With Song Split you can separate any song into 4 stems: vocal, accompaniment, bass and drums. All processing takes place entirely on your device, using an advanced neural network, so no server connection or uploads are needed. Import songs files from the Files app or from your iTunes library (non-DRM tracks only). Play back stems, and adjust level, tempo and pitch in realtime. Stems files are always accessible from within the Files app for easy sharing or import into other audio apps. Supported audio formats include: wav, aif, mp3 and mp4.
