StemRoller vs Suno

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.

Suno creates complete songs from text prompts in under a minute. It supports vocal generation, audio uploads, multitrack editing, MIDI sequencing and stem export, with audio export in MP3 and WAV. Tracks can be up to eight minutes long. Users can share music with audiences ranging from a small circle to millions. The Free plan costs nothing and provides 50 credits per day, allowing up to 10 songs daily without a credit card; it does not include commercial rights or monthly song downloads. Free uploads can be up to eight minutes. Pro costs $8 a month and provides 2,500 credits and 20 song downloads per month. Premier costs $24 a month and includes 10,000 credits and 60 downloads. Paid subscribers can use songs commercially, including in videos, albums and other projects. Annual billing gives a 20% discount on both paid plans. Pro and Premier let users create custom models from recordings; Premier adds Suno Studio with MIDI, effects and automation. Suno is available on the web and on Android and iOS.
