The extended Wiener model contains technology that keeps constant energy of the output signal for all distortion levels. The nonlinear model extends the standard Wiener model and introduces dynamic nonlinearity and frequency-dependent nonlinearities while keeps the computing demands low. The non-linear part of the model uses proprietary model based on the Wiener model. The parallel structure of 2nd-order minimum-phase filters brings extremely low latency, minimal phase distortion, and high stability. The dual-band design brings even more precise modeling at low frequencies without reducing precision at high frequencies. Thanks to the filter design on a warped frequency scale, the frequency resolution of the model takes into account the frequency resolution of the auditory system. More info here: Balázs Bank and Germán Ramos, "Improved Pole Positioning for Parallel Filters Based on Spectral Smoothing and Multiband Warping," IEEE Signal Processing Letters, vol. The linear part of the model uses transfer function modeling by fixed-pole parallel filters based on the dual-band warped filter design. Read more about the science behind the algorithms. We not only added the modeling of non-linear behavior, we have also completely rewritten the original processing to achieve phase linearity, lower latency and better resolution in all parts of the frequency spectrum. The original MixChecker contains only the simulation of the linear behavior of the devices. #AUDIFIED MIXCHECKER R2R FULL#See the full explanation in the user manual. In some cases they helped the simulation process but for many speakers it had negative impact to the fidelity of simulation.
