Sonura vs StemSplit

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.

StemSplit separates songs into vocals, instrumentals, and other stems for karaoke, music production, and audio editing. It offers four-stem separation and a six-stem mode that additionally separates guitar and piano. Users can upload MP3, WAV, FLAC, M4A, OGG, WEBM, AAC, OPUS, AIFF, AIF, or WMA files up to 100 MB, or submit YouTube and SoundCloud URLs. Batch processing is supported, with MP3, WAV, and FLAC exports. The service says most tracks finish in under a minute and advertises separation accuracy above 95%. It runs on the web, through a Chrome extension, and via a REST API with webhooks. Credit packages include API access and do not expire: Starter costs $2, paid once for 10 minutes, Standard $5, paid once for 30 minutes, Pro $12, paid once for 100 minutes, and Studio $30, paid once for 300 minutes.
