Stem Splitter vs SoundLab

Split any song into clean, isolated stems — 100% on your device, no cloud, no waiting, no subscription. NEW: 6-STEM SEPARATION OffgridStem now separates Vocals, Drums, Bass, Guitar, Piano, and Other — not just the standard 4. Study a guitar riff note-for-note, isolate the piano part, or build a cleaner instrumental than ever. NEW: LIVE REACTIVE VISUALIZER Your exported mixdowns now live in a dedicated Exports player with a real-time, audio-reactive waveform — 14 visual styles including Bars, Neon Glow, Glass, Siri-style Fluid, Circular, Retro EQ, Cassette, and more, plus 4 color themes. Turn your phone sideways for an immersive fullscreen view. NEW: PITCH & TEMPO IN YOUR EXPORTS Shift the key, slow down the tempo to learn a part — your exported mixdown now matches exactly what you heard, not the original. NEW: AUTOMATIC BPM DETECTION Every separated song gets an estimated tempo, shown right where you’re already adjusting playback speed — no need to look it up separately.

SoundLab is a native iOS audio workspace for musicians, producers, creators, and anyone who wants a fast way to inspect, edit, split, and export audio on iPhone or iPad. Import one or more audio files and build a lightweight multitrack session. Each track includes waveform display, volume, pan, mute, solo, and a three-band EQ, so you can quickly shape a mix without leaving the app. Need to understand what is happening inside a track? SoundLab includes real-time spectrum and spectrogram views, plus per-track analysis for duration, channels, sample rate, peak level, RMS, and average spectrum. For editing, SoundLab gives you practical tools that are easy to reach from each track: normalize, fade in and out, reverse, duplicate, and crop to a selected region directly from the waveform. SoundLab also includes multiple ways to split audio: - AI stem separation for vocals, drums, bass, and other instruments - Vocal center extraction from stereo material - Vocal removal / karaoke-style side extraction - Low, mid, and high frequency band splitting AI separation runs locally with Core ML. Your audio stays on device during editing, analysis, mixing, and export. When your session is ready, export the current mix as an AAC .m4a file and share it through the standard iOS share sheet.
