Review momentum
54/100
faster than 57% of Music apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Speed Changer | Transcribe+
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.
