Natural time and pitch control plug-in
MFR# Radius

Product Description

The iZotope Radius brings world class time-stretching and pitch-shifting to Apple's Logic Pro™ and Soundtrack Pro™. 

Transpose and Tune 
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. 

Tempo and Timing 
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. 

iZotope Radius is designed for completely transparent operation on a wide variety of source material with nearly automatic operation. It is well suited for both industrial studio applications and home studio use. Applications include: Video post production: fit soundtrack, voice over, and other audio cues to video clips Shift pitch up or down to match a vocal or instrumental range for practice, performance, or recording Sound design: extreme distortion-free time-stretch and pitch-shifting effects Pull-up and pull-down for film and video conversion Slow down recordings for spoken dictation, musical transcription, or for practicing at slower tempos 

Tailor Your Results 
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. 

Logic Pro Integration 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. 

Soundtrack Pro Integration 
iZotope Radius is available in the Soundtrack Pro "Process" menu with the "Time Stretch…" option.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
