iZotope Radius™ brings world class time-stretching and pitch-shifting to Apple’s Logic Pro™ and Soundtrack Pro™.
You can easily change the pitch of a single instrument, voice, or entire ensemble while preserving the timing and acoustic space of the original recording. iZotope Radius is designed to match the natural timbres even with extreme pitch shifts.
iZotope Radius allows you to change the tempo without affecting the pitch or tone of the performance. Instrument attacks, percussive hits, and the sound stage remain untouched, even at extreme stretches.
Using an advanced hybrid method, iZotope Radius is able to preserve transients and sustained material at the same time. For example, when stretching a recording with sustained brass and pizzicato strings, iZotope Radius preserves continuity of the brass notes as well as the timing and attack characteristics of the strings.
Radius features two modes of operation: Mix mode and Solo mode. Mix mode is designed to work well with polyphonic material such as mixes with more than one instrument, as well as non-harmonic material such as drum loops. Solo mode works best with a single harmonic instrument such as a stringed instrument or the human voice. For finer control, use harmonic correction to manipulate the timbre.
iZotope Radius integrates directly into Logic’s Time Machine™ in Logic Pro 7.2.1 or later. Simply choose "Radius Mix" or "Radius Solo" from the "Algorithm" pull-down menu. For additional control over processing, use the iZotope Radius control panel installed in the Applications folder.
iZotope Radius is available in the Soundtrack Pro "Process" menu with the "Time Stretch…" option.
