Starting Up
The image below shows the home page of the FIR Wizard.
From the home page, the user can choose to:
1) Start from an existing Wizard project: click the open button at top right of the screen and a file
browse window appears allowing to select a Wizard project file (.zwz)
2) Start from an existing IR, that has been already measured and saved from the FIR Wizard: click the
“Open existing IR” button at the botton center of the screen and open an IR file (.oir) from the file
browse window.
3) Start with a new IR measurement: to do this, be sure you have an ASIO sound card, a measurement
microphone and, at least, a 4m x 5m x 4m (L x W x H) obstacle free measuring room (if the available
space is a little bit smaller check for possible tricks described in the following section). Moreover, as
already described in the “Preliminary” section, it is suggested to set up the Xover, the PEQ and the
output delays to have a nearly flat frequency response on axis. Then, click the two reminder
checkboxes to enable the “Measure IR” button and click it to proceed with IR measurement steps. At
this time, all the dinamic processes in the DSP will be automatically turned off, as well as the
equalization FIR filter that could be already active.
