Tempo Loop: Video Slow Downer

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 decipher the hard passages, change the key to match your instrument or voice, and loop exactly the bar that resists you — all with professional audio quality and without altering the pitch.

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

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

PRACTICE LOOPS
• Press and hold on the waveform and drag to create a loop instantly
• A/B button to mark the 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 one tap
• Name them and move them with your finger

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

BUILT FOR PRACTICE
• Music keeps playing with the screen locked, with lock screen controls
• Your library and markers are remembered between sessions: every song keeps its speed, key and loops
• Built-in reference piano to check notes instantly
• Open files directly from the iOS Share menu

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

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