How Can We Help?
Welcome to TempoShift support! We're here to help you master real-time tempo and pitch control for your music. Whether you're learning a new song, creating unique remixes, or just enjoying your music in a whole new way, we've got you covered.
Frequently Asked Questions
How do I change the tempo of a song?
Simply play any song and use the tempo slider on the now playing screen. Slide right to speed up (up to +100%), or left to slow down (down to -100%).
Can I change pitch without affecting tempo?
Absolutely! The pitch control is completely independent of tempo. Move the pitch slider up or down to shift the key of any song while maintaining the original speed. Perfect for matching your vocal range or creating interesting variations.
Can I use both tempo and pitch control at the same time?
Yes! Both controls work independently, giving you unlimited creative possibilities. Speed up a song and lower the pitch for a completely different sound, or experiment with any combination you like.
How do I import my own audio files?
Tap the "Imported" tab at the bottom of the screen, then tap the "Import" button. You can select multiple audio files at once from anywhere on your device. TempoShift automatically extracts metadata (title, artist, album) and artwork from your files.
Does TempoShift work with my Apple Music library?
TempoShift works with all DRM-free music in your library. DRM-protected streaming content from Apple Music subscriptions cannot be played due to copyright.
Can I create playlists with library and imported songs together?
Yes! Playlists can contain any combination of songs from your music library and imported audio files. Just tap the + button next to any song to add it to a playlist.
Does TempoShift work from the lock screen?
Yes! TempoShift integrates fully with iOS lock screen controls and Control Center. Play, pause, skip songs, and see your currently playing song all without unlocking your device. Tempo and pitch adjustments are made from within the app.
Why can't I play/find some songs in TempoShift?
TempoShift can only play DRM-free content. Songs with DRM protection (e.g., from Apple Music streaming) cannot be played in the app.
