If the automatic search for loop points is not successful, you can 
process the waveform to allow for smoother loops by crossfading areas 
of the waveform close to the loop start and end points.
To use the Loop Tweaker, you must first define a loop using a pair of 
loop markers.
Loop Points Adjustment Tab
Use the Loop Points Adjustments tab in the Loop Tweaker dialog to 
manually refine a loop selection by dragging on the waveform left/right 
or by using the automatic...

Refining Loops
You can refine loops using the Loop Tweaker tool.
PREREQUISITE 
Set up a basic loop.
PROCEDURE
1. In the Audio Files workspace, select the loop that you want to 
refine by clicking between its loop start and loop end marker.
2. Select Process > Loop Tweaker.
3. Refine your loop using the settings in the Loop Tweaker tool.
4. Click Apply.
Moving Loop Points Manually
If your loop still has glitches or bumps at the turning points, you can use 
the Loop Tweaker...

Automatically Detect Good Loop Points
The Loop Tweaker tool can automatically search for good loop points.
PROCEDURE
1.In the Audio Files workspace, select the loop that you want to 
refine by clicking between its loop start and loop end marker.
2. Select Process > Loop Tweaker.
3. On the Loop points adjustment tab, make sure that Link start 
and end points is deactivated.
4. In the Automatic search section, specify the Aimed 
correspondence and the Search accuracy.

PROCEDURE
1. On the Loop points adjustment tab, in the Temporary 
memories section, select M.
2. Select one of the five memory slots.
About Crossfades in Loops
Crossfading is useful to smooth the transition between the end of a loop 
and its beginning, especially when using material that does not naturally 
loop.
Sometimes it is impossible to find a loop that does not cause any 
glitches. This is especially true for stereo material, where you might be 
able to find a...

7. Click Apply.
The sound is processed. Each time that you click Apply, the previous 
loop process is automatically undone. This allows you to try out many 
settings quickly.
NOTE
Do not move the loop points after you have performed a crossfade. The 
waveform has been processed specifically for the current loop settings.
AFTER COMPLETING THIS TASK: 
• You can check the crossfade visually by opening the Loop points 
adjustment tab and activating Display processed audio. When...

The Loop Tweaker dialog consists of the following tabs:
Loop Points Adjustment Tab
The top of this dialog shows the beginning and the end of the waveform 
between the loop markers. The bottom of this dialog offers the following 
options:
Loop End - Green Arrows
Move the loop end points to the left/right.
Loop End - Yellow Arrows
Invokes an automatic search for the nearest good loop point to the 
left/right of the loop end point and moves the end point to that 
position....

Overlap
If this option is activated, the waveforms of both halves are 
continued in the other half. This shows how the waveform looks like 
right before and after the loop.
Display processed audio
If this option is activated, the display shows a preview of the 
waveform after crossfading. If deactivated, you see what the 
waveform looks like without crossfading. This option only makes 
sense after you have set up a crossfade and clicked Apply.
Automatic vertical zooming

Crossfade Tab
Crossfade audio at end of loop with audio before loop
To enable crossfading, activate this checkbox. The crossfade is 
applied when you click Apply.
Length
Determines the section length of the audio file to be used in the 
crossfade. Generally, you want the crossfade to be as short as 
possible, with an acceptable result:
• Using a long crossfade smoothens the loop. However, more of the 
waveform is processed, which changes its character.
• A shorter crossfade...

About Looping Seemingly Unloopable 
Audio
Sounds that constantly decay in level or continuously change in timbre 
are difficult to loop. The Loop Tone Uniformizer allows you to create 
loops from sounds that seem unloopable.
The Loop Tone Uniformizer applies processing to the sound that 
evens out changes in level and timbral characteristics in order for a 
sound to loop properly. For example, this is useful for creating looped 
samples for a softsynth...
