Technical anatomy
Keep Duration Separate From Pitch
A pitch shifter can aim to preserve the source duration while moving tone, whereas changing playback speed naturally affects both duration and pitch.
Check the time requirement
When an audio track must stay aligned to video, compare exported duration with the original after shifting pitch.
Separate pitch from speed
A pitch adjustment changes how high or low a sound is. Retiming changes how quickly the recording plays; choose the operation your task needs.
Review voice character
A shifted voice can have a different timbre even at the desired pitch. Listen to vowels and sustained sounds before choosing the result.
Check your result
Listen for the pitch shift and tone changes
Listen to a known note or familiar voice and compare the result with the source. Check the duration as well as the pitch shift.Check musical interval
Compare a known note before and after the shift. Twelve semitones correspond to an octave in either direction.
Check playback length
Check whether the exported duration meets your needs, particularly when the audio must stay aligned with video.
Check vocal character
Listen to vowels and sustained notes for unnatural changes in timbre after a large upward or downward shift.
Decision guide
Semitones Make the Shift Predictable
Zero semitones keeps the original pitch, +12 moves tones up one octave, and −12 moves them down one octave.
Semitones Make the Shift Predictable
Frequency doubles across an octave upward and halves across an octave downward in ideal equal-tempered pitch relationships.
Choose the result you need
Move the overall pitch of a recording up or down by a musical interval.
Choose a related tool when needed
Use Change Audio Speed to retime a recording. A global pitch shift is different from correcting individual notes, detecting a key, or cloning a voice.
