Lyloop: Sync & Practice Lyrics

Lyloop is a practice player for learning songs line by line with the music and lyrics already on your device. Load an MP3 and synced lyrics, then loop and repeat each line until you can sing it. Practice any song you like: Pop, K-pop, J-pop, Rap and more.

■ Loop only the hard parts

• Swipe a line right to mark it learned, left to add it to the loop

• Lines that are far apart still loop in order

• Start each loop 0–2 seconds early

• Tap a line to hear it once, then return to your loop

■ Slow it down, sing in your key

• 0.1–1.0× speed. Drag the speed button left or right

• Change the key of each song by −6 to +6 semitones without changing the tempo

• One-tap presets: lower for men, original key, higher for women

■ Follow the sound and the meaning

• The current line scrolls to the center and fills in from left to right

• Romanization and pronunciation in your own script

• Word meanings and sentence notes from on-device Korean and English dictionaries (downloadable language packs)

• Type your own translations or import them as JSON to show under each line

• Switch between scrolling lyrics and a large karaoke view

■ Sync lyrics yourself

• Import LRC, TXT and JSON lyrics, or read lyrics embedded in the music file

• Sync editor: set each line's start and end on the waveform and drag to fine-tune

• Shift the whole song's timing in 0.5-second steps

• Save the finished synced lyrics into the MP3 file (SYLT and USLT)

■ Watch your practice add up

• Per-line progress, mastery rate and resume where you left off

• Practice streak, today's practice time, line repeats and lines learned

• A calendar showing the songs you practiced each day

• Optional daily evening reminder

■ Your data stays on your device

• Music and lyrics play on your device and are never uploaded
