- What is a pitch shifter?
- A pitch shifter changes the musical pitch (how high or low a sound is) of audio without changing its speed or duration. This is different from simply speeding up or slowing down audio, which affects both pitch and tempo simultaneously.
- How many semitones should I shift?
- Each semitone is one half-step on a musical scale. Shift by +12 semitones to go up one full octave, or -12 to go down one octave. For key changes in music, typical shifts are ±1 to ±5 semitones. Extreme shifts (±8 or more) can sound unnatural.
- Can I pitch shift video files?
- Yes. Upload MP4, MKV, or MOV files and the audio track will be pitch-shifted while the video remains unchanged. This is useful for adjusting background music pitch in video content.
- Is there any quality loss?
- The pitch shifting algorithm preserves audio quality well for moderate shifts (±6 semitones). Very large shifts may introduce slight artifacts, which is normal for any pitch-shifting tool. For the best results, use lossless input formats like WAV or FLAC.
- What's the difference between this and a speed changer?
- A pitch shifter changes only the pitch while keeping the same duration. A speed changer changes playback speed, which naturally also changes the pitch. If you want both effects together, our nightcore maker speeds up and raises pitch simultaneously.
