SoundLab - Stem Splitter
Audio editor and stem splitter
Free · Designed for iPad. Not verified for macOS.
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.
