## What is AudioShift?

Learn a tricky passage. Find a key that suits your voice. Record your next idea.

AudioShift brings music practice and creative tools together on iPhone, iPad and Mac. Start with your own audio files, then move between Library, Practice, Studio and Tools in one workspace.

PRACTICE FOR FREE
• Link one music folder and keep up to 10 favorites.
• Slow down or speed up a song without changing its pitch, or transpose without changing its tempo.
• Set a playback range and repeat the section you want to learn.
• Adjust the sound with an eight-band manual EQ.
• Keep practice notes and up to 15 reference images with each song.
• Tune your instrument, play reference notes on the included Upright Piano and keep time with the metronome.

EXPLORE MORE WITH AUDIOSHIFT PRO
• Organize up to 10 music folders.
• Estimate chords, key and tempo with on-device song analysis.
• Save a sound profile for each song with Instrument Focus, Element Reduction and EQ.
• Write lyrics, place chords above the words and transpose your chord chart.
• Record up to eight audio or MIDI takes per song in Studio. Edit MIDI notes and work with compatible microphones, audio interfaces and MIDI controllers.
• In Studio, play the included piano, import supported instruments or use instruments you create in Sampler.
• Build your own sampler instruments: import or record sounds, map them across an 88-key keyboard and combine layers and keyboard splits. Shape each layer and switch between saved groups in Play mode.
• Arrange video, photos and audio on a layered timeline. Trim, split and export a movie.
• Follow estimated sound levels with the Sound Meter.
• Export processed audio or a Studio mix, with your choice of tempo, transpose, EQ and playback range.

LOCAL BY DESIGN
Your audio is processed on your device, not uploaded to an online analysis service. No AudioShift account is required. Practice and export leave your original source audio unchanged.

Bring audio you own or have permission to use; AudioShift does not include songs or download music from streaming services. Cloud-stored files must be downloaded for offline use. Purchases, restoring access and some optional downloads need internet.

CHOOSE WHAT YOU NEED
Free practice tools are available without a subscription. Pro is an optional monthly or yearly auto-renewing subscription. The purchase screen shows your local price and any eligible trial. Manage or cancel through your Apple Account.

Bought the earlier paid app? Verified previous customers retain Legacy access, including song analysis, sound profiles, audio recording and full-song audio export, without a Pro subscription. New Pro features are optional.

Analysis results are estimates. Instrument Focus and Element Reduction use EQ filtering, not stem separation. The Sound Meter is an estimate, not a certified measurement device. Hardware and format compatibility apply.
