Tempo Loop Pro

The ultimate practice tool for musicians and music students.

Load any audio or video file and work on the piece like in a professional
studio: slow it down to decode difficult passages, change the key to match
your instrument or your voice, and loop exactly the bar you're struggling
with — all with professional audio quality and no pitch distortion.

SPEED WITHOUT CHANGING PITCH
• From 25% to 200%, with high-quality processing
• Perfect for transcribing solos, working up fast passages or ear training

CHANGE THE KEY
• Transpose in semitones (±12) without affecting speed
• Fine tuning in cents (±50) for old recordings or non-standard tunings

PRACTICE LOOPS
• Press and drag on the waveform to create a loop instantly
• A/B button to mark start and end while the music plays
• Loop edges adjust precisely and snap to your markers

UNLIMITED MARKERS
• Mark the intro, the chorus, the solo... and jump between sections with a tap
• Name them and move them with your finger

WORKS WITH VIDEO TOO
• Load videos and practice watching the performer's hands full screen
• Tap the screen and the controls disappear so nothing gets in the way

MADE FOR PRACTICE
• Music keeps playing while you use other apps
• Your library and markers are remembered between sessions: every song
keeps its speed, key and loops
• Organize your pieces into projects (band, choir, lessons...)
• Built-in reference piano to check notes instantly
• Open your audio and video files directly from other apps

FREE FOREVER, WITH A 7-DAY FULL TRIAL
Download it for free and use ALL features for 7 days. After that, the
player, loops, markers and piano stay free forever; speed and pitch
controls unlock with Tempo Loop Pro (monthly or yearly subscription, or a
one-time lifetime purchase).

Made by musicians, for musicians. If you study an instrument, sing in a
choir, play in a band or are preparing an audition, Tempo Loop Pro is the
tool you'll use every day.
