03 / Practice Player
Pull out the hard part, slow it down, change key, and record it again.
Practice Player turns local audio into practice material. Load files, create A/B loops, adjust speed and pitch, and keep recorded takes in a library.
From 0.20x to 2.00x
Speed changes in 0.05x steps. At 1.0x, filtering is bypassed, while changed speeds use the time-stretch path for practice playback.
-12 to +12 semitones
Pitch changes in 0.5 semitone steps, useful for matching song keys, alternate tunings, or vocal ranges.
Mark, drag, and repeat
Save the current position as A or B and adjust markers on the timeline. Playback and seeking stay inside the loop once it is set.
44.1 kHz mono WAV
After microphone permission, PCM stream recording is converted to WAV. While recording, time and level indicators update live.
Recording library and state restore
Recordings store title, path, duration, creation date, and last-used date. Last source, speed, pitch, position, and A/B loop are restored when the app reopens.
