Short guides for each tool: what you upload, what you change, and what you take away. No engineering deep-dives—just enough to use the app with confidence.
Get a backing track and a vocal stem from a full song.
Upload a mixed song. The tool separates what you hear into two playable results: music without the main vocal, and an isolated vocal line. Use headphones to judge quality; busy mixes may leave a little bleed.
Split one file into several instrument layers you can solo or export.
After upload, you get separate tracks—commonly vocals, drums, bass, and a catch-all “other” band. Mute what you don’t need, balance levels in the player, and save stems when you’re happy.
Open Stem SplitterShift key and tempo to match your instrument or practice goals.
Load audio, then nudge pitch in semitones and speed as a percentage. Preview instantly where supported, then export when it sounds right. Extreme settings may add artifacts—gentle moves usually sound cleaner.
Open PitcherTurn files into the format your device or DAW expects.
Pick input and output formats from the options shown in the tool. The service re-encodes your audio and offers a download when finished. For archiving, lossless targets preserve more detail than compressed ones.
Open ConverterKeep only the part you need—or join clips into one file.
Set start and end points (often with a waveform for context). Export the selection, or combine multiple files end-to-end when the tool allows. Ideal for ringtones, samples, and quick edits.
Open CutterSlow down hard sections and loop them until they feel easy.
Import a track, mark a loop, and reduce playback speed to hear every note. Many musicians use this to learn solos by ear. Export optional if you want an offline practice clip.
Open PracticeSing along with a reduced-vocal or backing-focused mix.
Add your song, follow on-screen lyrics if available, and use a mix that keeps the music upfront. Pair with a good microphone and quiet room for the most fun. Start from a clean source for the least harsh vocal bleed.
Open KaraokeOpen the dedicated notation workspace for scores and sheet-style workflows.
Notation opens in its own view. Use it to work with sheet music or related notation tasks alongside your audio tools. You can return to the main app anytime from the menu.
