USING ADOBE AUDITION 104 Effects reference Final Stretch or Pitch Shift (Audition algorithm) Changes the initial Stretch or Pitch Shift setting over time, reaching the final setting at the last selected audio sample. Lock Stretch and Pitch Shift (IZotope algorithm) Stretches audio to reflect pitch changes, or vice versa. Lock Initial Strech and Pitch Shift (Audition algorithm) Stretches audio to reflect pitch changes, or vice versa. Final Stretch or Pitch Shift settings are unaffected. Advanced settings (IZotope Radius algorithm) Click the triangle to access these options: • Solo Instrument Or Voice More quickly processes a solo performance. • Preserve Speech Characteristics Maintains realism in speech. • Formant Shift Determines how formants adjust to pitch shifts. The default value of zero adjusts formants together with pitch shifts, maintaining timbre and realism. Values above zero produce higher timbres (making a male voice sound female, for example). Values below zero do the reverse. • Pitch Coherence Maintains timbre of solo instruments or vocals. Higher values reduce phasing artifacts but introduce more pitch modulation. Advanced settings (Audition algorithm) Click the triangle to access these options: • Splicing Frequency Determines how big each chunk of audio data is when you preserve pitch or tempo while stretching a waveform. The higher the value, the more precise the placement of stretched audio over time. However, artifacts are more noticeable as rates go up; sound can become tinny or have a tunnel-like quality. With higher Precision settings, lower splicing frequencies may add stutter or echo. • Overlapping Determines how much each chunk of audio data overlaps with the previous and next ones. If stretching produces a chorus effect, lower the Overlapping percentage, without going so low that you produce a choppy sound. Overlapping can be as high as 400%, but you should use this value only for very high speed increases (200% or more). • Choose Appropriate Defaults Applies good default values for Splicing Frequency and Overlapping. This option is good for preserving pitch or tempo. • Constant Vowels Preserves the sound of vowels in stretched vocals. This option requires substantial processing; try it on a small selection before applying it to a larger one.
