116 ESI-32 Operation Manual
Crossfade Looping
The ESI-32 fades between the beginning and end of the loop so that as
the end fades out, the beginning fades in. This virtually eliminates the
clicks and pops that can occur with other types of looping.
Source Data faded in & out with this data
Loop Start Loop End
Crossfade Looping takes sound data from around the loop start point and fades it into the sound data
around the loop end point so that the data at those loop points is identical. In the example above, a
sine wave is crossfaded with silence to illustrate the process.
Crossfade looping is very effective with complex ensemble sounds which
can be virtually impossible to loop otherwise. In most cases even com-
plex sounds can be looped without any clicks or pops. Bear in mind,
however that crossfade looping actually changes the sample data. You
may want to keep a backup of your raw sample data in case the loop is
not satisfactory. In some cases there will be a noticeable timbral shift
during the crossfade. If this occurs, try increasing the loop length so that
the timbral shift is spread out over more time.
