Change audio speed on your Mac or PC. No cloud.

From the recording

The real run, file by file.

1 file went in and Hangar wrote 1 file. It is the same run as in the recording, with the real names and sizes. Your originals are never changed.

Choose how it sounds

Faster or slower. Voices still sound like themselves.

Keep pitch changes the pace and leaves the voice where it is. Shift pitch lets pitch rise and fall with the speed, the classic slowed or sped-up effect. Both work across the full range.

• Keep pitch

  Start here

  Same voice, new pace.

  Best for podcasts, lectures and narration.

• Shift pitch

  Pitch moves with the speed.

  Best for slowed or nightcore-style music edits.

• 0.25x to 4x

  From a quarter speed to four times.

  Best for slowing a passage right down, or getting through a long recording fast.

The alternative

Why not use Audacity’s speed effects?

Audacity is free and can change tempo, or speed and pitch together, with a full editor around it. Hangar wins when a whole batch needs the same change.

Audacity: the free, open-source audio editor for Mac, Windows and Linux.
