Change the Speed and Pitch of an MP3 While Downloading It

When extracting audio from a video you can adjust the speed (0.5x to 2x) and the pitch (±12 semitones) of the MP3, each on its own — no separate app, no extra conversion step afterward.

Speed and pitch, each on its own

If you simply speed up playback, the pitch rises with it — that's physics, not a player quirk. Here the two sliders are independent: speed up a song without it sounding like a chipmunk, lower the pitch without touching the tempo, or move both at once if that's what you want.

What this is actually used for

Karaoke: raise or lower a song's key to fit your range, without changing the tempo you're used to singing it at.

Practicing an instrument or a solo: slow down a tricky passage without dropping its pitch, so you can hear every note before playing it at full speed.

DJ mixing: match the tempo of a track to the next one, keeping the pitch if you're mixing harmonically.

Ringtones and short clips: combine it with trimming and fade in/out to pull out exactly the part you want, already adjusted.

Combines with trim and fades

Speed, pitch, trimming a section, and fade in/out all come out in the same MP3, in a single download. No need to chain tools together: pick the section, decide if you want it to fade in and out, and adjust speed or pitch if you need to — all before you hit download.
