What this does

Praat script.

Process Description: This Praat script implements a highly effective technique for performing a pitch shift (transposition) on a selected sound by a specific number of semitones, while ensuring the sound's original duration is perfectly preserved. This is achieved by combining a metadata-based speed shift with a Time-Scale Modification (TSM) via PSOLA resynthesis.

Quick start

  1. In Praat, select a Sound object.
  2. Run script… → Pitch change (semitones).praat.
  3. Set parameters and click OK.
