Loops

Looping a sound allows you to repeat a section of the sample indefinitely in order to create a sustain of unlimited length. Instrumental sounds in samplers rely on looping organ sounds, for example.

In WaveLab Cast, loops are defined by the audio selection.

To ensure that you find a good loop point, note the following:

• A long loop usually sounds the most natural. However, if the sound does not have a stable section in the middle (an even sustain part), it might be hard to find a good long loop.

  For example, a piano note which decays continuously is hard to loop because the start point of the loop is louder than the end point. A flute is much simpler, because the sound in the sustain section is very stable.

• A loop should start shortly after the attack, that is, when the sound has stabilized to a sustaining note.

• If you set up a long loop, it should end as late as possible but before the sound starts decaying to silence.

• Short loops are difficult to position within the sound. Try to position them near the end.
