1. Choose the Edit tool .

2. Drag the mouse over an area of the data window to select the data you want to mix.

If the Always open dropped files in new window check box on the General page of the Preferences dialog is cleared, you can also drag a file (or region) from the Explorer window to a data window to paste sound data. When the check box is selected, dropping a file on the Sound Forge workspace always creates a new data window.

3. Drag the selection to the location where you want to mix the data. The cursor is displayed as a  , and a shaded selection box is displayed to show you where the mix will occur. An envelope is drawn to show you the mix and fade levels (the last-used settings from the Mix/Replace dialog are used by default).

   You can click the right mouse button while dragging to toggle mix, paste, and CD track drag-and-drop modes.
   

Tips:

• When dragging a selection to mix sound data, drag up or down before moving the mouse left or right. Dragging left or right before moving the mouse vertically adjusts the selection length.

• If you want the Fade In and Fade Out curves to pay attention to the destination selection and file length when mixing between files, select the Auto-crossfade Mix with selection check box on the Editing tab of the Preferences dialog.

4. When you release the mouse button to drop the selection, the Mix/Replace dialog is displayed. If you want to bypass the Mix/Replace dialog, hold Shift when you release the mouse button.

   To customize your mix settings, choose a setting from the Preset drop-down list in the Mix/Replace dialog, or adjust the controls as needed:

   Item	Description
   Source	Drag the Source fader to adjust the volume of the selection you want to mix. Changing this setting has the same effect as dragging the sustain portion of the wet gain envelope in the data window: Select the Invert Data check box to invert the source audio at the baseline (reverse the phase). Inverting data can help match transitions and compare the phase relationship of the two sound files.
   Destination	Drag the Destination fader to adjust the volume of the selection you want to mix over. Changing this setting has the same effect as dragging the sustain portion of the dry gain envelope in the data window: Select the Invert Data check box to invert the destination audio at the baseline (reverse the phase). Inverting data can help match transitions and compare the phase relationship of the two sound files.
   Fade In	Type a value in the Fade In box (or use the spinner) to set the length of the fade in between the source and destination audio. Changing this setting has the same effect as dragging the attack portion of the envelope in the data window: Click the Fade Curves button and choose a curve type from the menu to set the speed of the fade in.
   Proportional Fade Lengths	Select the Proportional fade lengths check box if you want to specify fade lengths as a percentage of the selection.
   Fade Out	Type a value in the Fade Out box (or use the spinner) to set the length of the fade out between the source and destination audio. Changing this setting has the same effect as dragging the attack portion of the envelope in the data window: Click the Fade Curves button and choose a curve type from the menu to set the speed of the fade out.
   More	Click to display additional controls at the bottom of the dialog that you can use to change the selection you want to process.
