While in the perspective of reality time can never be stretched, shortened or stopped to a halt, in music (especially in the field of audio processing and engineering) time is a relative concept. Manipulating how sound progresses as well as sounds through time has been one of the activities audio engineers have been very fond of working with, so much so that there have been a host of application (both hardware and software) that are hosting this capability. Adding that time-manipulative edge to Apple Logic Pro and Soundtrack Pro is iZotope Radius, a new time stretching and pitch shifting plugin.

Radius boasts of being a world-class time-stretching and pitch-shifting instrument that can easily change the pitch of any sound, instrument, and even an entire ensemble while retaining the timing and acoustic space of the original recording. This means that Radius can alter pitch while preserving natural timbre even with extreme pitch shifts. In much the same manner, extreme time stretches done via Radius does not alter the tone or pitch of any sound manipulated via Radius. Such capabilities easily lend off to applications such as video post production to fit soundtrack, voice over, and other audio cues to videos, pitch shifting to match vocal and/or instrumental range in recordings, practice, or performances, sound design applications that require distortion-free time stretches and pitch shift, and slowing down recordings artifact free for spoken word and music transcription as well as slow practice.

FEATURES:

• Preserve transient attacks and timing accuracy
• Maintain the acoustic space and sound stage
• Unique hybrid design offers completely transparent operation
• Time stretching between 12.5% and 800%, pitch shifting between -36 and +36 semitones
• Formant correction with adjustable correction strength and correction amount for both Mix and Solo modes
• Preserves Dolby matrix encoding
• Phase coherent design preserves stereo image during processing
• Supports sampling rates up to 192 kHz
