Disable triple-clicking to select all sound file data

Select this check box if you don’t want to select all data when you triple-click in a data window. You might want to select this option if triple-clicks are falsely detected when you make a selection and then try to perform a drag operation. Otherwise, decrease Windows’ double-click threshold time.

When this check box is cleared, you can triple-click anywhere in a data window to select all data.

Disable auto-snapping below 1:4 zoom ratios

Select this check box if you do not want selections to snap to time or zero-crossings when the data window zoom ratio is less than 1:4.

This is useful if you commonly zoom in fully to adjust selection points manually yet still want to use automatic snapping when zoomed out.

Force loop bar to match selection

Select this check box if you want the loop region to always match the current time selection. Clicking to position the cursor in a data window will clear the loop region. When no loop region exists and looped playback is enabled, the entire data window will play looped. When the check box is selected, the behavior is similar to Sound Forge 8.0.  

Clear the check box if you want to be able to position the cursor without clearing the loop region.

Update loop bar on Mark In/Out

Select this check box if you want the loop bar in a  data window to be updated when you mark the beginning or end of a selection. When the check box is cleared, the loop bar isn’t updated until after you’ve marked both ends of the selection.

This check box is not available when Force loop bar to match selection is selected.

Auto-crossfade Mix with selection

When this check box is selected, the Fade In and Fade Out settings for the Mix tool will pay attention to the destination selection and file length when mixing between files. In the following example, notice how the Fade in and Fade Out curves are adjusted when we drag a selection from one data window to another and move the selection through an existing selection in the destination window:

This setting has no effect in the following situations:

• When the material you are mixing does not overlap either end of the destination selection or the end of the destination file.

• When no selection exists in the destination.

• When you mix data within a single data window.

When the check box is cleared, Fade In and Fade Out setting are not affected by the selection in the Mix destination.

Drag & drop auto rise delay

Drag this slider to specify the time before a window underneath the cursor becomes active during drag-and-drop operations.

Snap to zero-crossing slope

Use this drop-down list to specify how zero-crossings are detected when you choose Snap to Zero:

It is usually best to use either Positive Slope or Negative Slope so that noticeable pops and clicks are not generated by cutting data.

Zero-cross scan time

Specify the maximum time (in samples) that will  be used to search for the next zero-crossing.

Zero-cross level threshold

Specify the sample value below which data will be considered a zero-crossing.

Setting this value above zero can compensate for DC offset. However, if possible, you should remove DC offset first.

Pencil tool maximum zoom ratio

Choose a setting from the drop-down list to specify the maximum zoom ratio at which the Pencil tool will be available.

JKL / shuttle speed

Choose a setting from the drop-down list to set the speed that will be used for scrubbing the timeline with the JKL keys or with a multimedia controller.

Global media cache

Specify the amount of RAM you want Sound Forge Pro to reserve for media recently read from or written to disk.  Reserving excessive amounts of RAM may decrease overall performance.

To turn off the cache, choose 0.

Default FX crossfade

Sets the default wet/dry mix and fade in/out curves that will be used in processing dialogs.
