Auto Fit
The Auto Fit function is designed to generate a
noise curve for audio that lacks a noise-only
portion for DINR to learn. Clicking Auto Fit
computes this generic noise curve based on the
points contained within the currently selected
audio, then fits the Contour Line to it. To use the
Auto Fit function, you must first make a selec-
tion in the Spectral Graph by Control-dragging
(Windows) or Command-dragging (Mac).
If the selected audio has both noise and desired
sound components, you can generate an approx-
imate noise-only Contour Line by selecting a
frequency range that appears to be mostly noise,
then pressing the auto fit button. You can then
edit the resulting noise Contour Line to opti-
mize the noise reduction.
Move Breakpoints Up/Down/Left/Right
These arrows behave differently depending on
whether or not there is a selection of points
along the Contour Line.

Controls
Scroll Left/Right
These buttons scroll the Spectral Graph to the
left or right, respectively.
Zoom Out/In
Clicking on these buttons zooms in or out of the
Spectral Graph. This lets you view and edit the
noise contour with greater precision. If you have
selected a breakpoint or breakpoints, press
Alt+Start+Plus (Windows) or Control+Op-
tion+Plus (Mac) to zoom the beginning of the
selection to the center of the screen. Press
Alt+Start+Minus (Windows) or Control+Op-
tion+Minus (Mac) to zoom back out.
No Selection: When there is no selection, the Up
and Down arrows move the entire Contour Line
up or down by 1 dB, respectively, and the Left
and Right arrows scroll the display left and
right.
With a Selection: Clicking these buttons moves a
selected breakpoint or breakpoints up, down,
right, or left. If there is currently a selection in
the Spectral Graph, clicking the left and right ar-
row buttons will move the selected breakpoints
left or right. The Up and Down arrows will move
the selected breakpoints up or down, respec-
