iZotope's Radius plug-in adds a new dimension to time compression and
expansion to Apple's Logic and Soundtrack Pro. With Radius, you can grab
the pitch of any sound source and shift it without changing its timing
or acoustic space. It can even do extreme pitch shifts while preserving
the natural timbre of the original audio. Radius can also change tempo
without affecting pitch or tone. Even used for extreme stretches, Radius
preserves the characteristics of instrument attacks and percussive
hits. And by integrating directly into Soundtrack's "Process" menu and
Logic's Time Machine, applying Radius is a snap.
Features:
- Time compression and expansion with a
light touch
- A truly flexible TC/E algorithm
- An
upgrade for any video post production and sound design arsenal
Time
compression and expansion with a light touch
One thing that sets
Radius apart from other time compression and expansion tools is the way
that it handles transients. Using an advanced hybrid method, iZotope
Radius preserves transients sustained material at the same time. This
function is vitally important when stretching the time of complete
ensembles. For example, when stretching the timing of a piece containing
percussion and swelling strings together, Radius will extend the string
notes while maintaining the sharp attack of the drums; or when shifting
the pitch of a brass section with staccato articulation, Radius
elongates the sustain while retaining the punctuation of the leading
edge of each note while.
A truly flexible TC/E algorithm
iZotope
designed Radius to handle solo instruments and ensembles differently,
because of their different basic characteristics. The two modes, called
"Mix" and "Solo" mode capitalize on the best of time domain and
frequency domain vocoder methods. Mix mode is intended for use with
ensemble or polyphonic sources like mixes and drum loops, and it focuses
on separating the transient information from the sustained background.
Solo mode, as the name suggests, is ideal for a single harmonic sound
source like a voice or stringed instrument.
An upgrade for any
video post production and sound design arsenal
As mentioned
above, there are some features of Radius that are particularly well
suited for use in video post production and sound design. Its ability to
smoothly compress or expand complex background music to fit into a
specific time framework is invaluable. Sound designers will find it
useful for its distortion-free time stretching and pitch shifting while
creating sound effects. Radius also supports pull-up and pull-down
functionality for converting film and video formals.
