• Custom – user draws custom curve to be applied in addition to ASIF
flattening
Note: Changing the output shape does not require an adaptation period
to arrive at a “good” solution. Because a full average spectrum is
maintained regardless of the output shape setting, the new output shape
takes effect instantaneously in both the output audio and the display
traces. However, since the auto gain adapts based on the actual applied
filter with the shaping curve taken into account, there may be some
adaptation time required to reach a stable auto gain value after the
shaping curve is changed.
Custom Curve:
To draw a custom curve, select Custom and then click the Edit button
beneath the Custom selection button; the ASIF Custom Curve window
will open. Click New to begin a new curve. To draw the curve, use your
mouse to make single clicks within the axes; the curve is built piecewise
by “connecting the dots” at the click locations. For fine control of the
click locations, use the cursor coordinate information located at the
bottom of the drawing axes. The ASIF custom curve drawing window is
identical to the Hi-Res Graphic Filter drawing window. For more
information on drawing a custom curve, see Section 4.4.13: .
You can save custom curves for later use. Click the Store button to save
your custom curve to a file. Click the Recall button to load a custom
curve that was previously saved to a file.

Filter Output: The controls in this block allow the user to make adjustments to the filter
output. An output level bargraph is shown as an aid to determining the
