Pitch shift moves the notes higher or lower while retaining the original duration. Sonic combines time stretching with resampling so the exported recording keeps its length instead of simply playing faster or slower.
Pitch is measured in semitones from −12 to +12. Zero is unchanged; +12 moves notes up an octave and −12 down an octave. Each semitone multiplies frequency by approximately 1.05946. The default +3 raises a 440 Hz note to about 523 Hz.
Try −2 or +2 semitones before making a large shift. For creative character changes, try an octave, then listen closely to speech and the ends of sustained notes.
Vocal formants are not preserved, so voices can become smaller or deeper as pitch changes. Large shifts may sound grainy, and complex percussion can lose definition. It does not identify the key or choose a musically compatible transposition for you.
This effect keeps the original duration. Use Sped up or Slowed + reverb when you want pitch and speed to change together.
