The MPEX3 algorithm allows you to select one of seven
different quality settings:
Ö Note that you can only select the MPEX 3 algorithm if
the time-stretching factor is between 0.5 and 2 through-
out the whole event. For audio that has been stretched
with a factor outside this range, only the Realtime algo-
rithm can be used.
If the audio has been transposed, the dialog also con-
tains the option “Formant Correction”. Activate this if you
want to e.g. avoid a “chipmunk voice” effect.
3. Select an algorithm and click OK.
When the processing is finished, any loop that was previously stretched
in realtime or had been pitch-shifted will play back exactly the same, but
Straighten Up mode will be deactivated and the realtime pitch-shifting
will be set to 0.
The audio clip is now like any standard audio clip before
applying realtime processing, i.e. it will not follow tempo
changes. The flattening processing function is best used
when you have determined the tempo or key of a project,
but you can of course always adapt the audio to a new key
or tempo. In this case, it is better to revert back to the orig-
inal audio clip rather than to process the already pro-
cessed file again.
Option Description
Preview This mode should only be used for preview.
Mix Fast This mode is a very fast mode for preview. This works best
with composite music signals (mono or stereo material).
Solo Fast Use this mode for single instruments (monophonic mate-
rial) and voice.
Solo Musical Same as above but higher quality.
Poly Fast Use this for processing monophonic and polyphonic ma-
terial. This is the fastest setting that gives still very good
results. You can use this for drum loops, mixes, chords.
Poly Musical Use this for processing monophonic and polyphonic ma-
terial. This is the recommended MPEX default quality set-
ting. You can use this for drum loops, mixes, chords.
Poly Complex This high quality setting is quite processor intense and
should be used only when processing difficult material or
for stretch factors above 1,3.
