BandLab Splitter vs StemRoller

BandLab Splitter separates songs into stems so musicians can work with individual parts, including vocals, bass, drums and other instruments. It runs on Android, iOS and the web, though BandLab notes that features vary by platform and the latest Splitter features may not yet be fully accessible on Android. Free users can upload unlimited tracks, provided each file is under 15 minutes; accepted media includes MP3, WAV, M4A and video. Controls let users adjust stem volume, solo or mute parts, change the split configuration, and modify BPM, pitch or loop sections. Stems can be downloaded as audio or MIDI, or opened in BandLab Studio in either format. The free version separates four stem groups. Pro and Max add guitar, strings and piano isolation and faster separation. Splitter keeps up to three earlier sessions in Recently Imported. The Free plan costs nothing. BandLab Pro monthly costs $14.99 a month after a free 3-day trial; listed annual prices are $99,149 a year for Pro and $199,299 a year for Max.

StemRoller is a free desktop application for turning songs into karaoke, vocal, and instrumental material. Search by song title and it finds results online through YouTube search integration. Using the Demucs machine-learning project, StemRoller separates a song into four outputs: vocals, drums, bass, and everything else. It also mixes the non-vocal stems into an instrumental track. Splitting takes several minutes, and batch processing is not available. The maker describes StemRoller as open source, with the README offering either the Unlicense or MIT No Attribution license. The homepage links to a macOS ZIP and a Windows CUDA executable, version 3.1.1. Linux is not officially supported, although the README provides manual dependency setup instructions. The Free plan costs nothing and includes four stem outputs plus an instrumental track. Questions and issues can be taken to Discord.
