Algorithms and rendering
AudioSnap
the Radius choices, or for drum tracks, Percussion is usually the best choice.
The following table describes the available algorithms:
To choose default algorithms
1. Press SHIFT+A to open the AudioSnap palette.
2. In the Applies To list, select Default Settings.
Note: You should avoid rendering AudioSnap clips more than once. Applying stretch
algorithms multiple time in succession can degrade the audio quality (similar to transcoding an
MP3 file).
Until your project is mixed and finalized, it is recommended that you use the Freeze function
instead of Bounce to Track(s) or Bounce to Clip(s) if you need to temporarily off-load CPU
processing power. For details, see To freeze an AudioSnap-enabled clip.
Algorithm Description
GrooveClip Good all-around algorithm to use while stretching audio
Percussion Gives a better sound on percussion clips while stretching audio
iZotope Radius Mix Best all-around choice when bouncing to track with audio clips that
contain a mix of different sounds
iZotope Radius Mix Advanced This choice is similar to iZotope Radius Mix, but exposes a
Smoothness parameter (pitch coherence). Pitch coherence preserves
naturalness of timbre for pitched solo voices, such as human speech,
saxophone or vocals. While traditional vocoders can smear these
signals in time and randomize phase, the pitch coherence parameter of
Radius preserves phase coherence for these signals. High values of
pitch coherence will avoid phasiness in Radius's output at the expense
of roughness (modulation) in processed polyphonic recordings.
The Smoothness parameter can be adjusted in the AudioSnap
Options dialog.
iZotope Radius Solo Best choice when bouncing to track with audio clips of a solo
instrument. Although a guitar is a “solo” instrument, if you play chords
instead of single notes you may want to select “Radius Mix” instead.
Tip: if a clip/track contains a mixture of polyphonic and monophonic
parts, you may wish to split the parts into separate clips and experiment
with different algorithms for each clip.
iZotope Radius Solo (Bass) Best choice when bouncing to track with audio clips of a bass
instrument
iZotope Radius Solo (Vocal) Best choice when bouncing to track with audio clips of a solo voice
