications.

PLParEQX is a 10-band version, it offer high-quality oversampling in the processing and up to 5 levels of Quality. The lower quality levels are useful when you need minimum processing latency, and in turn you are willing to accept increased levels of sonic artifacts. Our measurements indicate that the lowest quality level has IMD products about 96 dB below signal levels.

Our X-Series filters are 64-bit ready for Sonar 5, and offer classical filtering shapes in purely phase-linear mode for minimum sound degradation, especially in sharp attacks when imposing strongly varying filtering with frequency.

We offer a full complement of lowpass, bandpass, band-reject, and highpass filters, classical shelving and peaking filters, as well as some novel low-slope filtering for when you just need a slight attenuation with frequency. Also offered are A, B, and C weighting filters, and a killer 6-pole Notch filter for absolutely killing that bothersome spur.

The magic of our X-Technology is such that no matter how many filters you activate, the CPU loading is the same low level. On tests with a 3 GHz Pentium 4 we find the loading in Sonar 5, running in 64-bit mode, to be around 4% -- significant
