This function takes the audio you have copied or cut and mixes it with the current selected audio range.
After you have cut or copied the audio you want to mix, select the new audio region and then click the Paste Mix button on the Edit tab, select Edit -> Paste Mix -> Paste Mix… from the menu or use Ctrl+Alt+V to open the Mix Direct dialog. You can specify the volume of the mix i.e., the volume of the clipboard audio. When you are ready, click the Paste Mix button.
Almost always the length of the selected regions will be different. If the mix selection (in the clipboard) is shorter than the current selection then the mixed audio will just end when it ends. If the mix selection is longer than the current selection then the mix just continues past the end until the mix selection ends.
A typical example of Paste Mix is where you want to mix a music bed behind a voice over. To do this, see Mix Background.
If the file you are pasting into is stereo you can select the stereo position of the file to be pasted. For example if you are paste-mixing a sound effect you can place that sound towards the left by sliding the pan fader left.
Audio can also be pasted from the System Clipboard (Windows Key+V). The System Clipboard can be used to copy and paste audio to and from other applications.
This function takes the music you have copied or cut to use as background and mixes it with the current selected voice region.

This reduces the volume of a Music-type clip for the Voice-type clip to be emphasized when mixed. This is useful for inserting voice-overs in DJ sets or as commentaries, and for adding background music to podcasts. Use the Duck Level to set the music level for when there is voice and the Audio Up Level to the set the music level for when there is no voice.
Use Fixed Start Lead In Time to make the Music clip play for the specified time before mixing with the current voice selection.
Use Adjust Lead In for Total Time to have a fixed Music Clip length, and align both ends of the Music clip and current voice selection when mixing.
At the end of the mix with the current voice selection, use Fixed End Lead Out Time to ensure that the music clip will continue to play for the specified time.
Use End when Background Audio Ends to adjust the current voice selection based on the music clip length before mixing.
Use Adjust Lead Out for Total Time to have a fixed music clip length, and align both beginning of the music clip and current voice selection when mixing. Choose a Total Time Adjust option to execute how the music clip will be adjusted. Use Adjust Background Start Time to trim the end of the music clip to fit total time. Use Shorten Background to Fit Time to smartly trim the music clip length in the middle to fit total time. Use Fade out Background at Time to trim the music clip at specified length, and for any remaining music clip after the mix to have Fade out effect.
