Figure 4-40 SIF Custom Curve Window

Build Button: Builds the spectral inverse filter based on the original input audio

spectrum and the SIF control settings. When clicked, the mouse cursor

will change to an "hourglass" shape, indicating that the PC is busy

calculating the spectral inverse filter coefficients and sending them to

the external processor. When the filter build is complete, the mouse

cursor will return to normal and the calculated spectral inverse filter

curve will be displayed as a blue trace in the Filter Display area.

Hint: Before clicking the Build button, it is recommended that the

spectrum analyzer be set to Freeze to allow experimentation with the

control settings for the same input spectrum.

Filter Active Button: Used to switch the filter in and out of the process without affecting the

operation of the other filters. Button LED is illuminated RED when the

filter is in the process, and is not illuminated (GRAY) when the filter is

out of the process.

NOTE: The Active button is also available in the associated Filter block

on the Master Control Panel.

OK Button: Use either this button or the “X” button at the upper right corner of the

window to exit the dialog and return to the Master Control panel.

Store Button: This button allows the user to store a calculated spectral inverse filter

curve to a file, which will not be lost when the computer is turned off.

Clicking this button brings up the Store Spectral Inverse Filter

window (Figure 4-41) referencing the current working folder. Once a

valid file name is entered in the File Name field the OK button in this

window will be enabled. Clicking the OK button will recall the
