5.If you move the mouse pointer over the graph, a cross-hair cursor follows the 
graph curve and the display in the upper right corner shows the frequency/note 
and level at the current position.
To compare the level between two frequencies, move the pointer to one of the 
frequencies, right-click once and move the pointer to the second frequency. The 
delta value (the difference in level between the current position and the right-click 
position) is displayed...

About time stretch and pitch shift algorithms
In Cubase, time stretching and pitch shifting algorithms are used for numerous 
operations (e.
 g. the Time Stretch and Pitch Shift offline processes, in the Sample 
Editor, or by the Flatten function). Depending on the feature, some or all of the 
following algorithm presets are available.
élastique
The élastique algorithm is suited for both polyphonic and monophonic material....

MPEX
MPEX is an alternative high-quality algorithm. You can choose between the following 
quality settings
: 
ÖWhen applying the Pitch Shift process, you can choose between the regular setting 
and a setting where the formants are preserved for each quality setting. 
Standard
The Standard algorithm is optimized for CPU efficient realtime processing. The 
following presets are available:

If you select the “Standard – Custom” option, a dialog opens where you can manually 
adjust the three parameters that govern the sound quality of the time stretching:
Limitations
Applying time stretching or pitch shifting to audio material can lead to a degradation in 
audio quality and to audible artifacts. The result depends on many factors, such as the 
source material, the particular stretch and pitch operations applied,...

The Sample Editor
Window overview
The Sample Editor allows you to view and manipulate audio by cutting and pasting, 
removing, or drawing audio data, and by processing audio (see the chapter 
“Audio 
processing and functions” on page 302). This editing is “non-destructive”: The actual 
file will remain untouched so that you can undo modifications or revert to the original 
settings at any time.
The Sample Editor also contains most of the realtime time stretching functions in 
Cubase. These can be...

Opening the Sample Editor
To open the Sample Editor, double-click an audio event in the Project window or the 
Audio Part Editor, or double-click an audio clip in the Pool. You can have more than 
one Sample Editor window open at the same time.
ÖDouble-clicking an audio part in the Project window opens the Audio Part Editor, even 
if the part contains a single audio event only. The Audio Part Editor is described in a 
separate chapter, see 
“The Audio Part Editor” on...

Snap
The Snap function helps you to find exact positions when editing in the Sample Editor 
by restricting horizontal movement and positioning to certain grid positions. You turn 
Snap on or off by clicking the Snap button in the Sample Editor toolbar.
ÖThe Sample Editor Snap function is independent of the Snap setting in the Project 
window toolbar or other editors. It has no effect outside the Sample Editor.

The info line
The info line is displayed below the toolbar. It shows information about the audio clip, 
such as the audio format and the selection range.
Initially, length and position values are displayed in the format specified in the Project 
Setup dialog. For information about configuring the info line, see 
“Using the Setup 
options” on page 700.

The AudioWarp tab
The AudioWarp tab lets you perform timing settings for your audio. This includes 
applying swing and manually changing the rhythm of the audio by dragging beats to 
time positions in the grid (see 
“Applying swing” on page 344 and “Free Warp” on 
page 345).
•If you click the “Disable Warp Changes” button, any warp modifications you have 
made are disabled, allowing you to compare the modified sound with the original 
sound of your audio. 
However,...

The Hitpoints tab
On this tab, hitpoints can be marked and edited (see “Working with hitpoints and 
slices” on page 347). Hitpoints allow you to slice your audio and to create groove 
quantize maps from your audio. You can also create markers, regions, events, and 
warp markers based on hitpoints.
The Range tab
On this tab you will find functions for working with ranges and selections (see “Making 
selections” on page 335).
