Second View: Seeing Double in FIR Designer
Second View is an additional window that can be used during the DSP design process to monitor, in real time, how your adjustments affect EQ variables beyond those displayed on the active workflow tab.
The Second View window can be configured to show one of the following:
Open a Second View window from the checkbox above the workflow tabs. Once opened, it can be configured to display the desired plot.
The window can be positioned anywhere on the primary display, or moved to a separate monitor for use in a multi-screen setup.

Workflow EQ Plots
The Second View window can be customized to display any plot available within the workflow, including those from the Gain/Polarity/Delay, IIR Filters, Mag Adjustment, Phase Adjustment, Auto Mag, Auto Phase, Voicing, and Export tabs.
These plots directly mirror the corresponding plots on their respective workflow tabs. This allows you to view multiple aspects of the design simultaneously, making it much easier to compare the impact of EQ adjustments in real time, without needing to switch back and forth between tabs during the design process.
All edits are made in the active workflow window. As you adjust parameters or modify plots in the active window, the changes are immediately reflected in the Second View window. The Second View itself is display-only, meaning it does not accept direct edits—its purpose is to provide a continuous, real-time reference of other plots while you work.
Reference Response
The Second View Reference tab allows a separate response measurement to be loaded and used as a reference during EQ design. This is typically a measurement file that has not already been imported via the Import tab, and serves as an additional comparison or target within the workflow.
When enabled, the reference response is displayed as a background plot in all the response plots in the Second View window. It appears behind other active plots, and its visibility can be independently toggled on or off for each plot as required.
The magnitude of the Reference Response can also be optionally inverted, which is helpful when trying to mitigate a response rather than match it.

Continuous Wavelet Transform
Available as an option within the Second View Export tab, view a time/frequency map of the loudspeaker impulse response, with or without filtering. The view includes adjustable wavelet width & view scaling.

Group Delay Display
Available as an option within the Second View Export tab, use the Group Delay Display to view the time delay, through the combined processing, as a function of frequency. The group delay of each of the IIR and FIR filtering can be viewed independently.
