How to change the pitch of the sound file mplayer? I want to make my music sound lower, but not change the speed.

mplayer -af scaletempo=scale=1.0:speed=pitch -speed 0.8 MUSIC.ogg

Set option for speed to pitch and change the separate option -speed to the tone relative to the song. Less than 1 is lower, greater than 1 is higher.

  • This changes the speed unfortunately.

  • Same thing here.... sync is gone. Is there a simpler way to affect pitch straight without modifying sampling rate and video rate?

  • Actually, I got it to sync..... keeping scaletempo and -speed parameter on the same value.... but it makes video/audio go slower/faster. Coming back to original request: how about changing pitch (higher/lower) while keeping the original speed on video and audio?
