Latency values below 20 milliseconds ensure that any pre-ringing is masked by the temporal masking of the human hearing while preserving the time-alignment across the audible frequency range. That gives a unique control over potential pre-ringing artifacts which is a common problem with linear phase filtering.
Equalize goes one step further, though, and introduces the unique mixed phase mode that allows you to set the latency freely in the range 5 to 120 milliseconds while preserving the phase relationships as far as possible. Needless to say, you can operate Equalize as a zero latency plug-in when using the minimum phase mode or choose to preserve the phase relationships in the linear phase mode. The filter slope can be set anywhere from 3 dB to ultra-sharp 120 dB per octave.
Unlike other equalizers, you can freely adjust not only center frequency, gain and bandwidths, but also the filter slope for each band. The parametric analysis provides a more comprehensive view of the assumptions and limitations of the design methodology and suggests additional recommendations to improve the design requirements of the SC-CB connections.Acon Digital Equalize is a parametric equalizer plug-in that combines unique features with excellent workflow and an intuitive user interface. Successively, FE models of three SC-CBs belonging to different case-study MRFs are developed considering sixteen Configurations for each case characterised by different design parameters and structural properties. An advanced FE model is developed in ABAQUS and validated against experimental results. In this context, the present study focuses on the steel damage-free Self-Centring Column Base (SC-CB) previously investigated by the authors and performs a parametric Finite Element (FE) analysis to evaluate the influence of some design parameters over the global and local response of the joints. However, although several technologies have been conceived, studied, and experimentally tested in this direction, only a few research studies investigated the significant properties of the connections influencing the behaviour of these systems. In this regard, self-centring Column Bases (CBs) represent a promising solution to improve the seismic performance of steel Moment Resisting Frames (MRFs) for both damage and residual drifts reductions.
In recent years there have been significant advancements in the definitions of innovative seismic-resilient structural systems, chasing the urgent need to reduce repair costs and downtime in the aftermath of severe earthquake events.
