Madi: Music & Dance Practice

Slow down music, loop & mirror

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Loop any part of a song or video and slow it down. Sections, A-B loops and 0.25 to 4× speed are free, with no ads. Pro is one purchase, not a subscription. Madi is a practice player that splits songs and videos into sections you can loop. No account, no ads, no tracking. Your files stay on your iPhone. PRACTICE IN SECTIONS Open a song and tap Practice to see the whole track as rows of time (30 seconds per row, or 15 or 60), with your A and B times and the loop length. Tap A start, then B end, and the loop starts. Drag the handles across rows or nudge them 0.1s at a time. Split a track into sections and loop one or several in a row. - Seamless loops with no gap (MP3, M4A, WAV, FLAC, MP4, MOV) - Repeat a set number of times, then stop or keep playing - Sections from subtitle sentences or lyric (LRC) lines - Practice log and next or previous section from earbuds or a page-turn pedal - (Pro) Rest between repeats, count-in, speed ramp (start slow, get faster) and build-up (add one section at a time) - (Pro) Split speech at pauses, or transcribe audio on device to make subtitles and loop sentence by sentence SPLIT VOCALS AND BACKING, FIND CHORDS (Pro) Separate vocals and backing on your iPhone and play the backing only, the vocals only, or a mix, with speed, pitch and loops still working. Save what you hear as a new file. Madi shows the chords and key while you practice and follows pitch changes. Note view draws the melody, and a tuner is built in. BEATS AND 8-COUNTS (Pro) Tap along or detect the beat. Madi shows big counts from 1 to 8, plays a metronome or a voice count in time with the song, and can split a section every 8 beats. METRONOME A standalone metronome lives in Tools: set a tempo from 30 to 240 BPM and a count of 2 to 8 beats, or tap along to measure the tempo. It keeps clicking with the screen off. - (Pro) Spoken counts, a speed trainer that nudges the tempo every few bars, and polyrhythm clicks (like 3:4) DANCE PRACTICE Pinch to zoom on footwork and step frame by frame. With Pro, mirror the video and see yourself next to it with the front camera (on screen only, never saved). LANGUAGES AND SINGING Tap a subtitle line to jump to it, or hold to loop that sentence. Echo (Pro) records you during the rest and plays it back. Show two subtitles, shift timing by 0.1s, and hide subtitles until you tap. Dictation practice marks the words you missed. SOUND Speed from 0.25 to 4× is free and keeps the pitch. With Pro: pitch in semitones and cents, 3-band EQ, vocal reduction, volume boost, and saving sections exactly as they sound. PLAYS WHAT OTHER PLAYERS CAN'T MKV, AVI, WMV, OGG, WMA and DTS audio play through a built-in extended engine. SRT, SMI, VTT and ASS subtitles, embedded tracks, resume, lock screen controls, Picture in Picture, AirPlay, sleep timer, repeat folder and shuffle. Music keeps playing with the screen off. LIBRARY, WI-FI TRANSFER AND NAS Import from Files (whole folders too), Photos and the Music app (songs without copy protection), or send files from a computer browser on the same Wi-Fi. Play straight from SMB shared folders on your home NAS without downloading. Multiple servers and downloads are Pro. PDF SHEET MUSIC Reading, search, bookmarks, night mode and sheet music mode with page-turn pedals are free. Highlight, handwriting, signatures, page editing, merging and scanning are Pro. FREE AND PRO Free: every format, subtitles, sections, A-B loops, repeat counts, 0.25 to 4× speed, background play, one NAS, Wi-Fi transfer, PDF reading. Pro adds the practice, beat, sound, vocal split, chord, camera, NAS, PDF and editing tools above. Pro is a one-time purchase, not a subscription. On another device, tap Restore Purchases in Settings.

  • This app hasn’t received enough ratings or reviews to display an overview.

- Tuner: in Guitar strings, tap a string to choose which one to tune; a string that is far off tells you to “Choose a string”. - Japanese and Chinese subtitle files (Shift-JIS, Big5, GB) now open without garbled text. Two lyric lines at the same time are shown together. - Splitting or merging sections while looping keeps your repeats and speed, and the rest is not cut off. - During a rest, the play button on the Lock Screen responds right away. - Starred sentences follow a file when you rename or move it. - Library Backup (your iCloud Drive) tells you when iCloud storage is low and doesn't retry the same thing. A recorded video that couldn't be added is asked about again next time. - Metronome and sound settings change more smoothly.
