5.1.8 Loop Tweaker

This dialog allows you to reﬁne a region of audio to loop seamlessly.

The Loop Tweaker can just be used to "tweak" an existing loop selection so that it loops

perfectly or you can also use it to create a loop from material which does not naturally repeat.

To use the Loop Tweaker you must ﬁrst have a loop deﬁned using a pair of loop markers

The Loop Tweaker consists of the following tabs:

Loop points adjustment

This is a visualization of the beginning and end of the waveform between the loop markers.

You use this dialog to manually reﬁne a loop selection by dragging on the waveform left/right

or using the automatic search buttons to ﬁnd the nearest "good" loop point. The aim is to

align the waveforms so they meet in the middle at a zero-crossing point with the waveforms

matching as closely as possible, being "in phase". When you adjust your loop start and end

points within the dialog the start and end loop markers in the main waveform window will

adjust accordingly. Note that this movement may or may not be visible depending on the

amount you move the markers and the zoom factor you have selected.

It is helpful to have the transport looped during playback so you can hear the difference when

you adjust the loop markers within the dialog. Use the Display options to adjust how the Loop

Tweaker waveform is visualized. You can also use the temporary memory buttons to capture

a number of different loop "candidates" and audition them one by one. Note that if you are

not using a cross fade or post cross fade you do not need to click Apply when just tweaking

loop points. You can also leave this dialog window open and manually adjust the position of

the markers in the main waveform windows if you need to make large adjustments.

Cross fade

This tab allows you to apply a cross fade at the end of a loop by mixing a copy of the beginning

of the loop with it. This can be useful to smooth the transition between the end of a loop and

its beginning - especially when using material that doesn't naturally loop. Use the envelope

drag points or value sliders to adjust the cross fade envelope. Click Apply to process the

cross fade.

Post cross fade

This tab allows you to cross fade the loop back into the audio after the end of the loop. This

is done by mixing a copy of the loop back into the audio. Use the envelope drag points or

value sliders to adjust the cross fade envelope. Click Apply to process the post cross fade.

Using the "Copy" button you can insert multiple copies of the loop into the active Audio File,

creating a smooth audio sequence, since copies will loop without an audible transition.

You can access this dialog by choosing Process > Loop Tweaker....
