Sonura vs StemRoller

Sonura is an artist-led AI music studio for making loops, vocals, one-shots, stems, and full tracks in a browser or DAW. Its Sonura Split tool separates an uploaded mixed track into vocals and instrumental, or into six stems: vocals, drums, bass, guitar, piano, and other. It accepts WAV or MP3 uploads and returns stems in either format. Sonura says most tracks finish in under a minute, while longer files and six-stem splits can take a few minutes; processing runs on its machines. The page directs users to check the app for the current file-size limit but does not state the limit. For DAWs, Sonura Flow is a VST3 and AU plugin for Ableton Live, Logic Pro, FL Studio, Studio One, Bitwig, Cubase, Reaper, and GarageBand. It is available for macOS 12 Monterey or later and 64-bit Windows 10 or 11, and needs an internet connection while creating sounds. Sonura says stem splitting is cleared for commercial use if users own or have permission to use the recording. The free plan includes daily creation allowances; paid plans start at $20/mo.

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.
