ABLooplay: A-B Audio Looper

Paste a link from a video app and loop any scene from A to B, as often and in as many spots as you like. The sentence you can’t catch, the riff you can’t play yet: slow it to 0.5× at the same pitch. “Loop This Sentence” loops one sentence at a time, no A/B needed. Record yourself and compare. No ads.

■ From here to there, again and again

Watch the waveform and tap A and B — only that part repeats. Pause to pick the gaps by eye, and add a pause between repeats to say it back. Missed a sentence? Tap “Loop This Sentence”: it finds the pauses around it and loops it, no A or B needed.

■ Auto-split by sentence (Pro)

Auto-split › By sentence cuts wherever the sound stops for 1 second or more, making a section for every sentence at once. Set “Plays before moving on” to 3 and long lessons play through on their own. Pro also adds unlimited sections and an equalizer to bring bass, vocals, drums, guitar or piano forward.

■ Compare with your voice

Record yourself with “Record Voice”, then tap “Original → You” to hear both back to back and catch differences in pronunciation and intonation.

■ Half speed, same pitch

From 0.5× to 2× without changing the pitch. “Speed up a little each loop” adds 0.05× per play up to 1×, and the key shifts up to ±6 semitones to match your instrument. Zoom to 3 s and slide the waveform to land on the first word or note, or nudge A and B by ±0.1 s.

■ A–B loops for videos, too

In the Videos tab, paste a video link and it plays in the app; tap “A Start” and “B End” to loop the part in between. Your own videos (MP4, MOV) from the Files app are listed by folder, with a waveform for setting sections. Play counts, pauses, speed and voice comparison work as for songs. Videos from a link have no waveform or Auto-split, and videos stop when you leave the app.

■ Practice log and favorites

Each day you practice 1 minute or more in AB Repeat gets a stamp on the Log tab’s calendar (a star on goal days). Tap a day to see your time and loops, and set a practice reminder there. Tap the star next to “Section 1 of 3” to save a section to a folder, then loop it right away from “Favorite Sections”.

■ An everyday music player, too

Tap a song in the Music tab and a large player slides up; swipe down to browse while it plays. ≡ gives you up next, shuffle, repeat, speed and a sleep timer, and the speech bubble shows lyrics. Search by title, artist or album, and control it from the Lock Screen.

■ Adding audio

Import MP3s from the Files app, singly or by folder, or copy them in from a computer. m4a, wav, aiff, unprotected songs from your music library, podcast episodes and audio from videos in Photos work too. Tracks are sorted by editable ID3 tags (artist → album → song), and empty tags are filled from file and folder names.

■ Also

• LRC scripts and subtitles (SRT, VTT) show each sentence and check your dictation
• A hands-on tutorial with 8 English sentences
• Two columns and keyboard control on iPad; a vertical tab strip on the foldable iPhone Duo
• Speed, sections and key are saved per song
• No ads. Your files and recordings stay on your device; the app only goes online for podcasts and videos from a link

■ Without Pro, and Pro

Without Pro you get the basics: up to 3 sections per song or video, Loop This Sentence, ±0.1 s, speed, key, speed-up, pauses, repeat counts, voice comparison, the practice log, favorites, 2 playlists, and unlimited videos, both your own and from a link.
