Choose the audio time stretching algorithm
m Choose Edit > Time Stretch > Time Stretching Algorithm, then choose an algorithm from
the submenu.
•
Universal (default): This high-quality algorithm is able to handle any kind of audio material
and is generally recommended for most time-stretching tasks. The following two algorithms
can, however, deliver better results in cases where the audio material exactly matches the
outlined specications.
•
Complex: Choose this algorithm to obtain natural-sounding results when time-stretching
complex musical material—orchestral music or nal mixes.
•
Percussive: Perfectly maintains the timing of rhythmic material, making it a good choice for
drum loops and percussive, nonharmonic signals. In comparison to the Beats Only algorithm,
the Percussive algorithm is better suited for percussive material that has been processed
through a reverb (or contains a long tail). This may also apply to percussive playing styles, such
as staccato electric piano or clavinet parts. Beats Only may be the better alternative for dry
drum recordings.
•
Version 5 (Legacy): Inherited from Logic 5, this algorithm can be used on most types of
audio material. It imparts a particular color on processed audio, which may be a useful
creative option.
•
Any Material (Legacy): Can handle most types of audio material.
•
Monophonic: (Legacy) A specialized algorithm for monophonic material—an individual voice,
or brass or woodwind instrument, for example.
•
Pads (Legacy): Use on polyphonic material with harmonic content—choirs or string sections
are good examples.
•
Rhythmic Material (Legacy): Use on rhythmic material—can be drums and percussion, but less
obviously rhythm guitar, clavinet, and piano comp parts.
•
Beats Only (Legacy): Perfectly maintains the timing of percussive material. This algorithm
should be your rst choice for all kinds of dry drum loops.
