Search Peak/Silence
Search Peak
Functions > Search Peak scans the currently selected Region for the sample bit with the
greatest amplitude value. The cursor in the waveform display is then placed on this bit.
Search Silence
Functions > Search Silence scans the selected audio for sections containing silence
(“digital zero”). The cursor is then placed at the start of the first section found, that fits
this description.
Adjust tempo…
Just like Automatic Tempo Matching in the Arrange, the Adjust Tempo by Selection &
Locators function adjusts the song tempo, according to the current locator positions
and Sample Edit window selection.
The operation is similar to the Arrange function; it only refers to the selection in the
Sample Edit window, rather than the overall Region length.

Digital Factory
Operation
The Digital Factory functions are accessed via the Sample Edit window’s Factory menu.
• Open the Sample Editor by double-clicking a Region in the Arrange, or the Audio
window.
This selects the whole Region.
• Or: select the area to be edited.
• Or: press Command-A, to edit the whole audio file.
The Digital Factory functions always affect the selected area.
• Select Factory > …
• Make the desired settings in the float window that appears.
Some Digital Factory functions offer a Prelisten button that provides a rough idea of the
expected result. (Not available for all digital audio hardware).
• You can start playback if you wish. Even though the functions alter the data in the
audio file, they can still be performed while the file is playing.
• Click the edit button at the bottom (Process & Paste). The label on the edit button
varies, depending on the function.
