AudacityTry it →Watch full video →Joe at Claricast ·

Demo summary

The narrator demonstrates using the Alt/Option key to drag the edge of a clip for time stretching and using keyboard shortcuts to shift pitch independently.

Step-by-step

  1. Hover your cursor over the top right edge of an audio clip
  2. Hold the Alt key (Windows) or Option key (Mac) until the clock icon appears
  3. Drag the edge of the clip to time stretch the audio
  4. Select the clip and hold Alt/Option while pressing the Up or Down arrow keys to shift the pitch

Options

  • Increase or decrease pitch by semitone increments
  • Slow down or speed up audio for sound design effects

Tips

  • Use these tools independently to avoid the common issue where speeding up audio automatically increases the pitch

Highlights

They've made it really simple to do that.
