What you can do here

Common ways this tool gets used

  • +3 semitones -> 1.1892x ratio
  • -2 semitones -> about 89.09% of the original speed

How to use this tool well

  • This is especially useful when a pitch shift comes from resampling rather than independent time-stretching.
  • Even fractional semitone shifts can be translated into exact ratios here.
