Stretch time and shift pitch

With time-stretching, you can perfectly fit voice-overs or other audio to the length of a video scene or web animation. Independently, you can apply pitch-shifting adjustments that range from subtle enhancements to extremely high or low effects.


  1. In the Editor panel, select the desired audio.
  2. Choose Processes > Change Pitch And Timing.
  3. Drag the Time Stretch or Pitch Shift sliders to adjust processed audio relative to existing audio. (For example, to shrink audio to half its current duration, specify a Timestretch value of 50%.)
    The Current and New Duration values show length before and after time-stretching. If you need a specific length, change the New value.
  4. To more accurately adjust a solo performance, select Solo Instrument Or Voice.
  5. To adjust the timbre of instruments and voices, maintaining realism during pitch shifts, select Preserve Speech Characteristics. If realism isn’t desirable (for example, if you want to exaggerate the sound of pitch shifts), deselect this option.
  6. Click Preview, and adjust settings as needed. To compare processed and original audio, click the power button .
  7. When you achieve the best-sounding results, click OK to process the audio file.
