Cut and Paste Editing

The Cut, Copy and Paste commands, available from the Edit menu, can be used to remove some parts of a soundfile and/or to copy material between different soundfiles. We recommend that for your convenience you 'desynchronize' soundfile windows each time you do cut and paste editing (check None in the Synchronization dialog available from the Window menu or press the SYNCHRONIZE button situated on the toolbar).

Paste buffer

The paste buffer is a temporary file created to store the data transferred from one place to another. Some functions (like Cut and Copy) write to the paste buffer while the others (like various Paste items) read from it.

The paste buffer is erased each time you exit DART XP Pro. If you want to save the contents of the paste buffer, choose the Save paste buffer command from the Edit menu. If you wish to listen to its contents (provided that the material is sufficiently long), use the Play paste buffer command available from the Play menu.

Cut

You can use this item to delete the material from the selected area of an active soundfile and place it in the paste buffer. The Cut function is not available unless a block of samples is selected. Combining Cut with Paste you can move a fragment of a soundfile from one place to another.

Be aware that if signal values at both block edges don’t match local cutting may introduce discontinuities usually heard as clicks. To avoid discontinuity problems use the Smart cut tool available from the Toolbox menu.

Copy

This item copies (without deleting) the material from the selected area of an active soundfile to the paste buffer. The Copy function is not available unless a block of samples is selected. Combining Copy with Paste, you can copy a fragment of a soundfile to another place.

Paste insert

You can use this item to insert (without overwriting) the contents of the paste buffer into an active soundfile starting from the cursor position. If the paste buffer is empty, this function is not available.

Paste over

When you choose this item, the contents of the paste buffer overwrites the contents of an active soundfile starting from the cursor position; the length of the replaced fragment is the same as the length of the paste buffer. If the paste buffer is empty, this function is not available.

Paste fill

You should select a block of samples in an active soundfile prior to using this command. After choosing Paste fill, the contents of this block will be replaced with the contents of the paste buffer. If the length of the selected block is smaller than the length of the paste buffer, only a part of the material is used and the data is truncated to fit. If the length of the selected block is larger than the length of the paste buffer, then the material is copied repeatedly, as many times as needed to fill up the gap.

NOTICE

The system will not allow you to transfer sound material between soundfiles, which differ in format, i.e. have different number of channels, sampling rate or sampling resolution.
