Overview

Time & Pitch uses iZotope’s sophisticated Radius™ algorithm to give you independent control over the length and pitch of your audio. It is useful for retuning audio to fit in a mix better, or adjusting the length of audio to deal with BPM or time code changes.

Pitch Contour Module

The Pitch Contour module can be used for faster pitch shifting with the ability to correct variations in pitch over time.

iZotope Radius

iZotope Radius™ is a world-class time-stretching and pitch-shifting algorithm. 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.

Controls

RX 7 is the newest and most capable version of iZotope’s professional audio repair and restoration plugin, pairing next-gen audio analysis and processing with an intuitive interface. It’s designed from the ground up to be approachable for bedroom producers, with the power that professionals require. I just found out Izotope has a bundle that includes this Pitch Correction and vocal enhancement plugin called Nectar. Has anyone recently tried the latest version and how did it stack up against Autotune Live and Melodyne (equal priced). It seems like a cool, plugin if it can hang with the others.

ALGORITHM: You should use Solo mode only when processing a single instrument with a clearly defined pitch. The human voice is a good candidate for solo mode, as are most stringed instruments, brass instruments, and woodwinds. For most other types of source material, Radius mode will usually offer better results. If speed is important, use the Radius RT mode.
SOLO: In Solo mode, the adaptive window size can significantly affect the quality of Radius’s output.
- If the adaptive window size is too small, you will hear a squeaking noise which sounds like the pitch of the audio is changing very rapidly.
- If the adaptive window size is too large then the sound will become grainy as you will begin to hear portions of it being repeated.
- A good approach is to start with the default window size of 37 ms. If the results are unsatisfactory, increase the window size until the squeaking noise described above does not occur. If you cannot get the distortion to disappear, switch to Radius mode for processing.
- Lower pitched instruments and voices may require a longer adaptive window size than the default, but very long adaptive window sizes can cause audible repeating slices of audio.
Formant Correction: Formants are the resonant frequency components of voice that tend to be perceived as characteristics like age and gender. You can shift formants independently of pitch and time by enabling Shift Formants.
- Typically you will leave the Formant Shift Strength set to 1 (full strength) and the Formant Shift Semitones set to 0.
- If you hear what sounds like an EQ adjustment to your audio, you can try lowering the strength to reduce this artifact.
- To achieve special effects, for example to change the perceived gender of a human voice, try adjusting the semitones to a value other than 0.
STRETCH RATIO: Determines how much the resulting audio will be stretched in time.
- Values between 12.5% and 100% will cause the audio to speed up without affecting pitch, resulting in a shorter audio file.
- Values between 100% and 800% will cause the audio to slow down without affecting pitch, giving you a longer audio file.
BPM CALCULATOR: If you are using Radius to process audio for a tempo change, you can also adjust the stretch ratio with the BPM Calculator.
PITCH SHIFT: Controls the amount of pitch shifting up or down that will be applied to the audio.
ALGORITHM: The Algorithm drop-down menu has three options:
- RADIUS: 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 or rhythmic audio. This is the highest-quality option for most sources.
- SOLO INSTRUMENT: designed for monophonic pitched material such as a stringed instrument or human voice.
- RADIUS RT: Good quality, polyphonic, but faster than Radius.
TRANSIENT SENSITIVITY: Determines the algorithm’s handling of transient material. Higher values will result in better preservation of individual transients after processing.
- When stretching percussive material, you usually want transient sensitivity set to its default value of 1.
- If transients in your audio are being “smeared”, a higher value of 2 will tighten up transience at the expense of incurring heavier processing on non-transient audio.
- Bowed instruments such as the violin and cello are especially affected by the transient sensitivity setting. If you hear a stuttering artifact, lower the transient sensitivity to eliminate it.
NOISE GENERATION (RADIUS MODE ONLY): Helps noisy material (like sibilance or snare drums) sound more natural when processed.
- This control will generate noise instead of stretching the noise that is already present in the signal and creating new tones. Higher values of the noise generation parameter will cause Radius to generate noise more often, but can cause some phase artifacts.
PITCH COHERENCE (RADIUS MODE ONLY): Controls the preservation of the natural timbre of the processed audio.
- The Pitch coherence control in the Radius control panel helps preserve the 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.
- Try turning this up for better results if you’re processing a solo voice or a small group of related instruments.
PHASE COHERENCE (MIX MODE ONLY): Preserves the coherence of phase between the left and right channels of the processed audio.
This should be increased if there’s any change in the perceived stereo image after using Radius. It can be decreased when processing a multichannel signal where different channels contain completely different instruments.
ADAPTIVE WINDOW SIZE (ms) (SOLO MODE ONLY): Adjusts the window size in milliseconds of Radius’ Solo algorithm.
- If the adaptive window size is too small, you will hear a squeaking noise which sounds like the pitch of the audio is changing very rapidly.
- If the adaptive window size is too large then the sound will become grainy as you will begin to hear portions of it being repeated.
- Increase this if you have trouble getting good results pitching or stretching low-pitched instruments or voices.
SHIFT FORMANTS: Processes formant frequencies independently of other pitch and time processing.
- When this option is enabled, formant frequencies can be shifted independently of other pitch shifting performed by Radius.
- When Radius performs pitch-shifting without Formant Correction, it will shift these resonant frequencies along with the rest of the audio.
STRENGTH: Adjusts the amplitude strength of the formant correction filter.
SHIFT: How much formant frequencies are shifted. Typically this control can be set to 0, which leaves the formant frequencies unshifted during processing. Adjust this control to fine-tune the formant correction algorithm or for special effects.
WIDTH: Controls the b
