Frequently Asked Questions (FAQs)
Q: What does a semitone mean in music?
A: A semitone (half-step) is the smallest musical interval in western music, equivalent to 1 key distance on a piano keyboard (e.g. from C to C#). 12 semitones equal one full octave.
Q: How many semitones should I shift to fit my vocal range?
A: Typically, shifting by -2 or -3 semitones lowers a song by 1 or 1.5 whole musical steps, making it much easier for lower male voices to sing high pop songs comfortably.
Q: Are my musical recordings secure?
A: Yes! All pitch shifting operations execute 100% locally inside your browser memory. No files are ever sent to remote servers.
Q: Can I change the pitch without changing the playback speed?
A: Yes! By default, Tempo Preservation mode is enabled, ensuring the duration and BPM of your song remain identical while the musical key is shifted.
Q: Is there any cost or limit on how many files I can transpose?
A: No! You can shift the key of unlimited audio recordings completely free with zero watermarks or subscriptions.
