Core Features AI Stem Separation Separate any song into 6 individual tracks with one tap: Drums Bass Piano Guitar Vocals Other Instruments Control each part independently for focused practice and listening. Detailed Stems The busiest tracks can be split one level deeper: Lead Guitar Acoustic Guitar Strings Synth Brass Saxophone Back Vocal Extracted parts become their own tracks, while the rest is grouped into "Remaining Other" and "Lead Vocal". Toggle them any time, solo them, or export them alongside the base tracks. Detail models download on demand and run entirely on your device, so your audio is never uploaded. Import Audio or Video Import audio and video files from local storage or your photo library. You can also record audio or rehearsal videos for practice tracking and content collection. Mute, Solo, and Track Control Mute instruments, solo individual parts, or adjust the volume balance of each track. Focus on exactly what you want to hear and practice. Auto-Detect Sections One tap splits the whole song into sections, with the boundaries lined up to the bar. Each section becomes a loop you can drill on its own — no markers to set by hand. A/B Loop Practice Create loop regions for difficult sections, save multiple practice segments, and quickly switch between them. Improve repetition and training efficiency. Speed Control Adjust playback speed to slow down songs and hear rhythms, details, and performance nuances more clearly. Ideal for transcription and slow practice. Pitch Shift Change the key of a song without affecting playback speed. Perfect for singers finding a comfortable vocal range and musicians practicing in different keys. Project Saving Automatically save practice projects and history so you can continue where you left off. No need to re-import files or recreate settings. Track Export Export separated tracks for sharing, rehearsal, backing track creation, or further practice.
