Transcribe+ combines high quality tempo and pitch-shifting with on-device AI that splits a song into vocals, drums, bass, guitar, piano, and other instruments, so you can isolate and hear EXACTLY what you are transcribing by ear. Now on iPhone, iPad, and Mac! Adjust speed and pitch effortlessly with simple swipe gestures. Tap the waveform to pause the track, then drag to listen at your chosen pace, even one note at a time! Attach chord charts that follow the form of the song, mark song structures or add personal notes using customizable flags on the waveform, and practice specific sections repeatedly by defining looped areas. Key Features: • Speed adjustable from 0.25x to 2x without affecting pitch. • Split tracks into 2, 4, or 6 stems (vocals, drums, bass, guitar, piano, other). • Easy pitch modification by +/-12 semitones. • Fine-tune pitch adjustment slider with 1 cent increments. • Interactive waveform interface for real-time scrubbing and listening note by note. • Chord charts from MusicXML, ABC, iReal Pro, or pasted text. • Beats, bars, tempo, and key detected automatically. • Consolidate and practice loops in a single location with Loop View. • Smart Loops can automatically increase speed or shift pitch with each loop. • Load videos for enhanced visual understanding. • Intuitive 10-band EQ toolbar for refined frequency adjustment and additional isolation possibilities. • Mark and annotate waveforms for efficient review. • Easily export loops or entire tracks in eight formats. • Multiple windows and split-screen multitasking for efficient iPad use. • 11 attractive themes with elegant icons. • Keyboard shortcuts compatible with foot pedals for easier control during practice. • Integration with popular cloud storage services. AI Vocal Removal & Stems Separation: Remove or isolate vocals, drums, bass, guitar, piano, or other instruments on ANY track (without DRM). Use this feature to focus on the instruments you're interested in, or create a play-along track. Stems are split entirely on your device, with no uploading and no limits. If an instrument isn't in the song, its stem is hidden instead of filled with leftover noise. Export any combinations of stems and remix them as you like! Chord Charts: Import common chord chart formats you find online. The chord changes run under the waveform, following the actual form of the song. Transcribe+ listens to the whole song on your device and suggests the exact beat where the form starts. If a bar is stretched or squeezed, or the song is heard at double or half tempo, it offers a one-tap fix. Loop View with "Smart Loops": View all your loops in the loop view. Simply tap the loop icon to start or stop a loop. You can set parameters for a metronome count-in before each loop or auto-increase speed or shift pitch with each repetition. Link loops as you learn, starting with small chunks and joining them together with a tap. EQ ToolBar, Channel Mixer, and Fine Tuning Slider: Further isolate or enhance the part you're listening to with the EQ toolbar or the Stereo Channel mixer. You can also finely adjust the overall pitch of the track in increments of 1 cent. Transcribe+ for Mac: Transcribe+ now runs on the Mac, with a full menu bar, keyboard shortcuts, and all of the same features. Apple Music Support: Transcribe+ integrates with Apple Music, letting you adjust the tempo and add flags and loops to any song in your Apple Music library. Please note, due to DRM music streaming limitations, some features are unavailable on Apple Music tracks. iCloud Sync: All of your flags, loops, chord charts, and settings for each track you load are automatically saved to iCloud. These settings also sync automatically across all your devices. Six stems require a device with 8 GB of memory or more; other devices split 4 stems. Beat detection and chord charts require iOS 27 or macOS 27. Terms of Use: https://dynamicappdesign.com/tos.html
